episode you'll learn how to implement a react client to accept a one-time fpx payment with a custom form so fpx or financial process exchange 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 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 we're going to say that you already have a back end set up to create payment intents and you want to add support for accepting those fpx payments on the front end if you don't already have a server implemented head over and take a look at one of those example integrations in our officially supported server languages those will be linked down in the description also before we get too far if you're not using react we have an example for how to accept fpx payments using just vanilla javascript and html that'll also be linked down in the description all right let's get started so our server is up and running here and it has two endpoints 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 the payment method type and the currency as arguments here we're going to pass fpx as the payment method type and malaysian ringgits as the currency now this endpoint is going to create a payment intent on the server and return just its client secret property which we're going to use to confirm the payment on the client all right let's take a look at what we've already got going on this client is based on the create react app base template in index.js first we'll fetch that slash config route so that we have access to our publishable key then we're going to call load stripe passing in our publishable key which is going to return a promise that will resolve with an instance of stripe load stripe is available through the stripe.js npm module and this will install stripe.js on the page then we're using the elements provider to wrap our entire app we're passing in the stripe prop which is either that promise or it can be an instance of a stripe object we wrap the entire app so that we have access to elements and to the instance of the stripe object inside of our child components let's head over and take a look at app.js here we're rendering a number of routes using react router dom let's add a brand new route for slash fpx that will render the fpx payment form we'll need to import that fpx component which is not yet defined so we're going to go head over and implement fpx.js in just a moment so fpx.js will implement a functional react component we'll export the default with router so that if we need to we can redirect from this component we'll install some dependencies if we click on fpx and browse to that route you'll notice that we get an error back that's because we're not actually returning anything so let's add some html return from our fpx form component that will include our payment form so we're going to add a brand new form with a pay button now we'll also collect the name of the customer we'll also add another label and this label will be for the fpx bank element next we'll add the fpx bank element component and pass in an options prop fpx bank element is a react component that's available in react stripe.js it's it expects a number of options including the account holder type next we're going to use state in order to manage the state of that name input all right now our form is rendering correctly on the right-hand side we can see this list of banks but when we click pay nothing actually happens because we haven't wired up a submit handler for this form so let's give it an id so that it will accept some of our css classes and we'll add an on submit handler now when the form is submitted we want to do two things first we're going to create a payment intent on the server and second we're going to confirm that payment intent on the client here we'll use the built-in fetch api to make a post request to slash create payment intent this returns a promise that will resolve with either an error property or the client secret for the newly created payment intent recall that we also need to pass in the payment method type and the currency this is just for demonstration purposes and to align with our back-end implementation but in practice you could hard code the payment method types and currencies on the server and not pass those in from the client if our request resulted in some error we will add a message that will log out the message that we received from our backend and return now this add message method is a helper that we're going to import from another component here we'll import the status messages component and the use messages hook status messages is a helper file that we've already written that will iterate over a list of strings and print them out in a terminal-like window in the ui so that we don't have to open the dev console as we go this is all purely for demonstration we'll use this use messages hook to create a messages state variable and we'll have an add message method here that will allow us to add messages to the status messages div as we go along all right next up we need to confirm the payment intent on the client stripe exposes a method called confirm fpx payment this takes in a client secret and an options block in the options block we can pass in a number of different arguments like the payment method type billing details and a return url to which the customer will be redirected after visiting the fpx payment flow notice here that we're using the elements object to retrieve the element given the class type for that fpx bank element react stripe gs exposes two helpful hooks when working with stripe one is called use stripe and the other is use elements these will return instances of the stripe object or the elements object because we wrapped our app in that elements provider back in index.js when the form is first submitted we want to check to make sure that both stripe and elements are loaded alright so this confirm fpx payment method returns a promise that might resolve with an error property and if there's an error again we will log that out to the status messages div all right let's take the demo for a spin we will select a bank from the drop down and click pay in test mode we're brought to the test payment page where we can click on authorized test payment now this brings us right back to the url we specified as the return url when calling confirm fpx payment in the query string we'll see return true as one of the query string parameters but we'll also see the id of the payment intent and its client secret so we can use the payment intent's client secret to show a thank you page and display the status of the payment directly to the customer so in order to render that thank you page we're going to create a brand new component that we will optionally render when we're coming back to that return url this will be another functional component that we'll call fpx return and we'll say thank you for your payment and we'll add another status messages div there and inside of the fpx return component we can again use the use messages hook so that we can render those messages directly into the status messages div in order to re-retrieve the payment intent we need its client secret so let's extract that from the query string params we'll use react's use effect in order to re-retrieve that payment intent based on the client secret so first we're going to say that this use effect hook depends on the client secret property and inside of here we'll call stripe.retrieve passing in that client secret that was in the query string parameter retrievepaymentintent returns a promise that will resolve with an instance of the the payment intent and then we can use that to log out a brand new message to our uh status messages div with the id and status of the payment intent again inside of our use effect hook we want to make sure that stripe is loaded so we'll say that that is also a dependency and we'll check to make sure that it's loaded and again we can retrieve reference to the stripe object using the use stripe hook before we get too far we need to import use effect from react we also need to import use location from react router dom in order to render that fpx return component we're going to build a new component that is a little bit higher level called fpx and this will check to see if there is a return string in the query string parameters and if so it'll render the fpx return component otherwise it'll render our fpx form component now we can export our default as this higher order fpx component and go through our payment flow once more so we'll pick a bank from the drop down and click pay we're redirected to the test payment page where we can click authorize test payment and again we're redirected back to our return url and now we can see the id and status of the payment intent if we click on the id we're brought to the stripe dashboard where we can see the payment was successful and it was collected indeed with fpx payment all right so as a quick recap inside of index.js we fetched the publishable key and created a stripe promise then we wrapped our entire app in this elements provider passing down that stripe promise then inside of app.js we created this new fpx component and added a route to fpx that will render that component and then inside of fpx we write we created three new components fpx form fpx return and fpx the fpx form component created a payment form collecting the customer's name and their fpx bank that they would like to use we also handled the submission of that form by saying let's first we'll create a payment intent on the server passing in the payment method type and currency then we'll use the client secret that was returned to call confirm fpx payment which will redirect us to the fpx payment flow and ultimately we created this return component that thanked the customer for their payment and displayed some status messages about the payment in the ui at this point you're fully equipped to head out and build an fpx payment flow to collect a one-time payment using react thank you so much for watching and we'll see in the next one --- [Back to all videos](https://www.cjav.dev/videos) ---
