[Music] uh what's up i'm cj avila developer advocate at stripe and today what i want to do is show you the new cvc recollection feature so basically what happens is when you collect payment details with stripe and charge someone's card if you want to charge them again later right now we don't really have a way for you to have the the customer enter the cvc the little the three digits that are usually on the back of their card in order to just confirm that um that it is their card that they're using the maybe it's like it was a previously stored card and you have you know a stripe payment method associated with some card and so we recently released a feature where you can collect or like recollect that cvc when you're taking a payment to confirm that that the card is valid so i wanted to just like run through that super quick um and show you how that all fits together um also yeah totally happy to chat so if you wanted to jump in the chat and say what's up i would be more than happy to chat and answer some questions about your stripe integration so i'm going to start here as we always do with stripe samples create developer office hours this is just like this the easiest way to get up and running for me um so we have kind of like these base templates so i'm using the stripe cli which is a command line tool that allows you to interact with the stripe api and one of the commands is samples and a stripe sample is a github repository with a full like working end to end sample and by saying create and passing in the name of the stripe sample i'm going to be prompted through like what server i want to use and what clients i want to use etc and so today what i'm going to do is pick i think i'm just going to go with ruby ruby is my favorite uh and there's a drag is jumping in and saying what's up i think that might be a halloween mask that's getting ready we are here in october um so i'm going to jump into developer office hours and the first thing i wanted to do is add like one page we'll call it index.html where we will collect payment details and then on another page we'll actually run the payment and we will recollect the cbc for the saved card so i'm going to do this i'm going to create a card element here and what we're going to do is yeah the page is going to be like super super simple we will just have a button that says like save card and this would be like sort of we're simulating the fact that you might collect some payment details from a customer and save that and then when they come back to your site to make a purchase later you don't want them to have to re-enter all their payment details but you might want to like just double check that that's their card and so you want to recollect their cvc so let's see if we can just fire this up rail rails uh ruby or i guess we got a bundle install our dependencies since we're using ruby with a gem file and then i can say ruby server.rb this will start the server on the back end that is running some ruby code and that ruby code for now is just serving up this basic page so right now this is what our page looks like doesn't have very much there and you can't see this card element yet because i haven't mounted it so first i need to install stripe.js you can do like that and then i'm going to grab a new instance of stripe and what we want to do is use elements to add like a card element to the page so this first part is collecting the card for the very first time so all this is actually the same none of this has changed um so let's grab reference to that button and when it's clicked what we want to do is um tokenize that those payment details and pass them to the server so what i actually need to do if i'm doing this in like an sca friendly way or an sca ready way i should use a setup intent to collect the card details the very first time so on the server what i'm going to do is step one create a setup intent on the server step two confirm setup intent on the client step three i'm going to like attach the resulting payment method to the to a new customer this is like what you would normally do as the as the like save and reuse a card flow so the very first thing we need to do is this step one create a setup intent on the on the server and go over to the server and create a new route to create a setup intent create actually i'm just going to call it setup intents and then in here i'm going to simply create a new stripe setup intent dot create dot to json so i'm just going to create a brand new setup intent and render the entire thing back to the client when we receive a post request to set up underscore intents so in the beginning here i need like a a variable called client secret and this is going to contain the client secret for the setup intent so i'm going to send this post request to the server setup intents and right now we don't actually need to pass anything to configure the setup intent but when this when the request to create the setup intent on page load re resolves then i want to update client secret here to data.client secret and this will store the client secret for the setup intent so that later when we when we click the button we will do step two here which is uh confirm the setup intent so what we want to do when the button is clicked we want to call stripe.confirmcard setup and pass in that client secret and then also pass in the payment method payment underscore method and in this case the payment method type that we're working with is card and we want to pass in the card element that we've created okay so this is this is all that we're going to do for now um when the confirmation of the setup intent completes so in most cases especially for us folks this confirmed card setup is going to be basically a no op like it's going to create the payment method and then resolve the promise and give you this new payment method that was tokenized however if you're if you're working with customers in the eu and you're a merchant in the eu and you are subject to secure customer authentication then it's possible that a modal might be opened here and the customer will walk through the secure customer authentication flow and be presented with enough with an auth flow where they have to like maybe enter a one-time pin or authenticate with their bank or some some other similar situation um so uh if that happens after they've completed the one-time actions that are required for the setup intent then also if that's successful similarly we'll resolve here and there will be an object that like either has errors or it has a setup intent and if it has the setup intent then that setup intense payment method is what we want to store and we have like a rock solid payment intent or rockslide payment method that has been created with a setup intent is sca ready and like all all that good stuff so here i'm just gonna if there's any uh errors i'm just gonna alert them um because yeah alerts are like super uh brute force but whatever we'll just we'll roll with it and then uh if if it was successful though what we want to do is we want to attach the resulting payment method to a new customer and so i guess what we can do here is say like let's say create customer or customers yeah customers so we're going to create a new customer and what we want to pass down is the payment method i'm going to say paymentmethod is data.setupintent.payment method notice that um setup intent here is camelcase and payment method is a snake case that's because the setup intent is like the high level nested javascript object that is related to the stripe elements resolution and then payment method this is like the snake case property that matches all the properties in the in the api and so what i'm going to send back after this is successful is i want to send back the customer id and i think we want to send back the payment method id and the customer id and then we'll just like redirect to another page so here what we want to do is like window.location.href equals and then ah man you know what i can let's see let's just do it like hard-coded it's fine charge.html and we will say that the pm is i'm going to take some shortcuts and not like spell out payment method or customer i'm just going to use pm and cuss so that we yeah so data.payment method and data.customer and that should be good so over here we need to implement on the server we need to implement this customer's endpoint which is going to receive a post request to uh slash customers to customers customers um and what we're going to do in here is we want to create a customer so i'm going to say customer is customer stripe actually you know what we can use instead of instead of using data.payment method here i'm going to rename this to resp and then we can use data dot setup intent uh payment method because it'll be it should be the same and then i can just say data.id and render back just that the the exact same thing we did with setup intent but with the customer so i'm going to say stripe customer dot create payment method is data payment method to json so that will make an api call to stripe to create a customer it'll pass in this payment method which will attach the payment method to the customer and then we can use this payment method again later to charge this customer um okay so i am just going to return the the entire customer and so its id should be the customer id that we want um so this is going to be like cuss equals that payment method equals that and we're going to redirect to charge okay i don't know if it's going to work the first time let's just give it a whirl all right so i'm going to open the console here go to the sources tab go to index and then it looks like this is already failing i think we need to restart the server um refresh the page okay nothing is failing anymore i'm going to add a break point in here and i'm also so this is a test an sca test card three one five five it uh four thousand twenty five zero zero zero three one five five is a card it's one of the striped test cards that um will uh require secure customer authentication so we can see what that looks like so if i click save card we when we go into this confirm card setup method we are going to be presented with a modal so you'll see this modal here now in production the contents of the modal will be your bank's page where you're asked for your username password or your one-time pin or some some number they texted you or something so that you can authenticate the payment in test mode on stripe we're just like giving you a button to say authenticated or not authenticated um and then when we resolve we're resolved with this data and again like setup intent here is camel case but everything else is snake case so we go down to payment method that is the string that represents this payment method that we entered so this this card number like these card details should never actually hit your server right um for pci compliance reasons so if you're offloading all of your pci compliance uh like burden or like using elements to offload bci burn then um these card details are sent directly to stripe tokenized it's called tokenize we convert we basically convert these into a string that you can store that's safe to store so this pm 1h whatever is a string that represents these card details and only works with your api keys so no one else can use these all right so we did not get any errors let's see what happens when we hit the fetch customers endpoint it looks like that worked and we resolved with an object here that has an id that is the customer's id cus underscore i something something something and so we're about to redirect to the charge page which doesn't exist yet uh and oh data okay so this should be resp.resp.id so we're we're pretty close pretty close let's see um resp all right so let's restart the server and then refresh this page go through the flow again this time i'm not going to use the sca test card i'm just going to like use the the good old trusty4242 and we were correctly redirected to charge.html with the expected query string arguments so let's go implement charge.html so this is this is where everything new is starting to happen so uh i got to remember 15 minutes in to add to add a timestamp here that um this is when we're going to actually add the cbc recollection so if i say charge.html um and then cool purge so again we want a button and that is like pay let's say pay five dollars just so that we have like something there and then instead of collecting the card details on this page we already have the card details we know that they're tokenized we probably stored them a week ago or a month ago or you know uh maybe it was like 16 months ago we stored these car details when the customer comes back these car details are a little bit rusty and maybe this customer is a different person and we want to just like verify a couple things so we're going to use the cvc element here so i'm going to say cvc element and we're going to use stripe elements to mount just a single input for only the cbc it's not going to have an input for the card number the expiration or the zip code or any of that it is just going to be the cbc um and yeah let's see i don't know the style is going to look not not right but um i think we're i think we're all right so i'm going to copy these two things so we're going to need stripe.js because we need stripe elements and we load it on every page okay script tag let's grab reference to the button again and what are we going to do when the button is clicked we want to we want to confirm a payment we want to confirm a card payment and pass in this cvc that we're collecting so we also need to set up some elements instead of a card element this is actually a card cvc and here this is going to be cvc element and instead of calling this card we'll call it cbc okay so we are mounting the cvc element we're initializing an instance of stripe we're listening to this there's one other thing we need to do and that is like step one is create payment and then step two is confirm the card payment so we need to create a payment intent um payment intents and right now when we create the payment intent what i want to do is pass in um i'm going to pass in the customer id which we have available in params and that should be helpful i'm not actually explicitly sure if that's needed or not but um because we're using a payment method that's stored on a customer i think we need to specify but we can play around with this actually so when when that resolves so a payment intent and a setup intent both have this thing called a client secret which is this string that allows you to confirm on the client make api requests with the combination of your publishable key and this secret to tokenize so let's see so let client secret here and so when this promise resolves we're going to say client secret equal to data.client secret and then we should be able to confirm that we should be able to confirm that later so let's go back to our server and add an endpoint for creating payment intents so we have one for setup intents making for payment intents oops payment i'm gonna make the routes like match what i would write in rails with like the the resources in rails um just to follow like a little bit tighter convention that would match like either sinatra or rails um okay so when we create a payment intent here what do we need uh um i think i can just do like stripe payment create amount is we said five dollars um and then we technically have a customer but i'm going to see if we can get away with not passing the customer here all right so we see the cvc it looks like our element did not mount um cards oh you know what i probably did capital cbc something cvc cbc that's not the one we want a card cbc card cvc ah find and replace it's bitten me it's hitting me before all right so now we have the cbc input box right where we can enter in where we can enter in our our our cvc that's in the back of our card see let me restart the server now that we have that api endpoint for creating a payment intent so let's see if that's working payment intent return with uh 200 there's our client secret that we're going to use okay and so if i enter the cvc123 here um that doesn't actually do anything because we need to we need to implement step two all right so let's go back over here for step two we want to say um stripe dot confirm card payment we pass in the client secret and this is where this is also where it gets new and interesting and different and so we say payment method and the payment method is the string id for the payment method it turns out this works even without cvc recollect recollection uh right cbc recollection just like helps us with this but we have the payment method in the query string params um i'm just going to call it pm again pm and then payment method options this one this is like the new bit that you might not have seen before i don't think we have any videos about this yet so and the payment method options i think we want to go into card and then also into cvc and then we pass it cbc element i believe that's correct but let's go take a look at the stripe.js docs um confirm card payment uh this is the method that we're calling um confirm card payment let me make that much bigger for you here it feels like that's it's like still trying to grow um okay it's probably like way too big right it's just like okay ah all right so we're passing in okay all right okay probably one 125 is that good oh my all right payment method options what why are you so slow what's going on computer is like if i kill zoom and text expander and code runner and where is my memory okay um all right so confirm card payment under payment method options under card under cvc we passed the cvc element okay so that is correct let's refresh so this is the stuff that we're going to start doing here um and then we'll just say like uh whatever happens happens and we'll console log it okay so we've got our payment method in the query string param we've got our customer in the query string param uh when the page loaded we fetched those and we stored those in some variables i'm like super inconsistent between var and let but um you kind of get the point one two three and then click hey and we got an error what's our error invalid request the payment method parameter uh hmm okay cool the payment method parameter supplied pm blah blah blah belongs to the customer cuss xyz please include the customer in the customer parameter on the payment okay so this was the thing i was like let's try it without it turns out it doesn't work without it so customer is data customer good thing we like passed it along though initially right so we've got it and we should be good to go after we restart the server and restart this because we have the customer we for sure have the customer already one two three click pay and the response looks positive and let's like continue here and look at the console we've got a payment intent and the status is succeeded so this is cbc recollection so if you um if you've already saved a card somewhere and someone is coming back to your site to pay and you'd like to recollect the cbc you can do so like this um yeah hopefully uh hopefully this was useful and you got something out of it again like um this is a feature that has been requested like really really highly requested for years going back to 2013 we saw a request for this so this was recently released as of october 2020 and allows you again to recollect the cbc when making payments with stripe so yeah that's it uh let me know what you're building in the description in the comments and uh yeah we'll catch you later all right see ya
