Handling signed Stripe Webhooks with Edge Functions

Handling payments is a central part of building an online business. And when you're processing payments, for example with Stripe[0], you will need to create a webhook handler[1]. In this episode we'll look at handling signed Stripe Webhook events in Deno Edge Functions[2].

Again thanks for this Thor. One day i'll make again all of these steps you described to setup Stripe with Supabase because it is really useful!

This is the first time I try to do something like this. Thank you. I hate my life.

[KartickSadhu]

Thank you so much for this. It helps me a lot and save my time. Thank you again.

This is incredible work and it actually really helped me implement what I wanted but why does Thor keep smacking his mouth every few mins 🤣

I’m a bit confused cuz the webhook edge function gets all that info, but how do I set that info in my db? For example, I my function successfully triggers on a payment complete. I get that logged out fine, but now I want to put it in my db

Thanks for this video! What I don't understand here is the apikey – Supabase always requires the apikey header to be present (as far as I know), but presumably Stripe doesn't sent it when calling your endpoint. So how do you work around that?

[AbdelmadjidLablack]

I got this message " Please note: this key will expire after 90 days, at which point you'll need to re-authenticate. " What should I do and how should i do it after 90 days ?

I followed all the steps, but after triggering the Stripe event locally I get a 404 response from supabase.
