Hi, it appears that you're getting a time_out error. We talk about how you need to pass 200 immediately: https://docs.stripe.com/webhooks#webhook-endpoint-def

The response header is something your code would pass to us.

#

Please follow this guide: https://docs.stripe.com/webhooks/quickstart

I mean request headers

#

context.log("🔹 Request Headers:", JSON.stringify(request.headers, null, 2));

#

comes empty

Hello!

rain vault Feb 21, 2025, 4:49 PM

context.log("🔹 Request Headers:", JSON.stringify(request.headers, null, 2));

#

request.headers comes to the webhook empty

#

Hence error here - const sig = request.headers['stripe-signature'];

What platform are you running your webhook endpoint on?

rain vault Feb 21, 2025, 4:50 PM

Azure functions

hello, Am using Azure function (Serverless function)

hello

#

Ok cool, I gotcha. I'm not familiar with that one. Have you tried looking at the contents of the whole request object to see what's there?

rain vault Feb 21, 2025, 4:56 PM

#

here is the request

Request: HttpRequest {
query: URLSearchParams {},
params: {
id: 'evt_3QuyzY2BmsN6YOna0XndJChz',

I did context.log("🔹 Request:", request);

Are you testing in live mode?

rain vault Feb 21, 2025, 5:00 PM

No, it wasn't working in live mode thats why I decided to debug and test in TEST MODE

Ahh ok gotcha.

const headers = Object.fromEntries(request.headers.entries());

#

Are you parsing them in that particular way? Also apparently Azure is silly. ¯_(ツ)_/¯

#

You're also going to need to access the raw request body or you won't be able to verify the signature.

rain vault Feb 21, 2025, 5:05 PM

#

Naaa, am not passing them in any partiular way. Do I need to access the raw body in a particular way?

#

I guess this will work

const headers = Object.fromEntries(request.headers.entries());

proven horizon Feb 21, 2025, 5:07 PM

#

It looks like you might do that like this with Azure (using .text()) https://stackoverflow.com/a/78559789/379538

If you can get the signature and the raw body to use with it, you'll be good to go; if not, you'll have to raech out to Azure to find out more.

Am trying to access stripe-signature

What does headers contain after you do that?

I don't get your question

JSON.stringify(headers, null ,3) looks like what when you log it?

Cool, so you've got the signature now.

rain vault Feb 21, 2025, 5:22 PM

#

Yeah fabulous

proven horizon Feb 21, 2025, 5:23 PM

#

Now make sure you're using the raw body to compare it with, and you should be good to go.

rain vault Feb 21, 2025, 5:25 PM

#

I guess this help to get the raw body

const rawBody = await request.text();
const bodyBuffer = Buffer.from(rawBody, 'utf8');

proven horizon Feb 21, 2025, 5:26 PM

#

Try just using the contents of request.text() first. Otherwise you could use request.buffer().

rain vault Feb 21, 2025, 5:27 PM

ok

Is it possible to Trunate Event before logging?

Is an azure issue pls

proven horizon Feb 21, 2025, 5:59 PM

#

Everything beyond what we've done already is an Azure issue, ya - once Azure can give you the right body content, you can verify it. I unfortunately don't know ~anything about Azure Functions other than what I could google so I've hit the limit of how much I can help here.
