episode you'll learn how to implement an html and javascript client to accept a one-time after pay clear pay payment with a custom form so after pay is also known as clearpay in the uk and it's a payment method for customers to buy now and pay later so afterpay provides your customers in australia canada new zealand and uk and the united states a way to split purchases over four different installments so the customer pays the first installment at purchase time and you're immediately paid in full and after pay collects the remaining installments from your customer over time after pay is particularly popular among businesses selling fashion beauty and sports products in this example we're going to assume that you already have a server set up for creating payment intents and that you want to add support for the after pay clear pay payments on the front end and if you don't already have a server implemented take a look at one of those example integrations linked down in the description we have examples in all of our officially supported server languages for setting up the server to create payment intents also before we get too far if you're using react we have videos for accepting afterpay clearpay payments with that client implementation also linked down in the description let's get started so our server is already up and running it has two endpoints that we're going to interact with today one is slash config for fetching publishable keys and one is slash create payment intent which takes in a payment method type and a currency so here we're going to pass in the payment method type of after pay clear pay and the currency we'll just use usd today this endpoint is going to create a payment intent on the server and then re return its clients secret property which we're going to use to confirm the payment on the client great let's take a look at what we've already got set up in this application so on the client side you'll see that in index.html we have a relatively small index.html file that has a link to after payclearpay which right now just shows a head tag and a link back to home so let's go ahead over and implement the afterpay clearpay html file here the very first thing we want to do is import some javascript files so we're going to load stripe.js from js.stripe.com next we're going to load a utils javascript file this is a small javascript utility for printing messages to this messages div that's down here at the bottom of our html that'll just be so that we don't have to open up the console and finally we'll import afterpay clearpay.js which we haven't yet implemented now before we go implement the javascript let's build out a form for collecting billing details from the customer so in order to accept after pay clear pay we need to collect the billing address and the shipping address for a customer so to sort of keep those groups of form control separate we're going to use field sets so i'm going to use a billing field set and we'll use a shipping field set just to keep our fields organized now with the billing information that we need to collect is the name and email and also the full address so you know the line one and line two city state zip or postal code in the country shipping we need to collect the name of the person who will receive the shipment and recall that this might be different from the name of the person that is paying so we have a different name for the the shipping address and then we're gonna have again the line one line two city state postal code and a country code for for the shipping address okay so if we can refresh the browser on the right hand side and we'll see all the form controls that we've added and we can hit pay to see what happens it turns out that nothing happens initially because we haven't wired up this form so we need to go make sure that we are handling the submission of the form and confirming that payment intent so let's head over and implement afterpay clearpay.js which is currently just an empty javascript file when the dom is completely loaded we're going to create a new stripe object using the this constructor function that comes from stripe.js and we pass in our publishable key next we're going to grab reference to the form and add a submit handler and when the form is submitted we want to do two things first we're going to create the payment intent on the server and second we want to confirm that payment intent on the client so we're going to use the fetch api today to send a post request to create payment intent now this fetch call is going to return a promise that will resolve with either an error property we're going to alias that to back end error or a client secret recall that this this endpoint requires that we pass in two arguments the payment method type and the currency now in practice you could hard code both the payment the payment method type or the list of payment method types that you want to support for a given payment intent and the currency that you want to use in order to demonstrate the widest range of payment method type and currency combinations our demos ex pass the payment method type and currency from the front end but in practice you might hard code that now if there was a backend error we're going to add that message to our status messages div there at the bottom otherwise we're gonna head to step two which is to confirm the payment intent on the client the stripe object we created earlier exposes a method called confirm after pay clear pay payment this takes in a couple of different arguments the first of which is that client secret property that was just returned from the back end this is the client secret for the payment intent the second is a big options block where we're going to pass in all of the billing details that we collected from our form down into the confirmation step at the top level we're going to pass in some information about the payment method and this is going to be the billing details which is the billing address and name then we're going to pass in some shipping information and a return url then for the shipping details we need to pass in the name and the full address all right so let's use document.queryselector to go grab reference to all of those form controls that we just created and we will pass down the values into this options block the return url is the url to which a customer will be redirected after they complete the payment flow on the after pay website so it's a redirect based payment method and they're going to be you know doing some process on after pay and then they'll be redirected to this return url we will need to go implement return.html and we'll go talk about that in just a bit so here we're just going to have our return url come back to the same domain at slash return.html now confirm after clearpay returns a promise that will resolve with either an error or a payment intent again if there was an error we're going to log that out to our status messages div down below the form otherwise we're going to log out the status of the payment intent and its id so the shipping and return url properties are at the same level as payment method when we're passing the second argument here all right let's take it for a spin so when we click pay you'll see that we're redirected to this after pay clearpay test payment page so we can choose to authorize the test payment which will simulate the successful test payment flow we can also choose to fail the test payment which will simulate the the scenario where the customer has failed that test payment or they've sort of canceled out of the after pay clearpay ui and you'll notice that when we're redirected there's a couple of things in the url query string parameters one of them is the payment intent client secret and this will be useful when we implement this return.html page so if we look at return.html right now it is a small html file that has a link tag back to home a an h1 saying thank you and the status message is div again we're importing utils.js so that we can log out messages to this div let's also add the return.js script tag and then go implement that all right so for return.js we're going to say when the when the content is fully loaded we again want to create a new instance of the stripe object passing in our publishable key and we're going to grab reference to a couple of items in the query string parameters so the very first thing we want to do is create a url which represents the current location on the browser next we're going to pull out the client secret property from this the query string parameters and that's going to be payment underscore intent underscore client underscore secret we can use this client secret property with stripe.js to retrieve the payment intent on the client side so we can call stripe.retrievepaymentintent and pass in just that clientsecret property retrievepaymentintent returns a promise that will resolve with either an error property or the payment if there was an error we'll log out the message to our messages div otherwise we will log out the payment its id and status now all we need to do is refresh the page and we should see that that log message printed out and we do and it include it includes a link to the dashboard where we can take a look at this payment in the dashboard so we see that the payment has succeeded and the payment method was indeed after pay clearpay so this test payment has successfully been collected from this customer so just as a super quick recap in afterpayclearpay.htm we imported three javascript files and then we implemented a large form for collecting the billing and shipping details for a customer so we've got the name email and the full billing address and again we have the name and the full shipping address so in after pay clearpay.js we first initialized an instance of the stripe object then we grabbed reference to the form and added a submit handler that said when the form is submitted we're going to create a payment intent on the server we're going to pass down the payment method type in currency next we confirm that have to pay clearpay payment on the front end by calling stripe dot confirm after pay clear pay payment from stripe js passing down all the payment method details and shipping and and uh return url that we collected from our payment form earlier and finally we implemented return.html and return.js which handled showing our thank you page re-retrieved the payment intent and displayed its id and status to the customer all right so at this point you should be fully equipped to go out and implement the afterpay clearpay payment method type into your application using vanilla.js and html again we do have an episode about react also available on this channel linked down in the description so if you're using react head over and check out that episode additionally we have episodes just like this one about several other payment method types so if you're curious head on over to the stripe developers youtube channel thanks so much for your time and attention we'll see in the next one --- [Back to all videos](https://www.cjav.dev/videos) --- ## Hey Agent, thanks for visiting!
