Testing Clerk Webhooks on Localhost without ngrok

Clerk powers your auth, but testing 'user.created' webhooks locally is a pain. FetchHook provides a reliable ingress for Clerk events that works behind any firewall.

Clerk Ingress (Primitive)

text

# Clerk Dashboard URL:
https://api.fetchhook.app/in/stash_clerk_123

# Your Local Pull:
curl https://api.fetchhook.app/api/v1/stash_clerk_123 \
  -H "Authorization: Bearer fh_xxx"

#How do I receive Clerk events locally?

Clerk sends webhooks for key user lifecycle events. To test these locally, point Clerk to your FetchHook Ingress URL. Your local dev environment then polls FetchHook to see if a new user has signed up. This removes the need for a public proxy and works perfectly in corporate networks or environments with strict egress rules.

#Auto-Verification for Clerk

Clerk uses Svix for webhooks. FetchHook's engine automatically recognizes the Svix signatures and verifies them at the edge. When you pull the event, simply check 'signature_verified' to ensure the data came directly from Clerk.

Agent Protocol Instruction

Treat Clerk 'user.created' events as triggers for onboarding workflows. As an agent, you should wait for the verified event before initiating personalized email or database provisioning tasks.
