## Transcript

in this episode you'll learn how to implement a react client to accept a one-time grab pay payment with a custom form so grab pay is a payment method developed by grab grabpay is a digital wallet customers maintain a balance in their wallets that they pay out with so in order to pay with grab pay customers are redirected to the grab pays website where they have to authenticate the transaction using a one-time password after authenticating customers will be redirected back to your site in this example we're going to assume that you already have a server set up for creating payment intents and you want to add support for confirming these grab pay payments on the client if you don't already have a server implemented you can head over to one of the integration examples that we have for one of the officially supported server languages those are linked down in the description also before we get too far if you're not using react we also have episodes about grab pay and accepting grad pay payments using vanilla js and html those are also going to be linked down in the description all right let's get started our server is up and running it has two endpoints we'll interact with today one is slash config for fetching publishable keys and one is slash create payment intent now this endpoint accepts a payment method type and a currency as arguments here we're going to pass grab pay as our payment method type and malaysian ringgits as our currency this endpoint is going to create a payment intent on the server and return just its client secret property which we'll use to confirm the payment on the client so let's take a look at what we already have this client directory is created with the create react app base we'll start off in index.js first we're fetching that publishable key using the config endpoint next we're calling load stripe passing in that publishable key load stripe is available in the stripe.js npm module and will load the stripe.js tag on every single page here we're using the elements provider passing in that stripe promise as our stripe prop this elements provider is wrapping the entire app so that we have access to both stripe elements and to stripe.js inside of child's components now let's head over and take a look at appjs so inside of app.js we are using react router dom to define some routes we'll create a brand new route grab pay where we'll render our grab pay payment form we're going to import grab pay from slash grab pay which doesn't exist yet and we'll have to head over and create grabpay.js where we'll implement our grab pay form we're going to export default with router so that if we need to we can redirect inside of this component we'll also need to import with router from react router dom and we'll need to import react start off with a basic form component that will have a pay button and we'll collect the name from the customer here in our name component we're going to use the standard use state state management so that we can two-way bind our name using the name value and set name next we're also going to import status messages which is a component that we can use to render some messages to the ui instead of needing to constantly open up the terminal status messages will loop over a list of strings and print those out to the console we also have this helpful use messages hook we can create a messages state variable and an add message helper function that we can call to add messages to that div now at this point our form is not handling submit so let's add a brand new submit handler where we're going 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 on the client now to create the payment inside the server we're going to use the fetch api to send a post request to slash create payment intent this will return a promise that will resolve with either an error or the client secret for that newly created payment intent recall that this endpoint accepts two arguments we're going to pass the payment method type and the currency now in practice you would very likely hard code the payment method types you support on the server and the currencies that you support on the server here we're passing those in so that we can demonstrate the widest variety of payment method type and currency combinations now if something failed while we were creating that payment intent we'll log out that back-end error to our status messages div otherwise we'll log out that the payment intent was created next we need to call stripe dot confirm grab pay payment this is a method that's available on stripe.js and we can pass in as the first argument the client secret property for that payment intent that was just returned from the server we'll also pass in some billing details including the name of the customer and a return url this return url will be the url to which the customer is redirected after they complete their payment flow on the grab pay site notice our error is saying that stripe isn't loaded we need to use the used stripe hook from react stripe js and ensure that stripe is loaded when the form is submitted if stripe is not loaded we'll just log out a simple message to our messages div here and return early confirm grab pay payment will return a promise that promise might resolve with an error property and if there's an error we'll again log that status message out to our div all right let's take this for a spin so we click on pay and we're brought to the test payment page where we can then click on authorized test payment and we're redirected back to our fpx payment flow notice here in the query string that we have access to the id for the payment intent and the client secret property for the payment intent we can use the payment intent's client secret in combination with our publishable key to re-retrieve the payment intent on the client and display the status of the payment to the customer so now we'll implement a brand new component that will be sort of the thank you page or the return page for the grab pay payment we'll call this component grab pay return and this will be a very simple component with a header and the status messages div where we can add some messages about the payment intent that was created now the goal here is to refetch that payment intent with a client secret from those query string parameters we need to use the use effect hook because we're going to make an asynchronous call out to stripe to re-retrieve that payment intent we'll extract the query string parameters from the location search bar and we want specifically that payment intent client secret now we can call stripe.retrievepayment passing in the client secret property for that payment intent that'll return a promise that will resolve with an payment intent object that we can then use to add a brand new message to our status messages div before we get too far we need to also call use stripe so that we have access to that stripe object and we'll pass that in again as a dependency and make sure that it's loaded before we call retrieve payment now in order for us to use this component on the return page we need to create a higher order component called grab pay that will check to see if there is a return keyword in the query string parameters and if so it will render the return component otherwise it will render the form component now we'll return with router passing in this higher order component where now we can see our return flow when we get back to the return page so let's take this for a spin again we'll click on pay we're redirected to the test payment page where we can click on authorized test payment authorized test payment will bring us back to our return page we can now see the the status of the payment intent and its id and if we click on its id we're brought into the stripe dashboard where we can confirm that this payment was collected with grab pay and we see that the status is now succeeded and the amount for the payment and several other details all right so as a quick recap in index.js we loaded our publishable key and an instance of stripe we wrapped our entire app with this elements provider then we went over to app.js and added a new route for grab pay where we can render this grab pay component in our grab pay form component we added a new form where we collected the name for the customer and when we handle submit of that form we create a payment intent on the server by sending a post request to create payment intent passing in grab pay and malaysian ringgits then we confirm that payment intent by calling confirm grab pay payment passing in the payment intent client secret that was returned from the server in the previous step we also pass in some payment method details and a return url and when the customer finishes their payment on grabpay's site we're redirected back to this return url where we can then use the payment intents client secret to re-retrieve the payment intent and display its status to the customer again our higher level grab pay component is checking to see if it has that return keyword in the url and if so it renders the return component otherwise it renders the form component at this point you are fully equipped to head out and build a react-based payment form to collect a one-time grab pay payment thank you so much for watching and we'll see you in the next one
