500

Quick Fix

Check the webhook URL and verify the signing secret. Ensure your endpoint returns a 200 status. If the error persists, review server logs and increase timeout settings.

What it Means

When Stripe sends an event to your webhook, it expects a 2xx response. A 500 Internal Server Error means your server returned an internal error, causing Stripe to retry the event. This indicates a problem in your webhook handler such as missing secret verification, code exceptions, or resource limits.

Possible Causes

• 1
  Incorrect webhook signing secret
• 2
  Endpoint returns non‑2xx status
• 3
  Server timeout or crash
• 4
  Missing required headers
• 5
  Code exception in handler

Step-by-Step Solutions

1. Verify Signing Secret

   Retrieve the secret from the Stripe dashboard and compare it to the value your code uses. A mismatch causes verification failures and 500 errors.

   echo $STRIPE_WEBHOOK_SECRET
2. Inspect Endpoint Code

   Look for unhandled exceptions, missing imports, or logic that might crash. Wrap processing in try/catch and log errors.

   sed -n '1,200p' webhook_handler.py
3. Test with Stripe CLI

   Use the CLI to trigger events and see real‑time responses. This helps isolate the issue.

   stripe trigger payment_intent.succeeded
4. Check Server Logs

   Review logs for stack traces or resource errors that caused the 500 response.

   tail -f /var/log/webhook.log
5. Adjust Timeout Settings

   Increase the timeout if your handler takes longer than the default. This prevents premature termination.

   export TIMEOUT=60
6. Confirm 200 Response

   After processing, explicitly return a 200 OK to acknowledge receipt to Stripe.

   return Response(status=200)
