## Description

Working on some open source contributions to a soon to be released Stripe Sample. This time, we're adding support for Afterpay / Clearpay with a React client.

## Transcript

okay holy smokes i uh i actually thought i was live that whole time so it was like 30 minutes of prep for this so this is what we're going to build today uh so you have we have this new sample this that's coming this new stripe stripe sample that's coming it's called accept a payment and in it you'll see how to implement all different kinds of payment methods and so this is kind of like a sneak peek of the sample what you might get eventually when we s when we uh finally or ultimately get rid of our accept a card payment sample and so what we want to do today is add support for this buy now pay later payment method called after pay clear pay in it we'll have to accept the billing address and the shipping address and when we click pay we'll be redirected to a test payment form where we can actually say okay authorized test payment and then we'll be dropped back into our return where we say okay here's the the return for this after pay clear pay payment and the payment intent for uh for the payment so um let's yeah let's take a look and see how we can do this uh so i'm actually going to delete it so i actually already implemented it so we'll go through and we'll delete the whole thing or we'll implement the entire thing um and so here on this on this uh index page uh app yes um so here in after pay clear pay in order to add after pay clear pay a an actual route that will show some react component um we're going to go create that route now so in let's see let's let's take a little tour let's take a little tour so in index.js we have a very simple method that says when the dom finally loads make a get request to the server to slash config which will respond with just the publishable key take your publishable key and call load stripe which returns a promise and then we can use this promise with the elements provider now the the elements provider is part of react stripe.js and allows us to uh inject this stripe promise so that we can resolve an instance of stripe or an instance of elements inside of our child our children components so here we have app that's implemented if we dig into app this is using like kind of the just a normal react router dom for a browser router and we're going to import the after pay clearpay component from after pay clear pay and if we receive a request to slash after pay clearpay we will just use that component as what we're showing on the page and so we need to implement that component so we can say after pay clearpay.js and inside of here we want to we're going to create a couple components one is going to be the after pay clear pay form component one is going to be after pay clear pay return and one is just going to be a switch between the two and we'll call it after pay clear pay and that's what we'll ultimately return is this one and the after pay clear pay form will be a react component that's responsible for rendering that form that has all the address information the return will be responsible for displaying what happens when you get back from successfully paying so yeah hopefully that works as expected um okay so let's see here after pay clear pay the brand new payment method that's supported by stripe and you can check out the docs here i will drop them in a comment if you want to take a look um and it is a it's it's also so it's a payment method is called after pay but it's also known as clearpay in the uk so it's a payment method it's available in these countries um so we're going to add like a little country drop down so you can pick one of these countries when you're going through the process and this is what it will look like so i've got i've got the server running it's a node server actually before we go too far why don't we take a look at that also so we jump into the server directory and today we're using node but really you can look at any of like these nine um these nine server languages or server implementations so again when you when we receive a get request to slash config we're just rendering back the publishable key from our environment variables and if we receive a post request to create payment intent this is where the juicy stuff happens so the post requests body will include a payment method type that's going to allow us to dynamically create payment intent objects for different payment method types or that can be confirmed with different payment method types and we can't just hard code all of the list of payment method types here because some payment method types only work with specific currencies so from the request body we're going to take in the payment method type in the currency and then we're going to use those to create a payment intent it turns out that so far every single payment method type can be used this way and we're just going to render back the client secret or we're going to render back an error that's the entire server really it's just like those are the only two endpoints we're going to use for this this example in this demo um but we have yes we have that slash config and we have slash create payment intent um and on in our after pay clearpay form component when we handle the submit of that form component we will make a post request to create payment intent we'll take the resulting client secret from that payment intent and then we'll use stripe gs and the injected um yeah the injected stripe instance that we can retrieve with the used stripe hook and then we will confirm that payment intent with confirm after pay clear pay so that is looking good uh okay so cool let's do it um all right what what do we where do we where do we go first where do we go first right so um let's create this after pay clear pay component so const after pay clear pay and this will be we're going to use function components and like that's that's all we're going to use today and so for now i'm actually just going to have this be like return after pay clear pay form initially and then we'll we'll like mess around with it um as we go i think i need to do this maybe i don't know let's see so then i can say like export default with router after pay clear pay and we need to use like um yeah so we need to import some stuff so let me just moment just a moment okie dokie cool uh okay so um right okay so where do we get this with router thing this comes from the react react router doms we're gonna say import uh import with router from react router dom and we also need to import react import react from react we're going to do we're going to use state and use effect also in what we're working on today we also want to import use stripe from at stripe react straight js and we have a tool within this sample for displaying status messages so i'm just going to pull that in it's a status messages component and then we have like a little hook that works with it called use messages and that's just like a local thing status messages all right so um we've got our clearpay form we've got our with router so let's add a const um after pay clear pay form and that's going to be a react component it's not going to take any props or anything right now um yeah might as well make our uh return also okay great and so what is this going to look like well it's going to be a massive form so we're going to have some form with id payment let's see payment form and it'll also have status messages and this is just like again purely for debugging and such and we pass in or this the status messages component that we have that's a helper takes in one prop and that is called messages so we can say const messages and add message is what we get back from the use messages uh hook and then we can do stuff like just call like add message like loading or something and that should render into our form um all right so yeah um okay so after pay clearpay form after pay clearpay form and we want that with router what is this element type is invalid expected a string for built-in components use a class or function but got object uh okay did i not do that export correctly uh alt with router maybe i need to restart this stuff let's see um what is going on here oh i probably spelled something wrong yeah i did status messages uh weird um okay split pain horizontally so we're in accepted payment form client react create ac react create react app npm start re-fire up the server here and okay so now we should be able to go to 3 000 okay after pay clear pay i think that's what is going on here oh maybe this path is okay here we go this is where i spell the wrong status messages there we go okay too many re-renders right okay so we don't actually need to call that in there let's see all right so we've got we've got something or we've got nothing but that's all right h1 is going to be after pay slash clear pay all right cool so we've got at least the base here so uh in this form we want to do something like create two field sets to accept two different kinds of addresses so we want to get the billing address we can use a legend tag billing and we can do the same thing for shipping right so we're gonna have two field sets the billing is going to also fetch the name so this is going to have like name email and then address and then this this the shipping is going to have just name and address and these are required fields in order to use after pay so let's just say actually pull these from after pay clear pay we did we if we've already implemented this in html so i'm just going to grab in fact let's let's just remove um yeah or just grab the entire form from the html example and then we will clean it up okay all right so how do we want to clean this up we want to replace um so everywhere that we see value equals we want to make those something different so let's clear out the values for all of those and um okay okay okay all right so uh we're gonna we're gonna do um we're gonna use state in order to control all of our controls so we're gonna say something like const uh name set name use state uh jenny rosen and then we're gonna do email we'll set email and then we'll call this jenny rosen at example.com so i i feel like i'm going to write these a lot and i don't have any um i don't have any uh vim snippets for this yet so i think it might be a good little detour to go create some bim snippets so javascript dot snippets and let's go to the bottom here and say this snippet is called use and what i wanted to do is i wanted to print out const and then i want to have like a name and we'll say that name is like name and then i want it to have uh something else and that something else is going to be set with name so let's see maybe we say like uh dollar two which is dollar one or like set dollar one or something like that and that's going to be equal to use state and then inside single single is going to be dollar three no dollar three like that i think and then we will put um we should land at the very end i think so let's see views boom name okay so that didn't work as expected because i wanted this to like sort of pre-populate as i was typing so uh if i say name again let's see use boom name no that didn't work use uh oh maybe it needed to be okay let's try that again set dollar one let's see use boom name set or n a okay so you see how that's like n-a-n-a uh set name um okay so it's pretty close why don't we just make it dollar one and then we can actually yeah we'll just we'll just have it rewrite the whole thing that's fine um use uh so like now we wanna use the line one which is going to be set line one and we'll say one two three main street and okay so that works nicely i like that that's fine use line two is set line two and we'll leave that blank we're gonna say city says city san francisco um state set state uh california use postal code set postal code 94111 use country set country and then yeah a u australia it'll be the first of the list and that'll work fine um okay so then what we want to do is why don't we write like just a little um so this is going to be yeah this would be like all the billing info and then we want like all the same stuff for for shipping and for shipping we need all of these so let's just drop that here and then what i want to do is make all those uppercase and then put in shipping [Music] and then uh what we can do is set to set shippings okay so that should be cool um all right so now we need to go through our html elements and update instead of putting value whatever we want it to be value and then curly braces so actually i think we can say like value equals this uh value equals did i just delete them all uh value equals okay okay so we don't want to do them all because we don't want to change these ones but most of them we do so if it has double quotes yeah okay so if we want to replace value equals double quotes with value equals curly braces so that we can just like quickly populate all of these values so this this first one is going to be name the next one is going to be actually yeah before we do that let's make it a little bit more complex so in addition to setting the value with this use state variable we're also going to want to add an on change which is going to be um this thing that's like pretty standard i'm going to call set e dot target dot value um and then it's actually not going to be set it's going to be like set name set something set something but we'll just say set for now and that should give us a ton of pre-populated stuff all right so the value here is going to be name the value here is going to be email the value here is going to be line 1 the value here is going to be line two uh the value here city state i probably could have done this with a a macro but uh it's all good and then for these select boxes you can just set the value equal to country and use the same on change function so that when when the select box is changed this function will be called it'll be past an event where the events target is the select box itself and the value from that box is the option that was selected so we can just call set country like so and i think we're going to need the same thing here oh gosh all right whatever so value equals shipping country and on change is going to be on change is going to be e that goes to set country e.target.value okay uh this one's going to be yeah let's just keep going through setting our values country oh man i'm losing track of everything we've done sorry shipping uh value no shipping line one shipping line two and shipping city and wow working with addresses is kind of a pain shipping state uh what do you what are y'all working on let me know in the chat or in the comments below shipping postal code um yeah curious what you're building and if you're considering using afterpay and if so what your business model is and what it looks like and kind of what you're selling would love to see what you're building or working on or if you're using react we'd love to hear if there's a better way to do this or if you've seen other other patterns like this cool one two all right set city set state set that's funny too cause set state is like a thing in non-hook land right set state or no that is the thing that we imported is that going to mess that up set state uh maybe not oh use state set state is the uh the old school class-based components right all right so set uh line one set line two oh actually these are shipping huh set shipping line one set chipping line two set shipping city set shipping [Music] state shipping postal code and set country all right what do we got what's what's the error here oh wow look at that boom no errors holy smokes okay so let's go make an um make this form submittable on submit handle submit and we'll say handle submit is a function that when called we're going to prevent the defaults it's going to be an async function actually and initially we'll just console.log all of the things so name email line one line two uh city state um postal code country and then all the same things but for shipping so shipping doesn't have an email but it does have all of these others oops refresh the page so then if we click submit here if we look in the console we have an object that was logged out and this is all the data that we just retrieved let's actually change the billing like the name for the person we're going to build to to billy and we'll make them live in reno nevada [Music] 89501 because that's a different place and the country is u.s and yeah we'll leave that the same that's fine just to see like to make sure that our shipping address stuff and our billing address stuff is coming in uh differently so we have our name this is the person who's who's buying it name is jenny and this is where she's at and then we have the shipping info and that all looks fantastic so now we need to take all this data and uh use it to confirm payment that we haven't actually created so first we're going to create the payment intent on the server and we're going to confirm the payment on the client so in order to create it on the server we're just going to call the server endpoint so server.js right so we have that create payment intent endpoint that's going to take in the payment method type in the currency so let's do that first we're going to call we're going to use the fetch api to make an a server side ajax call to create payment intent and we're going to pass in the payment method type as uh after pay clear pay like so in the currency we'll just pass usd for now and um when that's returned we're just gonna deserialize the response as json and let's use async await so we're going to say if there was an error or if there was a client secret we'll handle those okay so then if there was an error we want to uh add a status message so we can do that with um add message add message is error error.message and let's return if that's the case otherwise we want to do something with that payment intent so here we'll call const error payment intent equals await strike.confirm ali or no after pay clear pay payment and the first argument is going to be that client secret that we just got back from the server client secret and then the second argument is going to be a big object with a bunch of options and data so the top the first one we need to pass in is the payment method uh stuff about the payment method we also need to pass in stuff about shipping and we need to pass in a return url the return url is going to come back to um this the url that we're at which i think we can get from like window.location.origin slash after pay clear pay and we're going to pass in the query string of return equals true and this return true is going to allow us to trigger the return component rather than just like triggering this form component now in the payment method itself what do we need to pass here well let's take a let's take a look at the docs real quick so i can remember [Music] um so also in the documentation for accepting a an after pay or clear pay payment here you'll see that when they're creating the payment intent server side they're passing in the shipping address instead of passing it in server side we're only passing the amount currency and payment method type server side and we're going to pass in the shipping info client side so that's going to be just a little bit different from what the docs are doing but i think that's okay so here is all the payment method details that we care about and billing details it's gonna have the email name address and all this stuff so we need um billing details which are gonna have the address which is gonna have line one line two city state country and then postal code is snake case in the api so we've got to pass it in like that and then the billing details also include the name and email so that should give us that should get us pretty far and then shipping we want to pass in line one is shipping line one line two is shipping line two uh city is shipping city state is shipping state country is shipping country postal code is shipping postal code and then we also need a name shipping name uh oh this is all gonna fit under address too i think um okay uh should we give it a whirl oh right okay so we're getting an error here that says uh something about the error okay identifier error has already been declared so it turns out that the error response we get from create payment intent and the error response we get from um from this client-side api call to stripe to confirm the payment both errors are going to be the same shape and so we need to alias then i'm going to call this one back-end error and then we'll just use that here back up back-end error and then this one we'll call the stripe error and okay so if there's a backend error we're going to add a message and then return otherwise we should say like uh add message like payment intent created and so then we're going to try to confirm the payment intent we'll be redirected and if there's an error if there's a stripe error so if stripe error then we want to add message stripe error message and return in that case stripe is not defined uh cool because we need to call use stripe const stripe no stripe equals use stripe maybe uh i can't remember if that needs to be called outside of that or or what okay then the next error we're getting is saying invalid dom property 4 did you mean html4 so when we're working in react we can't use these four the four attribute on labels the whole point of this four attribute is so that you can click on name and it will add focus to the correct input box so the browser doesn't care but i think this is something from react so so we want to change the four attribute to html4 so um i'll just use this find and replace and refresh and that should clear that error uh cool all right let's give it a whirl so we click pay payment intent was created and we were redirected to this test page for after pay clear pay which is allows us to click on this authorized test payment and test out the payment and we're redirected back in the query string we see the id of the payment intent and we see the client secret for the payment intent and we see our return true thing which is great because we need to use that in order to number one we're going to use the we're going to use this return true query string variable to know whether or not we need to um render the return so we're going to say like something like cons query is equal to new url search params for the uh search which used location is a hook that i think comes from where does that come from is that from react router dom um [Music] sure chat and then if query dot get return then we want to be the return one else we want to do this one um i think yeah i turned off prettier because it was like yelling at me about stuff but now i'm wanting it uh okay so we're going to return after pay clear pay uh return if we're if we're coming back and we're landing back here from somewhere else okay so the return basically says like when i if i'm if i'm returning back after successfully paying then we should render a status message that says something like here's the status of the payment intent which we can get by making a client-side api call to stripe to retrieve the payment intent so that is what we're going to do next so here we're going to just say something like use stripe again and we're going to use messages again and add message this comes from our use messages hook above and then we're going to pull out the query string params again which we can do like kind of like this payment intent payment intent client secret but instead of window.location here we want to call use location okay and this is going to be the client secret now and because we want to make an api call to stripe and we don't have like an action that's being taken this is going to require an effect so we're going to use use effect and what is the effect going to be it's going to be a function um i don't know if we need to probably need to pass into stripe or something um and probably some more stuff i don't know we'll see so if there's no stripe then return and we'll do nothing otherwise we want to fetch the payment intent which we can do with like uh error payment intent is equal to await stripe dot retrieve payment intent and we can pass in the client secret that we got from the query string params and if there's an error then we want to like add a message and message [Music] with error.message otherwise we will just say add a message with something like payment for the payment content status and it's let's just give its id payment content.id which again we could we could technically pull from the query string param but uh whatever we'll just use what we got returned from the api um this is cool too because you could show things like the amount that was on the payment intent the currency the payment method types etc etc like when it was when it when it happened and other other things that might be interesting here um okay so what is next what do we want to do well we need to render some stuff back so this is just going to be simple some simple html um we're going to return what are we going to return we're going to return a fragment and an h1 that has like after pay clear pay return and we will just use our status messages um this this same component here the status messages component uh and let's see if we've got anything ah right so we can only use a weight within async functions and there's something about use effect that doesn't allow it to work with async functions so we have to do this little trick where we're like const fetch payment intent is a function there's an async function uh that does all this stuff and then we can just call it we call it like right here fetch payment intent uh so that should that should work i think um let's see oh also this needs to be probably in the list yeah uh there's other things here that we're using though in the use effect that might have changed so i'm thinking like maybe we should pass in add message and the client secret just in case those things change so that we can re-render the page in those cases um it's kind of like like your dependency injection thing in angular where you say like okay if any of these things change then re-render or like re-execute the use effect i think um so oh what's going on here browser is not happy uh oh my gosh i have so much open let me kill some of this on here goodbye goodbye browser tabs goodbye give me my memory back um no maybe come on my server my server crash and burn okay shipping country is assigned a value but is never used payment intent is assigned but never used all right so payment intent where is that assigned and never used probably up here um sure okay so oh cool all right so we've got this is the return this is what it looks like this is when we return back that's what it looks like so let's go through the whole flow we've got our after pay clearpay component here we have the ability to write our own addresses so cool and when we click pay it creates a payment intent the payment intent is returned from the server then we use the client secret to redirect to after pays page in production again this is going to be the actual after pay page if we were to fail the test payment here then the status of the payment intent should be reflected as such here so requires payment method this means we have to like go through the payment flow again for this payment intent which we don't really support restarting with the same payment intent but that's totally fine because you could just create another one and then go through the same process we're creating a payment intent we're redirecting and then we click authorized test payment and we are authorizing and dumped back into after pay clear pay in the return so that's it we have successfully added support for uh after pay clear pay to our stripe sample for accepting a one-time payment again this is a brand new payment method it's only supported in four countries right now but it's exciting and yeah it seems pretty straightforward to integrate uh the only thing that's you that's like unusual or different from other payment methods is that you have to pay you have to pass in the full billing address and shipping address every time that you purchase something which isn't a huge deal so yeah thanks again so much for watching i hope you enjoyed i hope you learned something if not um maybe a little lulled to sleep by watching the editing of lots of form elements for addresses so um yeah cool thanks for hanging around and uh we'll see you next time
