## Transcript

hey welcome back everyone we are here today with another episode of developer office hours we're talking about SCA ready billing let's see you know with SCA ramping up or the deadlines just having passed we're excited to help you out with your integrations and get you ready for for SCA with your recurring billing solutions again I'm CJ Avilla a developer support engineer joined by Zander eben from our user operations team here at stripe he is one of the most informed and knowledgeable employees here and has worked tirelessly to build a great support and learning experience for users that are headed into their SCA migrations as a reminder we have tons of knowledgeable stripes standing by to answer your questions live in chat so go ahead and ask away let's see yeah so the quick agenda we're going to do a quick SCA overview then we'll walk through some code and show you how to how to set up a CA ready billing solution and then we'll have some Q&A at the end yeah so with that I'm gonna hand it over to Zander to tell you a little bit more about SCA great thanks so much TJ hi guys I'm Xander I work on the user operations team at stripe I have been working on preparing our users for for the SEO rules that came into effect on September 14th over the past year so just to give you a little a reminder and overview about SCA a CA is regulation governing online payments within Europe CJ can we go to the next slide so what we're talking about here is payments between customers and merchants in Europe so that means the merchant has to be located within the EEA the European Economic Area and the customers payment method has to have been issued within that area those are called two leg transactions if only one of those were located within the EEA then those would be one leg transactions but so far those are out of scope for strong customer authentication rules so the the deadline for enforcement was September 14th so far we've seen relatively low enforcement across the board that has to do with various different national regulators enforcing at different time lines and we may see increased enforcement over the next year as those into those individual national regulators became enforcement basically what this is mandating is this is mandating two-factor authentication for online payments so the primary method of this is going to be 3d secure both versions 1 and version 2 and so that's something a lot of customers in Europe are familiar with and will be shown in the authentication flow and in the payment flow for payments within Europe can we go to the next slide so something that's really relevant here today as we talk about billing is that there are a number of exemptions to ca payments so as I mentioned a minute ago one like payments are out of scope that's different from exemptions out of scope payments means that no one's gonna going to look at whether they should be requiring strong authentication or not exemptions are different exemptions we have to claim each time we submit a payment and that's what our new payments integrations do the billing payment intents check out those new integrations so it's important to note that a bank can either accept or reject the exemption that we claim when we when we request the payment here's a list of a number of exemptions there also another couple of types of payments that are out of scope but functionally in in this world if they are between European customers and European merchants they work the same way where we were Weston exemption so now I'm gonna hand it back over to CJ to tell us more about our specific topic today awesome thanks here let's see yeah so we're gonna go through again a demo of building some some subscriptions because SCA works a little differently if you're using a trial or if you're not using a trial will show up both we're gonna use the the slim web framework with PHP today to show you know an SCA ready billing solution the stripe API version this video is 20 1999 and you can go find your stripe API version if you head over to the dashboard under slash developers and again if you're watching this later you'll find the code for this episode and other episodes of office hours in our github organization called stripe samples again this episode is centering on SCA ready billing and subscriptions so why don't we just jump right in and look at some code so again I'm gonna start from scratch today so we don't even have a directory set up and we'll walk through the entire process the idea being that we want to show you something really start to finish for building out a subscription so I'm going to make a couple of directories here and then build out some files okay just to show you what it looks like very basic directory structure these are all empty files for right now we're gonna use composer to install some dependencies so we're installing stripe PHP the slim web framework version 3.2 and PHP 10 which is a library to manage environment variables we're gonna use that for our keys we're using slim 3.2 it just has a little bit less boilerplate and because we're gonna be writing is from scratch that's something that we're looking for so now that we that up and running quickly I'm going to make one more change to composure I'm sorry we did this in the wrong directory we want to put this in HP right ok so I installed composer in the wrong directory but we're gonna get it in the right spot now okay we're back we're back back on track here so I'm going to add a script to start the server and very basic it's just gonna start up at localhost for two for two like most of our demos and now I'm gonna edit the index H or the PHP file and just to give you a quick overview of the way that this will work we'll have two pages we're gonna have a a pricing page and an index page the index page will allow us to create a new customer so we're gonna collect payment method we're also gonna collect like the email address of the customer and we're gonna then create the customer we're gonna have a second page called the pricing page and this is you know the typical SAS or subscription pricing page where you see a bunch of different plans and so on the pricing put on the pricing page will just have two simple plant two simple plans and the on the pricing page you'll be able to select a plan and we'll subscribe you to that plan so this is going to be like show plans and select and subscribe to a plan okay so a couple of things that we're going to need here on the server side dot end to manage our environment variables so this is going to load our stripe secret key again only on the server and then we're gonna fire up slim map which will allow us to create basically like the routes that we need on the back end so when we retrieve the route route we're just going to return the index page and we'll come back into the server in a moment to build this out even further for now we can just start up come closer start and that will composure start all right composure all right instead of using composure we'll just save PHP - yes I'm not sure why that's not working if you have an idea of what's wrong I'd love to love to see that in the chat okay so now that that is started we can go into our client and build out this index.html file I think I see what's going on here yeah okay so we had composer installed at the root and inside of the server dot PHP file or directory which caused some confusion here okay so in the index that PHP we're going to start a little demo where we have some a common form where we're going to enter the email address and the card details for a customer okay this is going to be the email the values gonna be Jenny Rosen at sample calm okay and then we're gonna give this a class yield just to make it look nice well the second field here this is going to be the card details so we're gonna use stripe elements card element it's going to be the the ID of our div and this will also have a class field just for for looks and finally we need a button here which is gonna be like the customer create button okay so the the steps that we need now are we want to initialize stripe we want to listen or click on customer button and when the customer button is clicked we will create a new payment method given the card details that were entered into the card element and with that payment method successfully created will then send a request to our server to create the customer so here it can initialize stripe we're going to use install that stripe j/s library initialize stripe here with our publishable key and then grab reference to a couple of these input fields and let's see just for my button and when we click on the customer button this is what we want to do we want to first create a method then create the customer I'm gonna make a function down here create payment method this is simply going to return stripe duck create payment method which is a stripe DJ s function that you can call to create one of the new payment methods so the payment method is a the new representation of a payment instrument you may have seen cards or sources before so payment method is the new SC a ready payment instrument and this takes first argument it's going to be the string card because we're telling it that we're going to create a payment method that is a credit card the second element is going to be the card element which we haven't created yet so we'll go and create we'll go and mount that with stripe elements and the next thing we want to pass is just an options argument with additional parameters so here we can do things like setup billing details on the card that we're creating so we'll do that can pass in the email address the email input value ok before we get too far I do you want to mount that element like card element and that should do it ok so here what we're doing is we are initializing a new instance of elements we are creating a card element and then we're mounting it to the div that has ID card element up here so this will this will initialize stripe elements and allow us to have an input where we can enter credit card details ok and then down below we're creating the payment method and just returning that right now I think also one additional thing that's good to do is handle any errors here so we can say if wants that error you can just alert you'll throw up an alert for the the error message otherwise we want to return risk dot payment method so when you when you call create payment method it returns a promise that's resolved with an object that will either have an error property if it failed or this payment method property which will have the new payment method that you've just created so we're gonna say create payment method here and then because that's returning a promise we can save then create customer this will go we'll go create the the create customer function now okay and this is going to receive the return value from this promise so this is going to get a payment method passed as an argument in the create customer function the way that this will work is we want to send the information that we have collected from our form to our server so we're going to send a post request to our server with the payment method and with the email address and we will get back a customer so here we're gonna say send a post request to our server and we need a new route that we're gonna use to send this information so we'll just call it create customer and we're gonna send it the payment method and we really just need the ID of the payment method that's going to look something like p.m. and then some a random string and we also want to send it to email address okay all right so we are now creating the customer and at the end of that will this log the response for now and I think we're at a point where we can go test this out so again we have just to just a quickly review we have a simple HTML form here that has two inputs we have an email input that is just a classic HTML input for an email and then we have a card element input that is going to be mounted with striped elements and finally you know when we click on the customer button it's going to say create customer that will first create the payment method using stripe GS and the create payment method function and on success of creating the payment method we're going to create the customer so we're going to pass in the payment method and the email address to our server to create the customer so the last step here before we try this out is to go and add a new route to our server called create customer let's go back over here to our PHP file and this is going to be a post route okay we're going to create a customer using stripe PHP so here we're going to say customer is equal to stripe okay and we're gonna pass in the arguments that we need to create a customer so if you head over to the API ref and look at what arguments are available to pass in when you're creating a customer you'll find that there are a bunch of different options that you can pass in this case for the demo we're gonna pass just email and the payment method information so we have the email and then the next thing is the payment method okay all right so now if you were living in a pre SCA world and you have implemented strike before and you're a little bit familiar with how customers and default sources work I wanted to take a moment and just point out that passing in the payment method here does not create a default source so in previous implementations you might have been able to set a default source on the customer and then just pass the customer around and because the customer had a default source it would Auto magically pick which payment method to use when when creating a charge for that customer in the new api's all of the methods that you use to charge the customer are going to expect that you pass in an explicit payment method so when you're creating a payment intent as we've seen in a couple of episodes previous to this one you needed to pass in which payment method you wanted to use to charge to create the payment method to charge the customer similarly when you create a customer like this we are setting the payment method and this will do one of one of the many things that are required to use a payment method with a customer and that is attach the payment method to the customer now this does not again this doesn't set it as a default it just attaches the payment method to the customer so what I wanted to show you next is another argument that you can pass and this is very specific to billing it only works with billing it doesn't work with other with other api yet but this is this is something that you can do if you know that the customer has a default payment method that they want to use for all of their subscriptions you can pass in this invoice settings invoice settings which is an array here of default payment method okay so you have the option when you are building a billing flow to either set this invoice settings default payment method on the customer which will use this payment method as the payment method when creating invoices as part of billing or alternatively you can instead of setting invoice settings default payment method you can set the payment method when you create the subscription so there's two options you can either set invoice settings default payment method or you can set the default payment method on the subscription when you're creating a subscription later so I'm going to work with a customer here that's gonna have the invoice settings default payment method set so that we have only to work with the customer ID okay so let's go test this out pull up will host for two for two and it's a little bigger for you okay all right I want to set a couple of breakpoints here so we can just walk through this so we have a break here and here alright so we have an email address that we have entered the input for the card element has these placeholders telling us that the the element has been mounted properly and so we're going to enter a card the four two four two card has no authentication requirements will click create customer and walk through the code over here as we go so the first thing we're gonna do is create a payment method alright with the the again the second argument here being the card element that was mounted to this input so we're creating a payment method with that four two four two card okay and the promise was resolved with this response object in this case it has a payment method property not an error property so this will skip over this if statement here but I want to also just kind of like show you what this looks like so we get back the the payment method and sometimes folks often will show like okay here's the last four of your card so when you're when you're creating the payment method there the similar the things that you may have been used to seeing as part of tokenization with create token in the old the old set up you would you would see here with create payment method and then again we have the ID of the payment method and this is really the the key this is the the token that represents the card that we just entered and this is going to be the token that we're going to use to attach to the customer and create the customer in the next step so we are returning the payment method and we're done with the create payment method step now we're going to make a request to create customers is going to our server we create the customer object and we give back the customer that we just created on the server side now for the demo I'm just returning the JSON for the entire customer you may choose to return less or you know not expose as much to the client that's really up to you the one thing that we are interested in here is the customer ID that was just created and just as part of the demo what I wanted to show you was that we can take this customer ID and we can use the stripe CLI to fetch stripe Ament methods list list so we can use the stripe CLI to filter out the payment methods so we're saying get the payment methods for this customer that are of the type card and this filters down to show you which payment methods are attached to the customer if for some reason the payment method did not attach then attempting to get the list of payment methods for a customer would just return nothing and then second I want to show you stripe get customers with the with this customer ID so customers because I want to show you that the invoice settings default payment method is yeah so you'll notice the default source again is null that's because we're not using the default source anymore now we're using payment methods so we have attached a payment method and we have also set it as the invoice settings default payment method here so this is the payment method that will be used when we create subscriptions for this customer if we don't explicitly send in a payment method okay so this is almost the last step that we need to do to get our index page working there's one final thing that I wanted to do and that is at the end once we have created a customer I want to redirect to the pricing page with the customer in the URL params so that we can then just pretend that the customer is logged in given their customer ID and use their use their customer ID to create a new subscription so here what I'm going to do is this redirect client side to pricing and we're gonna pass in a new customer and their ID so now when we complete that flow we will be redirected to the pricing page with the customers ID in the URL comers all right so if we test that and create the customer all right and then we have redirected to slash pricing with the customer in the URL params we haven't built the pricing page yet but that's what we're gonna do now all right so onto the on to the next step here so on the client we have this pricing the HTML file we will grab that in just a second and populate it but before we do we need a route on the back end to give us that just to serve up that HTML page so we're going to say pricing okay but now we have a route that will return the pricing page and then we'll start from scratch again with HTML here okay we have an HTML page this one is going to be C okay yeah so we're gonna have a little billing view that has a list of plans and we'll start with starter $9 a month growth $39 a month these plans are something that you set up in your you can either use the API to create new plans or you can set them up in your stripe dashboard and I'll show you that in a moment okay so we are we're going to list the plans and then we'll have these big buttons to subscribe to either the starter Edition or the growth Edition and what we want to do is now we want to create subscriptions for the customer that's logged in so before we get too far grabbed the customer ID out of the params so and that was in the in the query string crams and then let's let's grab reference to these buttons and okay then we're gonna add click events for both of these murder when you click on the starter button we will subscribe to starter when we click on growth we will subscribe to growth alright what does this subscribe to function do let's see that's taking them to plan and then we want to have this create a new subscription for the customer that was passed in as part of the query string parameter subscript and then we'll handle authentication for the subscription and the SCA part of this in a second so create subscription again another route that we haven't we haven't really set up yet on the backend but this is going to take in the plan the name of the plan and the customer okay and then when we get the result we will need to handle any next steps if I get too far what I want to do is add a little debug window as we have in some previous demos plug message and then a little function that will just print out some debug messages so when we subscribe we're gonna say subscribing to em and when we get a response will say subscription created subscription print the ID dated with status I'll just give us the status of a subscription which will be useful when we're we're talking about and looking at how we handle authentication for SCA okay so now that we have this subscribed to create the subscription we're passing in the plan and the customer before we get too far let me show you on the stripe dashboard where you can go and create these plans so if you go into products I'm sorry just mode here yep products you can look at creating a new product which allows you to set up one-time products but we're building a recurring product here demo one this is going to be your unit label maybe you are charging by the seed or by the customer or whatever so we can we can just leave those blank when we create a plan the thing that's really important about the plan and the thing that I wanted to point out is that the ID that you set here is going to be the plan ID which lines up with the ID that we're going to use to create the subscription and all of this is something that you can do from the API to you can you can create your and manage your plans directly from the API demo two one three something like that so here we would say something like demo two monthly one it's it's nice if you have your the IDs formatted in a way that are a little bit readable and represent what the plan is so that when you're looking at your your hard coded plans maybe you can you can read those if you have tons of different plans you might want to just use the auto-generated plan plan ID that comes directly from stripe you said how much the plan cost per month and if there's any trial the trial will not automatically apply to the subscription you'll need to say use the trial from the plan when you're creating the subscription so something to point out but this is really kind of what the what the demo plans look like so I'll show you those quickly so we have two plans growth and starter and those are their IDs starter and growth just just that simple yeah so that that really covers everything I wanted to show you in the dashboard so let's get back into the terminal here and walk through creating the new subscription on the server so this is going to be a new post route create subscription and we're going to say so chené equals red subscription to the eight I think I'm going to move this call to another tab so that we can't we have a little bit more real estate here so KP billing server PHP so we're saying PHP - s beautiful hosts against that PHP okay and then I can you close that all right so now we have a little bit more screen real estate all right so when we create the subscription we are receiving from the front-end the plan and the customer so what we can do here is say customer customer and then as part of creating a subscription we want to pass in two line items each each item in the list of items represents one or many plans that are being subscribed to and relate it to the subscription so it looks a little something like this so this is going to be a nested sort of like a nested associative array where each item in the list has a plan and so we're passing in the plan that we received from the front-end again that's just starter or growth and then again worth mentioning that here if we were not setting invoice settings that default payment method as part of the customer then we would want to set a default payment method here that is one that is already attached to the customer that we're subscribing okay so that's just a part of creating the subscriptions like this okay alright so this will get us started with a basic pricing page I believe so we refresh okay great so now we see a pricing page pretty standard stuff we have a subscribe buttons for the two different plans if we click on subscribe we'll see our little debug message subscribing the starter that goes to our server we get a subscription back that was created with status active great okay we can walk through this similarly but I want to add a few more things before we get too far down the road and let's also test with a card that requires some authentication this is a SCA test card that will require authentication so I just want to show you if we create the customer and set this as their invoice settings default payment method and then attempt to subscribe we're going to get a little bit different status than active so we click subscribe and we're gonna get back the status incomplete now if you have an older API version you might just get a failed message so there's a couple alternatives one is to upgrade your API version another is to pass allow incomplete let's yeah so you can you can say allow enable this subscription to be incomplete with older API versions we didn't want to bake break backward compatibility so you can either upgrade your API version or or pass that flag that allows a subscription to have the status have been complete and incomplete represents a status of the subscription that means that the subscription needs some sort of action to be taken so we have created this new subscription with status and complete and if we look at the console of the subscription that came back so I'll just go to subscribe again we get this response back and if we dig into the response you'll see that there's a couple of attributes here that are interesting one is that now this subscription has a latest invoice so this is one F whatever and it also has potentially a pending setup intent so the latest invoice and the pending setup intent are going to two pieces of data that are related to the subscription that we want to use as part of authenticating the subscription now by default the latest invoice is simply a reference to the ID of the latest invoice that's the default so we have an incomplete subscription and the latest in voice for that subscription will have a related payment intent that payment intent has a client secret that we could use to walk through the authentication but by default we're just getting back the invoice ID and similarly with pending setup intent we would also just get back the ID of the pending setup intent now the what I want to show you was how you can expand the latest invoice and the payment intent related to it so that you can have access to the client secret in the subscription data that is returned as a response of creating the subscription and that also works for pending setup intent I also wanted to talk about the differences between these two and why you would see one versus the other so in this case we're creating a subscription that does not have a trial that means we're attempting to charge we're attempting to collect that first charge upfront and so when we when we attempt that chart we create an invoice and that status is incomplete we have a payment intent related to attempting to collect that first charge and that payment intent will have a client secret that allows us to walk through the flow now alternatively the pending setup intent is used when there's a trial so if you have a subscription that has a trial and we're not charging upfront then instead of having a payment intent and instead of having this latest invoice that we're gonna work with we will we will have a set-up intent the setup intent allows us to get permission from the cardholder to charge the card later so we can walk through the authentication flow to authenticate those card details and get permission to then go ahead and charge later so the case where you do not have a trial you'll see latest invoice that pending setup intent and with pending setup intent I'm sorry you'll see latest invoice with a with a intent and then with a trial you'll see pending set of intent okay so let's let's do the first step which is expanding those two properties so that we have more data to work with on the client so when we create the subscription we can say expand and we want to we can pass in a list of those properties that we want to expand so here we want to say we are interested in having the data related to the latest in voice a man intent and the pending set up intent because we're gonna also show the the trial version later and we just we can expand both of those at this point so we're expanding the latest invoice payment intent and the pending setup intent okay and then from the client when we receive the subscription if status is incomplete and there's a payment attempt so if the status of the subscription is incomplete and if we have a payment intent then I'm going to call a helper here handle card off passing in the payment intent taking the payment intent which will have a client secret and then we can use stripe J s to walk through that authentication flow if we need to so before we get too far let's initialize stretchy s it will include that javascript file and then we'll also to say initialize that client-side instance of stripe of the stripe get a handling card off looks like this striped out handle card payment we pass in payment intent client secret get back a response so handle card payment follows a similar pattern to these other stripe GS methods where it returns a promise that's resolved with an object that will either have an error property or a property that represents the thing that we are creating or confirming so in this case it has an error will say to bug message it doesn't have an error then you will that means that it's successful we went through the the auth flow successfully so we'll just above collected okay so let's see what that looks like sorry I'm switching switching around screens you might read through this again so we're in the case that we have created a subscription that is incomplete because it requires authentication it will have an expanded latest invoice in payment intent and we're gonna pass that payment intent object to handle card off which is a helper here that we've just defined that will take in the payment intent and use its client secret to walk through the authentication flow when the authentication flow finishes we will either have an error property or we'll have the payment intent property and the payment intent profitable reflect but it's been completed we can just we can also log that out here payment intent all right so let's let's refresh the page here we click subscribe subscribing to starter we get back our subscription now that we have expanded the latest in voice you'll notice that latest invoice is not just an ID now it includes a bunch more data about this latest invoice including the payment intent payment intent also has a bunch of information including the amount that we're trying to collect which is the amount for the starter for this first month of the starter level for our billing plan it also has this client secret this client secret is the the tool that we need for walking through the authentication flow so our response status is incomplete and we do have a payment intent related to the latest invoice so we're gonna go ahead and call handle card off handling the card payment will open the authentication modal and then we'll will get this call back when that authentication is complete so we click play we watch watch the authentication modal open so now we are off you're completing authentication for our first for our first payment and as a result we are saying that we are authenticating for this card to be charged again in the future now while this authentication we expect this authentication to work for those recurring payments there is a possibility that you know five six seven months down the line a an issuer requires authentication again for their customer in which case you will need to bring the customer back on session and sort of re walk through this off flow but that'll that'll be an edge case that we don't expect to happen too often but is something that you'll need to to consider and billed for so clicking on this complete authentication represents the user seeing the issuers SCA page here where they would enter their one-time PIN maybe that was extent to them from text or an email and agreeing that they are you know authenticating that this this is their card details and they are agreeing to pay so complete authentication and we'll see that we have complete collected payment and we see that the the new payment intent is here great so that is that is that's it for billing when you have just a flat monthly plan that has no trial so that's that is the process for building the you know the most straightforward and simple billing solution that is SCA ready is handling that latest payment intent and walking through the authentication flow now I want to just like tweak this a little bit and add one adjustment here for handling the authentication in the case where there is a setup intent so we have if the response status is trial and there is response that pending setup intent then what we want to do is we're gonna handle the card setup so this is actually probably like an else--if because it shouldn't happen yep okay so then we're gonna say handle card setup passing in response dot pending setup intent all right ándale card setup is gonna take in the setup Kingston and use the stripe GS method for authenticating a setup intense so stripe handle bird setup guess I should every name that it's it's a little different handles card setup to setup and that client secret thank you similar to this again it's going to return a promise that resolves with either an error or in this case a setup intent and instead of saying that the payment was collected we're gonna say that authenticated card tales all right so that is what the handle setup is going to do is in the case that a card requires some SCA authentication and there is a trial we're gonna walk them through the same authentication flow but this time we're authenticating that they want to save their card but not have a charge right now we need to make one tweak to our server that says when we create this subscription create it with a trial I'm just going to say set the trial period days to 14 days and then for fun we can update our pricing page to say you know 14-day free trial all right so this now our plans show the 14-day free trial when we click Subscribe we will attempt to create a new subscription with a trial in the subscription that comes back is going to look a little different so we can again click subscribe subscribing to starter the subscription came back with the status of trialing okay and we did not enter our auth flow so let's take a look at why not all right let's absque Ribe we get this status of trialing did I spell that right he let's see evaluate yeah true okay and then is there a painting setup intent it is no why is it no play one moment one moment all right so we're getting a pending setup intent back that is trialing but it doesn't have a pending setup I'm sorry we're getting a subscription back it's trying but doesn't have a pending setup intent so let's go through this flow again make sure that we're using an SCA art that requires a CA create the customer alright 14-day free trial subscribing okay there we go oh so the reason that that was happening was because we had already authenticated those card details and didn't create a new customer so we had already authenticated yeah so that test card a particular only requires that you authenticate once so we had already authenticated now now that we're creating a new a brand new customer with a brand new payment method now we have to go through the authentication flow okay that makes sense so one thing to note about that sort of experience that we just encountered and having that payment or the pending setup intent null and a trialing subscription that represents a subscription that does not require SCA okay if you don't have the pending setup intent then that means that either the card details are already authenticated or you're using a card that does not require a CA so here we will complete authentication and we'll see that the card details have been authenticated successfully and we have the setup intent ID and that is it for setting up a trial with SCA so those are kind of the two different flows you either need to handle the pending setup intent in the case of a trial or you need to handle the latest invoices payment intent in the case of not having a trial all right I again we will yeah will share this code up on github and we are around to answer your questions I want it to drop back into the presentation here and point out a few things so we have some documentation for reusing cards we have some documentation for using the stripe hosted check out available for you which is SCA ready and then we have a migration guide if you already have billing setup and you're migrating to an SCA ready solution then you'll want to check out this guide for how to how to migrate to SCA it looks like chat has been really active I've been kind of looking over here and seeing that folks are asking some really really great questions and so I'm hopeful that the stripes that are in chat have been able to answer most of those questions for you our team is standing by and we do have time now just a few minutes to answer more of your Q&A so yeah I would invite Xander if you wanted to jump back on and answer any questions or if any any folks have any any more questions here in chat we can answer those lives yeah so we'll be hanging around for just a bit longer you looks like we've got a couple of questions streaming in here so one of them was around best practices for Form submit when you're creating a subscription so in the demo today what we showed was in in one case we showed how to submit your form details as part of an ajax request to your server i know in older you know in previous integrations one of our recommendations was to take that stripe token that you get after tokenizing and embedding that into your form that will continue to work you can either you know handle the form submit and embed your payment method ID directly into the form or you can use sort of JavaScript to make asynchronous requests back to the server one one other question that was asked was regarding how you might handle different numbers of subscriptions so it looks like yeah and thanks again to Ron for for answering our fir for asking these these were helpful so one yeah so one thing that you can do when you have multiple subscriptions on the page where you have multiple quantity is when you create the items for the subscription and you pass in the plan you can also pass in a quantity so if you are buying for starter editions and three growth you can have two two objects in the list of items that you're sending as part of the subscription and each of those would have quantity two for starter and quantity three for growth for example yeah so that's that's one way that you might handle numerous different subscriptions the billing the billing offering is quite robust and there's a lot of different stuff you can do with metered billing you know usage based type billing scenarios so I would definitely take a look at take a look at the stripe documentation for setting up subscription Billings yeah and again a couple other couple other things I wanted to just round out with here is number one thank you so much for joining and engaging in chat here we'd love to answer your questions so if you have questions after the factor of you are watching this later and you have questions we'd love to hear from you in the Striped channel on freenode IRC you can also reach out to us at support strike calm but yeah we really your engagement in the live chat and your questions are really great to see and we hope that you found this useful and that you know that we're here for you and that this you know in this season of a transition to the new world of SCA compliance if you enjoyed this episode and you want to see some more live office hours and other videos hit that big red button to subscribe we'll be publishing these we're shooting for a you know a pretty regular cadence and so one of the things that we'd love for you to do is provide some feedback so we have a link to a feedback form in the description of the video and we're curious what topics you want to hear about we have an upcoming episode that we're going to be covering la webhooks and all the best practices around web hooks and things that things that we would love for you to consider when you're building your web hook infrastructure especially now that web hooks are you know really table stakes for a lot of these integrations they're required for setting up checkout and setting up many different pieces of a stripe integration and so we want to we want to walk through and talk about ways that you can be really successful with web hooks again there will be a link to the github repository in in the description of the video and at that github organization the stripe samples organization there are tons of other examples and in each of those examples we often share many different server languages so if you're writing in the language that's not PHP you might find a solution in the language that you are more familiar with and so I would go and check out those stripe samples yeah for more information cool I think we are ready to wrap up thank you again so much for watching and we will see you next time Cheers you
