## 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 then 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 foreign we're going to start from a stripe sample today so that we don't have to write a bunch of boilerplate for today's demo if you haven't already you can head over to the extension gallery and install the striper vs code extension one of the handy Tools in here is to start with a stripe sample so here we're going to click on start with a sample and start with the starter sample and we're going to use the main integration today HTML on the client Java spark on the server and we're going to call this starter Java that's going to download and clone a sample locally it'll also use the stripe for vs code extension to set our API keys in an environment variable so this is all ready for us to go all right let's take a look so in the server directory you'll notice there is this Dot N file at the root of the server directory this already has our API Keys set that's because the strip for vs code extension is using the stripe CLI under the hood and we have already authenticated with the stripe CLI now if you don't have API Keys set here you'll want to make sure that there is a DOT end file in the root of your server directory we also have a client directory here that's going to have our HTML and JavaScript for now we just have this very simple JavaScript page now if we want to start up the server there are instructions in the readme at the very bottom for how to fire this up we're going to build the package with Maven package so we can open up the terminal here CD into the server and say Maven package and that's going to install our dependencies and build the jar file that we're going to use to run our servers and then we can say fire up the server with this command and now we are running on localhost 4242. okay so let's jump into the server directory and take a look at what we've got going on here so there is a simple server.java file and in here there's going to be a couple different things that we want to take a look at all right we'll start off at the very top of the server class now this create payment request class and the create payment response class are two helpers that we're not going to use today there's also this config response and failure response classes these are all helpful classes for serializing and deserializing Json as we head down into the main function you'll notice that we have a couple of routes already defined there's one called slash config this is for fetching our publishable API key it is a best practice to fetch your publishable key from the server instead of hard coding on the client just in case you need to roll that key for any reason especially if you're using mobile clients where the mobile client might be you know installed one time and not updated for years if you have to roll your publishable key you don't want that to impact your end users now we've also got a create payment intent endpoint as part of the sample we're actually just going to remove that entire endpoint here because we're going to re-implement that as part of today's demo you also see a web hook Handler this is a route for processing and handling web hook events and we're going to use this and I'll talk about how to test your web hook endpoint in order to process the payment intent succeeded event for fulfillment and we'll do that a little bit later all right so this is the skeleton that we're going to start with our page is up and running we've got our server up and running so let's talk about how we might enable some payment methods so that we can dynamically render those in the payment element on our custom form 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 here's an overview of the payment flow we're going to implement today when a customer lands on our page we're going to make an Ajax request from the client back to our server maybe that will include any in order information or a product that they want to purchase and then from our server we're going to calculate the amount that we want to charge and make an API call to stripe to create a payment intent when stripe Returns the payment intent object from the API we're going to pull off the client secret property from that payment intent and hand that off to our client so that we can render the payment element on the front end so let's go over to the server and implement this step here where we're going to create the payment intent so here on the server we're going to make a post route for create payment intent this is going to take in the request and the response we're going to respond with Json so I'm going to say response.type is application Json next we need to actually make the API call to create our payment intent here so we're going to say payment intent create params is going to be built with a a builder here from this payment intent create params Builder and we say dot Builder and ultimately dot build and we need to set a couple different values here so we're going to set the amount and this is going to take in a long in our case we're going to just charge 1099. now if you wanted to again you could pass in some arguments from the client maybe the ID of the product and then you can look up the product in the database to derive the amount that you want to actually charge so we're going to pass that in as the the hard-coded amount that we're going to charge today we also want to set the currency so in this case we're going to set it to USD and finally we want to configure the payment intent so that when we use its client secret on the front end it will derive the payment method types that are available so whether it's cards or bank accounts based on the configuration that we have in the stripe dashboard that way we don't have to deploy new code to enable or disable different payment method types the way we do that is by saying sent automatic payment methods and we're going to pass in another argument here that's going to enable those payment methods so we're going to say payment intent uh create params.automatic payment methods dot Builder dot build and in this case we're going to call set enabled to true that's going to enable our automatic payment methods so at this point we've constructed some params that we then want to send to the stripe API the way we do that is by calling the payment intent.create method and passing in those params that's going to give us back a payment intent object that we can store off here in an intent variable and we want to again pull off the client secret property from this intent and render that back as Json so I'm going to say return gson.2 Json and we're going to pass in some like client secret response object that we will build here in a second just using a simple hash map this is going to be a hash map from string to string and we're going to call it that client Secret response and it'll just be a simple new hash map now the one key we want to set on this is based on the intense client secret so we're going to say client secret response.put client secret like that Camel case and then we're going to pull off the intent client get client Secret and we should be good to go all right so we need to restart our server so we're going to go back into the server directory and I'm going to combine our packaging and our starting of the server into one command and hit enter and now what we should be able to do is create another terminal here and say curl Dash X post to localhost 4242 create payment intent this is going to send a post request and fire off this endpoint and we get back our client secret our Json that has the client secret property embedded in it so at this point we're done creating the payment intent on the server now there's a bunch of different arguments that you could pass in when you're configuring the params for that API call so head over to the API reference and take a look at the docs about all the different ways that you can configure this for your use case all right now that we have our client secret property let's jump over to the front end and add a form to our page so that we can collect payment so right now on our index.html page we have a script tag that is loading stripe.js from js.stripe.com we've also got just a little bit of HTML here so we're going to change this to accept a payment and we're going to add a form here and it doesn't need an action because we're going to handle submission of this form client size we're going to call this our payment form and inside of our payment form we're gonna have a couple divs and a button so the first div is going to be our payment element and our second div is going to be our error messages finally we're going to have a button that will just say pay now the first div here for the payment element this is where we're going to mount the element into so we're going to use JavaScript on the front end fetch that client secret property from the server and then we're going to mount that into this div here so let's create a new Javascript file here we're going to call it payment.js and we're going to load that on our index page here we're going to say just dot slash payment and now we'll Implement our payment.js file so when the page is fully loaded we want to do a couple things first we're going to fetch the publishable key from the server then we're going to fetch the client secret property for the payment intent and then we'll Mount our elements okay so to fetch our publishable key from the server we're going to use the fetch API to make a get request to slash config now this method is going to return a promise that will resolve with a response object that has a method on it called Json which will also return a promise so we're going to await that and this is going to give us back our publishable key we're going to use that publishable key to initialize a new instance of stripe and that will allow us to construct some elements and use the stripe API client side from here forward now we want to fetch the client secret property for that payment intent so we're going to make the call a fetch call to create payment intent and this is going to take in an object because we need to specify the method as post request we're also going to pass in some headers saying that we want back a content type of application Json and here's where you would specify any body if you wanted to pass in some some arguments from the client maybe including like a product ID or something that you're going to use in order to derive which amount you want to charge in the demo today we're not actually passing anything from the front end and we're just hard coding that 1099 amount this fetch method is going to return a promise it's going to resolve with an object again a response object that has this Json property on it so we're going to await this again and this time we're going to pull off the client secret property now we're going to use this client secret to construct our elements so we say const elements is strive.elements now in the past you would just call stripe.elements and that would give you back an elements group that could create you know one of the classic card elements but in the case of the payment element we want to construct our elements group passing in the client secret property from the payment intent we just created server side this will allow us to derive which payment method types we should display based on the currency of the payment intent and the payment method types that are enabled in the stripe dashboard all right let's make a payment element we're going to call elements.create and pass in the string payment that's going to create a payment element for us and now we can finally Mount the payment element onto our form by passing in the CSS selector for that div that we created earlier so at this point if we were to refresh our page here we should see our pay button we also see the payment element rendered out so that's great now we're able to sort of collect payment details on the client but if we were to push the pay button here this is not actually going to submit the payment to stripe that is going to be in the next step here next we're going to grab reference to our form element using document.getelementbyid passing in the ID of the payment form now when the form is submitted we're going to first prevent the default on the event so that it does not cause a full page refresh then we're going to submit the payment to stripe so on stripe.js on this stripe object we can call confirm payment and we can pass in this object that has reference to the elements group that we created earlier and it also has some arguments here that are going to configure what happens when we confirm payments so we're going to pass in some confirmed params inside of confirm params we want to include a return URL and this is where the customer will be redirected after they complete the payment flow this is going to be window.location.8 for the demo today we're going to keep it really simple we're going to redirect to another HTML page that's called complete.html so we're going to say window.location.href that's we'll split on the question mark and then just grab the first part of that and add on the complete.html as our route now confirm payment might return a promise in the case that payment failed and that'll have an error property on it so we can check to see if there was an error and if there was then we want to log that out in our messages div that we created earlier so again we're going to grab reference to the messages div with document.getelement by ID and we're going to pass in error messages and we're going to populate those messages with the error response objects we're going to say error.message all right now we're ready to take this for a spin we're going to refresh our page so that we have that new JavaScript and we're ready to walk through the flow you also notice that these different payment method types are rendering based on the currency and also the settings that I have enabled in the stripe dashboard so here we can pass in a test card number this is the 4242 number which will result in a successful payment we can click on pay and were redirected to a new page at the top here if you zoom in you can see that this is going to the complete.html route But it includes a couple things in the query string parameter namely it has a payment intent id and a payment intent client secret okay so let's go implement complete.html so let's create a new HTML file here we're going to call it complete.html we're going to put this inside of the client and I'm actually just going to grab most of what we already had in index.html to get us started so instead of payment.js we're going to create another file called complete.js and we're going to have just a completion page here uh clean this up a little bit and now we'll also add a pre-tag here that's going to have the ID of payment intent and that'll give us a place to render out the Json for the payment intent so we can look at its status and all the attributes that we might use to build our own custom sort of like confirmation page all right let's make a new file for that complete.js and again once the document is fully loaded we're going to fetch the publishable key and then we're going to render the payment intent okay so let's grab our client our publishable key and construct an instance of the stripe object we also want to grab that client secret property off the query string parameter so we're going to create a new params object here from URL search params passing in window.location.href and now we can call params.get and pass in payment intent client secret all lower case snake case and now we can use stripe.js client side to re-retrieve the payment intent so stripe dot retrieve payment intent takes in a client secret property this again returns a promise that once it resolves it'll have this payment intent property on it and that payment intent will have all of the Json for the object so again we're going to render this out into the the page we can say document dot get element by ID payment intent dot enter text is going to be equal to well stringify our payment intent and null two just to make it look nice so if we refresh our page here now we see this complete.html page and we're seeing the contents of our payment intent we can see the status is succeeded here at the bottom so we know that our payment has successfully gone through we can also tell a bunch of information about the payment intent including what payment method types might have been presented and any other details we don't want to use this completion page as the signal for when we should complete our fulfillment of the order instead we want to use web hooks so web hooks are a way to be notified from stripe when events happen on your stripe account the benefit of web hooks over using this completion page is if someone closes their browser or maybe their internet dies or their battery dies on their phone there's a possibility that they won't be redirected to this completion page although they may have completed payment and in that case we still want to make sure that we're fulfilling the order with a web hook Handler stripe will continue retrying to deliver a webhook event notification for up to three days with exponential back off if the first delivery is not successful so we know that a webhook endpoint is much more reliable because there are built-in retries so if we look at our webhook endpoint here you'll notice that we are parsing the incoming request body from stripe or constructing an event and then we're going to look at the event type and based on the type of the event we can create this switch statement where depending on the event type we can perform different actions fulfill orders pull from inventory print shipping labels Etc right now we're just printing out that we received payment here this is going to be printed out to the server logs now I wanted to show that there's this tool inside of the striper vs code extension where we can forward events to a local running server so we're going to say we want to forward events to localhost 4242 webhook now this dialog here is going to ask us for two different URLs the first is for account events those are events that are firing on our own account we haven't talked about stripe connect at all that's a tool for building Platforms in marketplaces but this second web hook endpoint that it's expecting is for connect events so we're going to fire this up and this will start a new listener on our stripe account and as events fire they're going to be logged out here to our stripe listener they're also going to be forwarded into our server so we're going to take a look at this listen output as we reload the page because recall that as soon as we reload our root route that's going to make an API call to stripe to create a payment intent and here we can see that the paymentintent.created event fired it was delivered to our web hook Handler and the server responded with a 400 status code that's because we're not currently handling that event type that's an unexpected event type okay so now if we go through our payment flow one more time we can see that we received this payment intent succeeded event and responded with a 200 status code from our server if we go over to the server logs we can see that this payment intent received or this payment received output message was indeed logged to the console again this is where you would handle fulfillment of those payments 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 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 foreign [Music]
