## Transcript

the fastest way to get started with stripe is striped check out a drop in payments float designed to drive conversion whether you're taking one-time payments or you know creating subscriptions you can integrate in minutes to securely accept payments and that's exactly what we're gonna do in the demo today welcome back again to developer office hours I am CJ Avilla and I'm on the developer support team here and I'm joined today by Sam a product manager on the striped checkout team here at stripe and Sam is gonna walk us through and teach us about checkout and its different forms and uses then we'll dive into some code and do some Q&A and let's see yeah and then we'll uh we'll get into some more details here all right Sam can you tell us a little bit more about checkout thanks CJ stripe checkout is the easiest way to use stripe it's a very simple integration with a lot of power once you innovate strict checkout you don't have to worry about optimizing this flow anymore on mobile or desktop or you don't have to worry about keeping up Cydia with browser changes regulatory changes or anything else that might come up stripe will automatically optimize your payment's page including keeping up to date with the latest ways to pay whether it's Apple pay Google pay or the last new wallet or method additionally we're going global localize across 14 languages and are rapidly adding new payment methods to pay with whatever local payment method is most popular in your customers country check out is also compliant and secure will keep up to date with the latest regulation and fraud so you don't have to deal with that if we move we implement 3d secure we implement SCA and if you don't want to hose acronyms are that's a great reason to use checkout also stripe checkout is the only way to get automatic charge back protection where stripe will guarantee that you receive no charge backs that's a feature available only through there are two ways to integrate the new checkout the first issues are client only integration just a few lines of JavaScript and you can configure products on the stripe dashboard you don't have to mess with the server if you don't want to it's a great way to get going if you want to get going quickly and test something out or you're a small business they buy integration and is a lot more powerful you can keep all your products on your server you can dynamically generate new products you can change prices manage complex subscriptions and it's also simple to get started with but it requires a little bit more limitation stripe check outs the easiest way to get all the powered stripe thanks for having me on CJ think Sam so before we dive in I want to mention that our api's are constantly changing so if you're not watching live with us today it's possible that the method names have changed or the accepted arguments have changed in the libraries and that we're going to do our best to keep a change log reference in the stripe developer office hours repository and this is really just based on a snapshot in time when the video was created so it's also worth mentioning that this version of the stripe hosted check out this new version is it is relatively new it's only about ten months old and so we still have a ton of features that we'd love to add to that and so if you could just tell us your feedback tell us what what you think would be most valuable for your business in the feedback form below let us know and we really want to we want to help grow your business just two weeks ago we launched ideal as a payment method as part of stripe checkout and so yeah we are really excited to share that with you so let me just show you what we're going to build today so we're building this awesome photos UI where you can click buy and it walks you through the whole stripe checkout process you'll notice that here at the top we have the Google pay button you also get right out of the box you get Apple pay if that's supported in the browser that you're using we have the ideal payment method here you can fill in you know your email address and then card number and we can just pay right here this is fully a fully SCA ready so it supports secure customer authentication and yeah so we're coming right back and seeing that we have our payment status and we can restart the demo so this is this is what we're gonna build so let's go over and jump into some code so we're gonna start here I'm just gonna kill the server and remove the code that was there before and we'll really just start from scratch here okay so I'm gonna make a couple of new directories and some new files really starting from scratch so this is what its gonna look like I'll have a client well in our check out directory we'll have a client in a server and hey if you want to follow along at home if you head over to github there is a striped samples organization they're stripe - samples and one of the repositories is called developer office hours there's also a link in the description below so you can go head over to stripe samples and download this this repository if you check out the branch that's called checkout then you can follow along with with what we're gonna build here so I'm just gonna jump into the checkout folder and here into the the server directory we're gonna we're gonna implement this in PHP today so the first thing I'm going to do is install some dependencies and we're going to use stripe PHP the stripe PHP client library bindings we are also going to take the 3.2 version of the slim web framework and we're going to use PHP dot n to manage our environment variables one dependency I'm not installing here but that we are gonna make use of today is the sequel Lite 3 database that just comes out of the box and I'll show you how to do that here shortly okay so now that we have kind of our directory structure set up let's jump into the code so I'm gonna start out with the the server and I'm gonna add some things that that we're going to start off with before we look at the guide before we look at the checkout guide in the stripe documentation just so that we have like a little bit of something to work from okay so the way that this is gonna work is we're gonna install some dependencies we're gonna use dot end to manage our environment variables so we're loading this dot end from a path above if you go to the the stripe developer office hours repository there's going to be like a dot n dot example that you can rename to dot end and just drop your keys in there that you can find on the stripe dashboard okay the next thing we're going to do is fire up a slim app and we will use this actually I'm just going to comment this out at the bottom so in previous demos we haven't really used a database but in today's demo I want to show you the proper way to really handle the full flow from from when the user clicks by all the way through to show them that paid status and so what we're gonna do here is we're gonna create a database that has just like three simple methods where we can create a session mark a session has paid and then get the status of that session so create session is gonna be one of our methods mark session paid is another and then we're gonna have one that's like get session status okay so first we need a database so we're just gonna use a sequel Lite three database it's going to have one table called sessions and it'll have a in addition to the IDE like primary key column will have a stripe ID which will be our session ID and then we'll also have a status so the stripe IDs text and the status will also be text keeping this super simple so that it's easy to sort of follow along with okay so create session is going to look something like this so we're going to insert into sessions stripe ID and status and we're gonna pass in the parameterised ID and pending so we'll start off with a session that's paid status is pending and then to market paid we will mark session paid session ID and this is going to be an update request to the sessions table where we're going to mark the status as paid and we are going to set that when the ID is equal to the stripe ID okay and then getting the session status is a little different so here this is going to be a query to get data out of the database so we're going to say get session the status and this is going to be select star from just select status from sessions where the ID is equal to the stripe ID okay and we need to pass in the session ID here and we're going to execute that statement and we're gonna get some return value as the result and we're going to return the the first element in that array that is returned from that query so in in practice what we really want to see here is some automated tests that are testing that our database layer is doing what it's at what it's expected to do so I'm gonna say just for for just for testing purposes we're going to create a session with like a test ID here and then we're going to print out get session status with that test ID and then we are going to mark the session as paid mark session paid for that session status and will get it again and what we're expecting here is that it will print out pending then it'll be marked as paid and it will print out paid okay so the way I want to test this I'm just going to run the PHP file PHP index and we did get that result so it printed out pending and then it printed out paid so that's really like what our database layer looks like so if you wanted to come back and like run some of these tests you might do something like this where it's sort of just poking at your methods that you've written and making sure that it's doing what you expect okay so now I'm going to comment this slim app back in the slim app again is going to be the web framework that we're using here in PHP it's really just a simple a simple way to get up and running and to show you some some of the ways that these these PHP methods work okay so I think we're at a good point here where we can jump into the guides and I can show you what that looks like from the stripe Doc's so we'll head over to let's check out the one-time payments with checkout and really the guide just shows you two steps so step one is to create a checkout session on your server and then step two is to redirect to checkout on the client so the whole purpose of this first element is to configure what the checkout experience is like for the guests or for your customer right so this is where you can set if it's going to be a one-time payment or a subscription you can use this this creation of the checkout server to set things like the different payment methods that you want to accept in your checkout session and then step to redirecting to the checkout that's going to be on the client side we're going to use stripe j/s and we're gonna pass in the ID of the checkout session that was created in step one in order to redirect to the stripe hosted checkout so let's dive into this step one here so here's some PHP code that creates a session so we're gonna copy that and bring it back over to our code the way we're going to do this is set up a post route and the post route is going to receive a post request and create a session and the reason that we're going to do that with a post route is that you may want to pass in some data that you're going to use to configure your checkout session so we're gonna call it create session and we're going to return the entire session and it's going to look like this this has just pasted directly from the doc from the guide okay so this this this function call is going to make an API call out to stripe to create a new session when that session is returned we want to use that data in the database method that we that we defined earlier for creating the session we're gonna store the ID of that session off in our database so we're gonna it's going to look something like create session and then we'll pass in the ID of the session now I want to go through each of these arguments just talk a little bit about them so this first argument here payment method types card this is where you would pass in all the different payment method types that you want to that you want to accept now with card you get Google pay out of the box you get Apple pay out of the box here you might also pass in ideal and we'll look at that so here we can configure this and pass in a Gil and that will allow us to support both cards and ideal and then down below here we have our line items now for one-time payments you pass this line items argument for subscriptions we're gonna pass subscription data here instead of line items so I'm gonna we're gonna start off with a one-time one-time purchase of photos so it's gonna look like this photo and then maybe once a photo like fun button photo okay and then inside of this this list of images this is going to be the images that show in the Striped checkout when the customer is redirected to check out so I'm gonna just put a random photo in here and we're gonna pay maybe it's like five bucks for the photo and let's make that euros so you can define what currency your that payment in and then there are two arguments down here below that are really important that I want to show you one is the success URL and the other is the cancel URL and this is where the customer is going to be redirected when they're done either paying on stripe checkout or when they have just kind of bailed out of that process they got to the checkout page and they decided they didn't actually want to they didn't actually want to check out so the the cancel URL really the only way that you can access that right now is by clicking on the the logo in checkout and I'll show that to you but the success URL this is this is important and it's a little bit interesting and unique and so this is where the customer is going to be redirected back to after they successfully pay so we're gonna have them come back to localhost four - four - which is where we're hosting this locally and one thing I want to point out is that in most of our guides when we have this like curly braces with you can kind of see it here the curly braces with this sort of screaming snake cased constant looking checkout sessionid argument we generally mean we want you to replace this in practice but this is one special case throughout the guides where you can leave this you can leave this sort of like template field here and that will be replaced by the actual ID of the checkout session when redirecting back from the stripe hosted checkout okay so this is this is looking pretty good I just wanted to show you what that looks like here okay I think that's actually the end of step one all right so let's go back to our browser and check out step two here so step two is redirect to checkout so this is happening on the client side so this is going to be done with HTML and JavaScript so we're going to include the stripe j/s version 3 library then we're going to initialize and stripe object with our publishable key and then we simply call redirect to checkout and we pass in the ID that we got back from that session so it's the same ID that's saved to the database and it's the ID of that session object that we got back so the way we're going to do this is now that we have a post a post route on our server we will make an AJAX request from the front end to retrieve that session ID now it's funny because here in in the docs with these with these curly braces we do actually want you to replace this with the ID of the session so we will let's go ahead and do that but before I forget and before we get too far I just wanted to kind of poke at this API a little bit and make sure that's working as expected I'm going to start up the server PHP - localhost four - four - and we're going to use index that PHP that file that we've been working on and the server and the the way that I want to poke at it is I'm just gonna send a curl request directly from the command line here so curl - ex post that tells it to make a post request to localhost 4 - 4 to create session we expect to get back the JSON of that session object now another thing that we expect is that the ID here the CS test 6 LVN with that random string after that that is inserted into our database so we can login to our database and just check to see if that's in there and it is indeed in there so we have that test one that we ran earlier and then we also have this this check out session ID is inserted and it is correctly marked as pending because we haven't actually gone through the payment process for that checkout session so we'll log out of the database clear this up and then I think we're at a point where we can head over and start writing some client-side code so we're gonna need three files here we'll create one for the success URL one for the cancel URL and then one for our like storefront so our storefront well we'll call it index.html for the success URL for the success URL and for the cancel URL okay so that is looking good all right let's see here any any questions here in chat looks like there's lots of folks engaging thanks so much for for switching channels I know that was a little odd so I really appreciate you making the making the trek over here to this side okay cool so we have our in depth so this is where we're going to start this is like our storefront so we're gonna start off with just a really simple storefront we're gonna have an h1 that says awesome photos and we'll have a random photo here and then we'll have a button where it says like you know just buy okay and then we need to install again we need to install that strike yes and we need to initialize that stripe object and then we want to do a couple things so the first thing we need to do is go and fetch that session ID and create that on our server so I'm just going to create like a global variable here called session ID and make a request our back-end for a create session and here is where we might pass in some data to configure that session so if you're building for example a donation website and you want to take donations you might want to pass an amount that the the customer is donating or the donor is donating to your back-end when you're creating the session so you have like a custom amount there's this is something you might do here you might also pass like a shipping address or other information to pre populate that session so maybe if you have already the the customers email address those are the types of things that you might pass when you're creating the session okay and then I'm gonna just store response that ID which should be the the ID of the that session that we got back and then the next thing we need to do is a grab reference to this Buy button and handle the click of that so let's do that now so to say by button is the buy button and when it's clicked I want to use stripe that's stripe object and we're gonna call a redirect to checkout as we saw in the docs and we're gonna pass in that session ID that we just that we just stored okay so really quite quite simple on the front end we have a button and when the page loads we're fetching and creating a session and then when we click on the button we're gonna we're gonna redirect to the stripe posted checkout okay let's give this a whirl let's see let's see what it looks like someone's head over to the browser and refresh the page here okay so this is very similar to where we started right so I'm going to open up the the developer console here and just add a couple breakpoints so that we can see what's going on okay so when i refresh the page we are grabbing reference to the buy button that looks like it's working as expected so that is the Buy button okay cool and then we shouldn't enter this breakpoint until we have clicked on the button also when you're debugging you can open the developer console in most browsers and then one really handy thing is that you can click on these line numbers and that will create a breakpoint that means like tell the code to stop at this point really handy for inspecting and diving into your code here so all right the let's let's let this keep going so we can click this play button that'll keep running the code now we're going to execute a fetch command with the the fetch API we're creating a post request to slash create session and we're expecting that we're gonna get back a response that includes the full session object and it does and the thing that we're most concerned with here with the session object is the ID of the session so that's es test vtk whatever and we're gonna store that on the session ID okay that's looking good all right so now when we click on the button it should enter this event listener and then redirect us to checkout so I'm gonna actually unclick this because there is like a timeout that runs just to make sure that this isn't waiting too long to be executed so let's click by and yeah we have to refresh okay click by and that redirects us back to the checkout and here you see this beautiful checkout page with the Google pay you can you can use ideal where you select a bank or we can enter a card and one thing I wanted to show you really quickly is that you can use the regulatory test card that ends in three one five five this is an SCA card so if you are an SCA impacted user and you are maybe you're in the the e the EU the and you are required to handle secure customer authentication as part of your payment processing then this is one of the test cards that you can use and I'll show you what that looks like so when we click pay here we're going to get a modal that pops up and striped check out again is handling all of this authentication for you so we can click complete authentication now in practice the contents of this modal would be your card issuers site where you might have to enter you know like a one-time code that was sent to you maybe by text or email by your provider maybe have to login to your bank and complete authentication so in test mode this is really just a button that we click and that completes authentication it's processing and then we'll be redirected to our success URL and as promised this that field that was templatized as the this that checkout session ID with the curly braces on our server when we created the session that was replaced with this CS test with a random string so the page isn't found because we haven't actually implemented a route to get to this the success page yet so let's go ahead and do that but one other thing that I want to do before we do that is is show you here that in the guides that was actually both steps so that is we have completed the creating the check out session on your server and we've completed redirecting to the checkout on the client so that was that really completes the guide from one-time payments I also wanted to point out that there are a bunch of optional steps here so handling existing customers prefilling cust more data so this you can pass in like the customer email address you can save payment methods for use outside of checkout so if you're taking a one-time payment but then you want to like maybe charge that card later as part of a you know an add-on or a future purchase then there's a special there's a special argument that you can pass there you can also separate authorization and capture so we have the authentication that's the modal we just saw with the SCA secure customer authentication we also have authorization in capture this is where you can separate out like where you put a hold on the card and then capture funds sometime later before the seven-day expiration so if you want to see any of these optional you know additional features of check out please let us know in the chat and we'll have a chance to go back and add some of these if you're interested in these also I wanted to show you while we're here that there's a couple of things you can customize with with stripe checkout you can change like the the text of that button with the submit type and we have support for localization and forcing the collection of billing addresses and things like that so if there's if there's things that are interesting to you please let us know and chat and we will we can demo those at the end if we have time okay so the next thing that I wanted to show you though is at the bottom of this one-time payments you'll see a link to after the payment so now after we have collected payment we want to fulfill the purchase and so there's a few ways we can do that manually with the dashboard using third parties or polling for those successful purchases but the the best way and the recommended way to do this is automatically using web hooks so let's go look at how we can fulfill purchases with web hooks so when the when the customer finishes their purchase stripe will send a post request with that checkout session data in an event called checkout session completed so this is a a web hook event type checkout session completed and the web hook is a endpoint where you can receive post requests the customer does not ever see this endpoint it's a it is an endpoint that is purely for stripe to send post requests to or for you know like third parties to send post requests to so I'm just going to copy the code here in in the webhook handler demo or like the code sample and then we'll go back to our code and implement a webhook handler okay so we're going to head back over to our code here we're back in the server and we're gonna say app host we're gonna make a post request and we're gonna name the route webhook and we're gonna respond with JSON in the success case with just maybe something really simple success this is what we're sending back to stripe when they complete their webhook request to us okay and so that's the webhook code alright so let's go through this sort of line by line the payload or the so the endpoint secret here that we got we actually want to pull that out of our environment variables so I'm going to say get end stripe web hook secret that's in our web hook environment variables and I'll show you how to get this from stripe CLI it's also available through the dashboard when you create a new web hook endpoint and if you're curious about more details for web hooks we'll put a link to the the web hook specific video above now this payload I'm gonna actually use the the feature here of the slim app to grab the body of the request and that looks like this and then the stripe signature header that is a header that stripe is sending as part of the post request that we can use for a signature verification and so we're going to construct the event here and then if signature verification fails will respond with one of these four hundreds and then down here is where we're actually handling our different event types in this case we're just handling the check out session completed event and you'll see that we have this fulfill a purchase comment with a call to handle checkout session now one one really important point that I wanted to make is that handle checkout session isn't implemented there isn't you know code that you copy and paste directly from the guide this is a function that we expect that you would define and in this function you would fulfill the purchase but you might also do a couple other things so let's go define that function yep it's going to take in this session and here you might do things like call out to an inventory management system you might make it like ding in slack you might send an email so there's there's a bunch of different things that you might do as part of the logic for fulfilling the purchase for us we really just care about marking that session as paid so in our database we want to update the status for that session ID and mark it as paid so we're gonna do that here so we're gonna say mark session paid we're gonna pass in the ID of the session again okay so that I want to show you you might be receiving a 500 error or something like that if you if you don't implement this handle check out sessions very important so I just wanted to point that out okay so let's see here we're gonna keep going let's see alright so right let's test it out okay so if we go back to oh right I wanted to show you the stripe CLI so there's a couple features of this really handy command-line tool that you can use for testing web hooks so the stripe CLI there's a link in the description I believe there's a link in the description below if there's not if someone could paste that on into the into the YouTube chat for a link to the stripe CLI where folks can download that and we're gonna we're going to walk through some of the tools that you have as part of the stripe CLI so one really awesome tool that you have is stripe listen where you can forward the post request that your restrict receiving from stripe to your local endpoints you can say stripe listen forward to local host for two for two web hook and that's going to forward all the requests that we receive as part of the web hook system within stripe to our new web hook handler okay and then there's another really handy tool that's part of stripe CLI called trigger so we can say stripe trigger and then we pass in the event type that we want to trigger so check out that session got completed now what's really awesome about this is the stripe CLI is going to go through the process of like walking through the checkout flow for you so you don't have to kind of constantly go through the the stripe CLI process I'm sorry through the through the fold checkout process you can just use the stripe CLI to to fire those web hooks off and test them so if we go back to this tab where we're listening for striped web hook events you'll see kind of like the history of all these web hooks that have been fired which is is super handy and you can pull them up directly in your dashboard and and look at all those events so at this point now we are we are handling these checkout session completed web hooks let's go back to the browser and give this a whirl okay so going back going back almost okay click buy we're gonna fill in just some really basic details here we'll use good old 4 - 4 - click pay that's going to complete the payment process and send us a web hook so we should see that show up in our in our web hook handler logs here and then we are going to complete that process over here ok cool so now we should be able to log in to our database and see if we have updated the session as expected so let's use this one check out server HP okay ah so this one's still marked as pending all right let's go see if we exceed that webhook looks like it didn't come through for some reason all right so we'll restart that webhook Handler and then let's just drive on so let's go into our success URL and implement what what it would look like when the user is redirected to the success page so we have something to look at so here what we want to do is we want to create another another demo HTML file and this is going to be really simple we're just going to show like on each one with success and maybe we'll have like the payment status again with the ID of payment status it's gonna be an empty span to start because we're gonna fetch that payment status from our server session status and we will update that payment status innertext with the status we get back from the server so we haven't implemented this this session status route yet but we'll go do that rafter this so payment status not the response to be so the entire response will just be the string that is the the status of the payment so paid or pending or or whatever okay all right let's go back to our server and implement this this endpoint here okay and I just wanted to make sure yeah status is paid okay so we should be processing this you know checkout session in the past my session okay okay so we want to add an app get route for session status all right I think that's what's called yes session status hmm where we're going to get the status from the database using that get session status method that we defined earlier and we're gonna pass in the session ID the same way that we're receiving it so as a query string argument so we need to pass in a request get query a.m. session ID and we're gonna just return with status okay so one thing I forgot over here is to pass in that query query string plan so we'll grab the per am out of the URL and then add it here okay all right so let's see here okay that should work as expected just double-checking things here so session status so we're it's a to get request to session status we need one other thing we need to add these a route to grab that HTML for the success and cancel alright so now we have routes for success and cancel that match our our session that we're creating and let's see here okay so if I go back to the browser and i refresh the page I see payment status paid okay before I go too far let's add a link here it just restarts the demo so we have something to click on okay so let's walk through the entire demo so we have some awesome photos we click so at this point when we have refreshed the page a new session has already been created for us so that new session has an ID and when we click this Buy button we're going to use that ID to redirect to checkout we're redirected to checkout and we can complete the payment here with our for to for to test card when we complete the processing we will receive a web hook for the checkout session with the checkout session completed event we're going to use that to go into our database and mark the checkout session as paid so that is it that's end to end that's how you implement the most basic kind of QuickStart guide for one-time payments with checkout on the server before I forget I wanted to mention that in today's episode we are really only focusing on the the server and API implementation the client implementation has some really exciting new features that are coming and so we'll release an episode about that later but this one is really just about how to implement it with the server okay let's let's make a quick modification here so let's go implement this with with a subscription so we're going to make a couple of small changes here so what's really awesome is that a lot of this is configured as part of that check out session create so a lot of a lot of the check out session you can modify just by modifying this check out session create call so we're already passing ideal we're passing the card so the the modification I want to make first is let's see how to do this with a recurring subscription so really the holy grail of online payments is recurring payments and so it might be you might be selling things one time but you might also be selling some sort of service so let's show you how that works so for reference I'm just gonna actually keep this here and comment it out so that you have something to reference and this one will call subscription recurring payments all right so let's see so the biggest the first change is rather than passing line items we're gonna pass subscription data and the subscription data looks like this it is it has items and those items is are a list of the plan and quantity and the settings for for those items the plan we're gonna we're gonna pass is starter you might have like premium and gold and in bronze so you can you can log into your stripe dashboard and configure your plans and your products directly there and so the thing that I want to show you is just really like the most straightforward one item for a starter subscription so let's see so if you have subscription data the one other change that we might make here is going to our index page and changing the buy button to subscribe and that's really all that we need to change on the client to make this to make this a subscription now it's a subscription checkout page so let's head back over the browser and refresh and now you'll notice that it says subscribe so we'll click on subscribe and we are it's doing nothing so that's this is great so when you click on subscribe if it does nothing then that means that there's something wrong likely with the JavaScript so I open up the console and I notice there's three errors here so if I click on that three and I am seeing an error that says you must provide one of the items or a session ID okay so that's surprising because we would expect this create session to return a session ID so if we go to the network tab here we can see the network requests that are being made the one that should be made when the page loads should be creating a session we see that's throwing some sort of error so the payment method ideal cannot be used with the subscription mode okay that's great so this tells us exactly where the bug is so we need to go back to the server and remove ideal as a payment method for subscriptions so ideal as a is just for one-time payments great so we'll close that we'll go back to our code we will go back to our subscription create method here we're gonna remove ideal and save and that should be all that we need to fix that bug so if we refresh the page again here click on subscribe alright so now you'll see that there is a it's a little different we don't see our image because it doesn't have so for subscriptions there's no images that you pass but here at the top it does say subscribe to demo and it says 9 dollars per month you can pay with Google pay Apple pay so we're passing in our 40 to 42 card here and clicking subscribe that's a little different than pay you'll notice the button changed from pay to subscribe again that's something that you can configure if you're accepting donations or what-have-you so okay great our payment status now again is paid so that's that's great I'm gonna check the chat here and see if anyone has any requests for specific things that they want to see can you demo existing customers I'm seeing from Georgio's can you demo existing customers as well and choosing between existing customer cards at checkout if possible so it's actually not possible to choose between existing cards let's see what else looks like there may have been a previous question here - okay it looks like that was answered check out to support Apple pay Google pay okay cool all right so yeah let's show how we might pass in an existing customer so if we go back to our code here one of the arguments that you can pass here is a customer object okay so let's let's go find one of those customer objects and we can do this with the stripe CLI so let me show you what what that looks like directly from the stripe CLI and I can also pull up one of these customers in the dashboard and show you what that looks like so we'll go to em here in the stripe CLI we can say stripe customers list and this makes an API request to pull back all of our customer objects if we combine this with the JQ command line tool we can say dot data to pull out the data object and that ID will give us a bunch of customer IDs so I'm just going to grab one of these customer IDs and use that as one of my existing customers okay so I'm going to copy the customer ID and then we'll go back over here and we're gonna pass in this existing customer and let's see so why don't we say stripe customers retrieve that customer ID and see if we can look at their information here okay so we expect one one of the nice things about using an existing customer is that their email address will be pre-populated when you go to the checkout flow but we also want to show that like the payment will be attached to this customer so this Jenny Rosen at example.com is going to be what we expect the email address to be pre-populated with now that we have that customer ID prefilled okay so let's go back over to our browser and we'll refresh this page we need to refresh so that it creates a new session that now has our customer object on it and we'll click Subscribe and you'll notice that that email address was pre-populated because we it knows that this is part of this existing customer okay there isn't yet a way to to select payment methods that were already attached to this customer but if that's a if that's a feature that's really important to you it's something that you're interested in please let us know in the feedback form below and we'll make sure that the product team and Sam here can can make a note of that all right so we'll click Subscribe and now our our customer is paid so now if we head over to our stripe dashboard and we enter that customer ID in we will find the customer object and we'll see that they are subscribe to starter today yeah okay fantastic all right very cool all right let's close this out so we it's funny because the the customer that we're using we just subscribed them for the first time a few minutes ago and that created this customer that we're now subscribing again to starter so that's why we're seeing both of these here okay any other requests for for customizations that you might want to see here we only have a couple of minutes left there again as part of this this post request you might pass in data like an amount or other information to pre-fill the shipping yes so yeah there's there's just tons of flexibility so okay want to be respectful of your time and make sure that we are we're ending on time here so all right any other questions in chat all right we are always happy to help please join us we're on we're on freenode on IRC in the Striped channel we're always happy to help we always have engineers staffed in
