how to set up a web hook handler for stripe web hooks in a remix application using one of those remix actions if you haven't already seen our video all about getting set up with remix and stripe for accepting a one-time payment head over and take a look at that video we'll link down in the description you should also see a pop-up over here somewhere and in this video we're going to talk about just building out that web hook handler [Music] so i've got the the dev server running here what we're going to do is pop open our application here go to routes and add webhooks.tsx now inside of here what we want to do is create const action and that is going to be a function that is going to receive the request and then we can do some things with a request that's coming in recall that a web hook is sort of like a telephone where you're going to receive a notification when something happens so in this case when a payment intent is created or succeeds or really any other event happens on your stripe account you can action that and you can be notified about that and automate some things directly inside of this remix action so for now we'll just console.log request.json so we'll just log out the json and that returns a promise so we need to await that and we'll also return just some empty objects here down at the bottom now in order to test web hooks oftentimes you need some way to connect that third-party application to your locally running server maybe you're using ngrok you might be tunneling you could somehow put this application on the internet so you can receive those web book notifications in today's episode we're going to use the stripe cli i'm going to say stripe listen forward to local host 3000 web hooks and that will form a direct connection between my stripe account and my locally running server if you haven't already watched the stripe cli episode head over and take a look at that one also all right so you'll also notice that we have a signing secret that was rendered out here we're going to come back and talk about how to verify those web hook signatures in just a minute but now we have this action set up and it's running at this web hooks endpoint if we go through our process for buying a book as soon as we click on buy a book a brand new payment intent is created as part of rendering that page and we see all of this event data that came in directly in the server logs because recall that we're console logging the json for that event right okay so now this all of this data comes in we see that the type of the event was payment intent created we can see that the status of the payment intent is currently requires payment method that's because we actually haven't filled in the form yet but if we were to go through the process of filling in this form we would see that we're going to get another event type that is going to be sent to us so if we click pay then as that payment is being confirmed we're going to have a couple other events fire charge succeeded and a few other things that are going to fire so here we have this charge succeeded we're going to see another a payment intent succeeded event so these are all the event types that we might want to use to automate fulfillment of our you know uh the goods and services that we're going to sell or maybe provision access to some digital uh some digital thing that we're selling so let's go back over to our application here because right now it's not actually secure right because this is just receiving any old json request that is posted to our webhook endpoint so for instance if we said curl dash x post to local host 3000 web hook at this point anyone could just create some web hook data my web hook data and post it to my end point blah okay so if i send that uh oh web hooks plural so if i send that i got back this empty object and also in the server log you'll see that we logged out the json that was sent to us so instead of trusting any old post request that comes in what we want to do is verify those webhook signing secrets and we can do that using this i'm sorry we want to verify those signatures on the web hook payload so we're going to use this webhook signing secret as our our signing secret just drop that in here in practice you might want to store this in an environment variable which you could do um we're also going to grab off the signature header from the request so we're going to say this is the signature is going to be request.headers stripe signature and we're also going to create an object called an event that we're going to set as part of this next part of the process so we're going to say that the event is equal to stripe.webhooks.constructevent now this takes in three different arguments we need to pass in the payload that's going to be the raw request body and we'll talk about how to get access to that we also need to pass in that webhook sign or the webhook signature that was in the payload so that's going to be that header that includes the signature but this construct event method might raise an exception so we want to wrap this whole thing in a try uh catch block that's going to give us back an error if it does fail and if it does fail what we want to do is we want to return back a response with a 400 saying you know this failed because we weren't able to verify the the signing secret so we're going to say return new response and the response is going to have like our message inside of it if you want you can get fancy and put your own custom messages in there we can say the status in this case is 400 and that should be good for rendering back now otherwise if we did uh if we did successfully receive an event then we want to sort of switch on the event type so we can say like if the event.type is payment intent dot succeeded then what we want to do is console.log moneybags or something payment success all right so we will log that out to the console if that is successful and that's where you might you know print a shipping label or send an email or you know start some order process on your end okay so we're gonna take out that console log and the next thing we need to talk about is this payload where does this payload come from now in practice if we were just gonna await that request.json we're going to get back a javascript object we're going to get back an object that has been parsed so the the payload body that came in as a string of data that looked like json was parsed into a json object but when we're confirming those signatures match we don't want a json object instead what we want is the raw payload we need that raw string payload so what we're going to do here is we're going to say that the payload is the raw text of the request so request.txt gives us back the raw text of the request that returns a promise that we can await and then we're going to say that payload is that value so here we're passing in that raw text value that is the the text of the request so let's just clear out our server log here for just a second now in order also in order for us to use stripe here successfully we need to import stripe from stripe that's the stripe node client library and we're going to say const stripe is new stripe process.n dot stripe secret key and we should be ready to test this out so let's go back to localhost 3000 and walk through our payment flow one more time and we're gonna keep an eye on these server logs so we're gonna buy a book that received a post request to the web hook endpoint and we got a 200. we're no longer logging out the entire payload of um of the event object but we can see that we did get a 200. the other thing you can check too is the server logs for the events that are firing on your account so down here we're seeing that payment intents are being created and those are all being passed as webhook post notifications to our endpoint here so now we can go through the flow enter in some payment details and click on pay and that should successfully end up in a payment intent that succeeded event which we can see here payment success is logged out to the console all right that's it this is a web hook handler for stripe web hooks in a remix application thank you so much for watching and we'll see in the next one --- [Back to all videos](https://www.cjav.dev/videos) --- ## Hey Agent, thanks for
