## Transcript

hey what's up welcome back in this episode you're going to learn how to accept a one-time payment using a custom form with the payment element if you're looking for a simpler integration path we have the no code payment links option where you can set up a payment link directly through the dashboard and then share that with your customers through social media email text message Etc alternatively there's another option called stripe checkout this is a a very simple integration that has one API call on the server you redirect your customer to a stripe hosted page but in today's episode we're going to talk about integrating the payment element this allows you to build your own custom hosted form and collect lots of different payment method types so the payment element supports anything from cards all the way to bank accounts you've got support for wallets like Google pay and Apple pay all the way to buy now pay later like a firm and after pay clear pay so it is a great option for building your own custom form to accept a one-time payment so just as a quick roadmap for today we're going to install sample then we're going to go through the dashboard and talk about how you can enable payment methods these are going to be those payment methods that are dynamically rendered into the payment element every time the page loads and then we're going to create a payment intent on the server and use its client secret to render the payment element on the client so that we can collect payment details from the customer it will ultimately submit that payment to stripe and we're going to handle any of those post-processing events we're going to talk about web Hooks and a few other considerations that you might want to think about as you're building out your integration so let's get into it so we're in Visual Studio code if you haven't already head over to the extension gallery and install the strip for vs code extension we're going to use the striper vs code extension today to install a stripe sample so under samples we're going to say start with a stripe sample we're going to search for starter and we're going to use the main integration with an HTML client and we're using PHP on the server today we'll call our sample starter Dash PHP and we can pick where we want this example to be cloned down into hit OK and we're going to open this up in the same window and we should be Off to the Races now with PHP we're going to implement the client a little bit differently than all of the other samples so we can actually delete this client directory and then we can take a look at what's inside of the server directory so it's going to come with a DOT end that should be pre-populated if you've already sort of logged into the stripe CLI and authenticated the striper vs code extension with your stripe account if you haven't then you'll want to go over to dot end and make sure that you've populated these API keys with those keys from your stripe dashboard there is another video on the channel talking about authentication which you can search for and you'll find how to set your API Keys now in this public directory we've already got an index.php file there's actually not any PHP in here yet but this is where we're going to collect our payment details and build our form we've also got this shared.php which is loading all of our dependencies using composer it's also doing some checks on our DOT environment variables and finally it is initializing an instance of the stripe PHP client library that we're going to use to make API calls to stripe now we can actually remove this setup info section and hit save now the web hook Handler is also already sort of pre-configured for us and allows us to just start dropping in event types that we want to listen for and handle and we'll come back to that in the very end so this is the the stripe sample let's also open up the terminal here and install some dependencies we're going to CD into the server directory and say composer install now if you don't already have composer set up you can head over and take a look at the documentation about how to install composer and now we're going to say composer start and this will fire up our PHP server and allow us to receive connections all right now our server is up and running we can come over to the browser and hit refresh at localhost 4242 and we are up and running now from the stripe dashboard we can head over to the settings and to the payment method settings this is where we can manage our payment methods and enable or disable different ways that customers can pay through our payment element so you'll see here that we have cards enabled link Apple pay Google pay several different wallet methods there's lots of different bank redirects these are popular across Europe we also have some buy now pay later payment methods that are enabled finally we even have ACH direct debit as one of the payment methods that customers could use now if we wanted to enable Canadian pre-authorized debits we could click turn on and this would enable us to use Canadian pre-authorized debits as a payment method type inside of our payment flows so this is where we manage our payment methods and these are the payment methods that will be dynamically derived inside of our payment element when we render that and show it to customers so that's how you enable and manage your payment methods instead of needing to deploy any new code you can just come into the dashboard and enable or disable different payment method types alright so here is a high level overview of the process that we're going to implement today when a customer lands on the page our application is going to make an API call to stripe to create a payment intent then that payment intent is going to return back to the client we're going to use that client secret property in order to render the payment element so that's the first step in the first process that we're going to implement today so let's jump back into vs code all right so inside of our index.php file here we're going to open up some PHP script and we're going to say that we want to require the shared PHP thing that's going to initialize and set up our dependencies from composer and also that stripe client because we have The Strife for vs code extension installed we can say stripe payment intent create and hit Tab and that will show us the the default API call that we would need to use in order to create a payment intent now the amount here we're going to just hard code 10.99 this is an integer value in the smallest denomination for a given currency right now the currency is set to USD we could also make this Euros if we wanted but one thing to note is that this amount you can calculate this however you want right now we're hard coding it but you could for instance have a this index.php accept a post request that included for instance maybe a like a product ID that you would then use to look up the product in the database and then pull out the amount the unit amount that you need to charge for that product and then you can pass in that unit amount here while you're creating this payment intent so we're hard coding it today but you could use whatever data that is passed to you in order to calculate this amount one thing you don't want to do is accept a raw integer value from the front end in order to create the payment intent the reason you don't want to do that is a malicious user could potentially modify the HTML or modify the request and pass in whatever amount they want and so it's a best practice to pass in some reference or some identifier to then derive 5 the amount that should be charged instead of hard coding the list of payment method types we're also going to use a different feature here called automatic payment methods so we're going to say automatic payment methods is enabled true this is going to help us by allowing us to derive the payment method types that we want to render in the payment element and those payment method types are the ones we just set up in the stripe dashboard so this API call is going to return a payment intent we're going to use this payment intense client secret down below when we write some JavaScript okay so this is really the server side bit in order to create the payment intent pretty straightforward now there's lots of different options for creating payment intents so head over to the stripe documentation look at the API reference for creating payment intents and you'll be able to see which of those are applicable to your business all right now we want to use this payment intent client side in order to render the payment element so a couple things that we need to do we're going to require some JavaScript I'm going to drop this in right before the closing body tag at the bottom of our HTML file here so the script source of this first one is going to be uh js.stripe.com V3 now we always want to load stripe.js from js.stripe.com we don't want to pre-fetch that or you know we don't want to Cache that anywhere so that we always have the latest version so this is a best practice now we also want to create our own little script tag here that we're going to use in order to mount the payment element so we're going to create a new instance of stripe and this is expecting our publishable key so the publishable key is available in the environment so we're going to pass in this stripe we're going to pass in the stripe purple triple key like so and then we're going to close out our sort of short rendering okay now that we have an instance of stripe what we need to do is create an element screw so we're going to say elements is striped elements now in the past we just called elements and we didn't have any arguments we passed in but now with the payment element we actually want to pass in the client secret for the payment intent that we just created so this is going to be payment intent client secret now this payment intent client secret comes from this payment intent that was just created with the API server side before this front end was rendered now we're going to use the elements group to create a new element called the payment element we're going to say elements.create payment and that will be an element that we can mount into a form so in order to mount this payment element we need to have some HTML set up so let's come up here we're going to say this is called like accept a payment and we need a form so we're going to create a new form here and this is going to be called the payment form inside of our payment form we're going to have a div that's going to be our payment element we're also going to have a button that just says pay and finally we'll have another div here for our error messages anything that fails while we are attempting payment we can render out here okay so now that we have this payment element div inside of our form now we can mount the payment element so now we can say payment element.mount and pass in the CSS selector for the payment element now when we head over and refresh our page we should see the payment element rendered here and we do so this is the the payment element if we wanted to we could go through this process and fill out this this entire form notice there are several different payment method types here these are all enabled through the stripe dashboard if we were to switch this from euros to USD save and refresh the page notice that different payment method types are rendered because depending on the currency some payment method types support certain currencies others will support others so this is how we can initialize and set up the payment element in order to render on our custom form we could also Imagine collecting other details around this having input boxes maybe for you know if we needed to collect information about the customer's size or their birthday or some other information we can build that into our custom form here but the one thing we're not doing yet is handling the submission of the form so let's do that next in order to handle submissions of this form we want to do that with JavaScript so that we can submit payment client-side back to Stripes we're going to grab reference to the form using document.getelementbyid passing in payment form as the identifier then we're going to add an event listener on submit so that each time the form is submitted we're going to actually prevent default for the event so the form is not fully submitted back to the server instead we want to handle this client side and we're going to call stripe.confirm payment passing in this options block now the first thing we want to include in the options block is reference to this elements group so we're going to drop in the elements we also want to drop in a confirm params option that is going to include a return URL this is the URL to which the customer is going to be redirected after they go through the payment flow we're just going to pull this off the window so window.location.href and we're going to split on the question mark and that'll allow us to remove any query string arguments and then we're just going to add complete.php that'll be where we redirect the customer to this newcomplete.php script that we haven't actually written yet now confirm payment returns a promise and that might resolve with an object that has an error property on it and if that's the case then we want to use this error messages div to render back those error messages so we're going to say if there was an error then populate that message as div we're going to say messages is document.getelement by ID and we'll set messages inner text equal to error.message all right let's take this thing for a spin so we refresh the page we're going to enter in this special 4242 card number it's just all four two four twos and a future expiration any CBC and any zip code and we're going to click on pay now that is going to again submit the payment client side all the payment details are going client-side to stripe then we're redirected to this complete dot PHP file notice that there is a query string parameter that includes the ID of the payment intent it also includes the client secret for the payment intent so we can re we can either re-retrieve the payment intent server side or client side in order to display those details so let's create a new file and talk about how we're going to build that completion page next okay so we're going to create a new file here we're going to save it and call it complete.php and this again is going to have reference to our our shared script so that we can load the API keys and dependencies so we're going to require share.php and then we're going to make an API call to strive to pull back our payment intent that we just went through the payment flow for so we're going to say stripe payment intents retrieve and we're going to pass in the ID of the payment intent that is again included inside of the query string params Under payment intent let's just grab some of this HTML so that we can reuse it and we'll drop it in here this will allow us to have just a little bit of style already okay we'll call this page complete and for now we'll just put a pre-tag here that will render out the Json in code for the payment intent so that we can see it and it looks nice on the page we can see all of the Json for that payment intent so we'll refresh the page now and now we are seeing this completion page with all of the data about the payment intent and at the very bottom we can see the status of the payment intent is succeeded if you are using some of the delayed payment method types like ACH or another one of the bank debit types it's possible that it takes a couple of days for that payment to clear so this might be in a pending State there's several different reasons why you might want to display the status and maybe the amount you can pull a lot of different information off of this payment intent to tell your customer what their order number is and details about the payment intent so that is how we can build a completion page this return URL or completion page is a great place to confirm with the customer and let them know that their payment has gone through successfully but it's not a good place to handle any fulfillment automations it's possible that between submitting payments successfully to stripe and redirecting to this page the customer's internet went down their Network went down or their computer died there's several different reasons why they might not actually make it to this page and your server might not receive the request for this complete.php page it's that reason that we want to use web hooks for all fulfillment web hooks are superior because if your server is down for some reason stripe will retry sending you a notification about this event for up to three days with exponential back off so let's take a look at our web hook Handler inside of our public directory we've already got this set up now we are listening for the payment intent that succeeded webhook event type you'll also want to listen to payment intent.pending or payment intent.payment failed there's several different event types that you could listen for you can head over to the stripe documentation for the entire list but what I wanted to do is quickly run through how you might test your web hook endpoint using the strifer vs code extension with our our setup today so what we want to do is we're going to go to the straightfor vs code extension we're going to say we want to forward events to localhost 4242 webhook dot PHP this is the route where our events should be sent now there's going to be two URLs we need to enter this is the one for account events this is for the events that are firing on our own account the second one is for connect events which we're not actually handling today but we'll drop this in there connect is when you're building a Marketplace or a platform for facilitating payment on behalf of other accounts so we've got a new listener set up here so let's open up our terminal and we can see the output for stripe listen down here including the web hook signing secret now every time you create a new webhook endpoint you're going to get a different web hook signing secret this is the secret that you're going to include inside of your web hook construct event call in order to confirm that the payload did in fact come from stripe this prevents people from maliciously attempting to send payloads directly to your webbook endpoint without your permission and sort of maliciously triggering fulfillment so we're going to use this webhook signing secret to confirm that the event came from stripe Now by setting up this listener we now have this direct connection and events will fire on our stripe account and be forwarded to this local machine so what we can do is I'm going to navigate back to the root route and when we hit enter you'll notice that a payment intent is created that's because we're creating that payment intent on the page load for index.php so that we can render the payment element so this is the first event that we are handling is this payment intent created all right so we're going to enter in a card number here CBC and a zip code and hit pay and when we're redirected to the completion page we can see several different events fired on our account including this payment intent dot succeededevent which was forwarded to our server as we are handling the payment intent succeeded event we are logging out that payment was received and we can see that inside of our logs here so we can see that payment was received and if we wanted to this is where we might pull from inventory print shipping labels Mark the customer as booked for some event or call or something so this is how you would actually automate fulfillment again not based on the complete.php but instead using this web hook Handler now another important thing to mention is that when you go to production you won't use the strifer vs code extension or the stripe CLI to forward events instead you'll take your publicly accessible webhook endpoint URL you'll go to the stripe dashboard drop that in so that events are forwarded to your public endpoint you might be wondering how to test out your integration well over in the documentation for accepting a payment you can drill down into the test integration section and for each of the different payment method families between cards wallets Bank redirects Etc there are several different things that will allow you to test different scenarios so for instance we can grab this card this test card that ends in 3155 and we can use that as one of our test cards inside of the payment element and you'll notice that as we go through the payment flow here this will trigger a secure customer authentication payment flow so this is going to pop up a modal and in production this modal would contain a bank account 2fa or sort of like a one-time code or some way to verify that the customer is who they say they are and that they are allowed to authenticate this payment so that's one way that you can test sort of 3D secure and secure customer authentication is with that special card number there's a bunch of different card numbers and test strings that you can use use for different bank accounts so if you're ready to test your integration head over to the docs and look at those test strings another thing worth noting is in the documentation there are some optional steps depending on specific payment method types or QR code based payment methods these might require that you pass additional details when creating the payment intent or they might have other considerations like with Apple pay you'll need to go into the dashboard and make sure that you have an Apple pay domain set up and verified so just to review the entire flow the customer lands on the page and we use any information from that page to create a payment intent using the API and then when we return that payment intents client secret to the client we use that to build out a payment element on our custom form that's where customers enter their billing details and then we can submit that payment directly to stripe client side and then the customer is redirected to a return URL where we display this return status or this success status completion status and finally we're handling fulfillment with our web hook that's where we're actually pulling from inventory and printing shipping labels and doing all those things that we might do when someone buys something from us thank you so much for watching and we'll see in the next one
