Receiving webhooks with Supabase Edge Functions

Receiving Webhooks is a crucial aspect of integrating with third-party services, allowing developers to automate their workflows and stay up-to-date with changes in real-time. Webhooks are essentially POST requests to a preset endpoint, used by services to notify each other of events. To receive webhooks successfully, it's essential to implement proper security measures, such as verifying the origin of the message through signature validation. In this tutorial, we'll set up a Supabase Edge Function to receive a webhook from Svix and validate the webhook signature. We'll cover the basics of webhook verification, including calculating the expected signature using HMAC with SHA-256, and implementing a try/catch block to handle returning the correct response based on whether the signature matches our expected signature.
