using fpx financial process exchange or fpx is a malaysia-based payment method that allows customers to complete transactions online using their bank credentials bank negara malaysia or bnm the central bank of malaysia and 11 other major malaysian financial institutions are members of the paynet group which owns and operates fpx it's one of the most popular online payment methods in malaysia with nearly 90 million transactions in 2018 according to bnm so let's say you already have a back-end set up to create payment intents and you want to add support for accepting fpx payments on the front end if you haven't already implemented a backend head over and take a look at one of those server side implementations in one of the officially supported server languages we have those linked down in the description also before we get too far if you're using another client like react we have videos specific to those clients also linked down in the description so our backend is up and running and it has two endpoints that we're going to interact with today one is slash config for fetching our publishable keys and one is create payment intent and this endpoint is going to accept two arguments we're going to pass the payment method type here we're going to pass fpx and malaysian ringgits this endpoint returns a client secret for that payment intent that we're going to use to confirm the payment on the front end all right so let's take a look at what we've already got set up we have an html page here with a link to fpx.html and this is what we're seeing in the browser on the right hand side now if we take a look at fpx.html notice that there is a basic html page already created for us the first thing we're going to do is add three new javascript tags the first is to install stripe.js from js.stripe.com this is a best practice to load on every single one of your pages we're also going to install utils.js which just has a little helper function to add messages to this messages div here that's at the bottom of the page and finally we'll install fpx.js which is where we're going to implement our javascript today all right let's add some html for the payment form in this case we're going to collect the name and then we're going to use an fpx bank element from stripe elements in order to render a list of bank elements now when we refresh the page you'll notice that fpx bank is just showing the label and there's not actually showing the control because we need to use stripe.js and write a little bit of javascript to mount a stripe.js element into that control let's head over to fpx.js and get started the first thing we're going to do in our javascript once the dom is fully loaded is create a new instance of the stripe object passing in our publishable key next we're going to create that fpx bank element and mount it into the div that we created earlier when we call elements.create and pass in fpx bank we also are able to specify an account holder type now we can call fpxbank.mount and pass in the css selector for the div that we created earlier that's sort of the container for the element that we want to mount now when we refresh the browser we can see that our control has been populated with all of the banks that are available with the fpx bank element all right let's now grab reference to the form control and add a submit handler and when the form is submitted we want to do two things first we're going to create a payment intent on the server and then we're going to confirm that payment intent on the client here we're going to use the fetch api this is the built-in fetch method that allows us to make api requests directly from the browser and we're going to send a post request to create payment intent and it will resolve with either an error or a client secret property recall that this endpoint accepts two arguments we're going to pass in the payment method type again fpx and the currency again malaysian ringgits if there was any error returned from our server we want to log that out into a little messages div here so we're going to use the add message function that again comes from util.js it's a helper that is really just to print out into this into the ui so that we don't have to open up the javascript console for our demo otherwise we're going to call stripe.confirmfpx payment this is a method that's exposed by stripe.js and accepts a couple different arguments the first is that clientsecret property for the payment intent that was returned from the server the second is a big options block where we have to specify at a minimum the fpx bank element and a return url here we're going to pass in the payment method object that includes reference to that fpx bank element and we're going to pass some billing details that include the name that we collected from that form we also need to add a return url this is the url to which a customer will be redirected after completing the payment flow on the fpx bank's site let's also grab reference to that name input so that nameinput.value will be the value that was entered into the form now confirm fpx payment might resolve with an error object and if there was an error then we're going to log that out to the terminal all right let's give this a whirl we're going to pick maybank2u and hit pay we're redirected to that test payment page that's returned by stripe and when we click on authorized test payment we're redirected to that return url notice that in the query string for this return url there is a client secret property and the payment intent id that are available we can use that payment intent client secret in combination with our publishable key to re-retrieve the payment intent on the client and display some messages about that so let's go implement a new javascript file called return.js and this will be so just a simple bit of logic that will allow us to add some messages to this messages div with the status and id of that payment intent so when the page fully loads we're going to initialize another instance of the stripe object passing again in our publishable key and we're going to first grab reference to all of those query string parameters and extract the one that we care about which is the payment intent client secret we'll pass that as an argument to retrieve payment intent this is a method again available through stripe.js and that will return a promise that will either resolve with an error or a payment intent object if there's an error we'll log that out to our messages div otherwise we will add a new message which prints out the id and the status of the payment intent if we refresh the page immediately see that our payment intent has succeeded and clicking on the id of the payment intent will bring us directly to the stripe dashboard let's test that payment flow again this time we'll select a different bank and click pay we're again brought to that test payment page and we click authorize test payment once more and we're redirected to our brand new return url and we can see the status of the payment is succeeded let's make one tiny refactor here let's use the fetch api to hit our slash config endpoint to again fetch that publishable key and we'll use the publishable key that is returned from the server when we're constructing our instances of the stripe object this will allow us to roll our publishable key and control that directly from the server this is mostly a best practice when you're working with mobile clients but is also handy when you're working on the web too as a quick recap in fpx.html we added these three javascript files and a payment form where we collected the name of the customer and we added an fpx bank element where we registered that stripe element for listing out all of the banks that were available with fpx then we said when the dom is fully loaded we want to create a new instance of stripe and a new fpx bank element we want to mount it into that container for the fpx bank element and we said when the form is submitted we're going to make a post request to slash create payment intent passing in the payment method type and currency and we're going to use the client secret property that came back from our server to call confirm fpx payment passing in reference to that fpx bank element and the billing details that we collected on the client then we implemented a simple return page where we can use the client secret from the payment intent to re-retrieve the payment intent and display the status and a nice thank you page to the customer at this point you're fully equipped to head out and build a custom form to accept an fpx payment if you're curious about other payment method types head over to the stripe developers youtube channel where we have content showing how to accept a variety of payment method types with several languages and frameworks thank you so much for watching and we'll see you in the
