Zapier webhook trigger not firing

If a Zapier webhook trigger isn’t firing, it usually comes down to one of a few things:

Quick checks

1. Make sure the Zap is turned on

   • In Zapier, the Zap must be enabled for the trigger to listen.

2. Confirm you’re using the correct webhook URL

   • For Catch Hook triggers, verify the exact URL in Zapier.
   • Any typo, old URL, or staging/prod mix-up will prevent hits.

3. Check that the request is actually being sent

   • Use your app logs, browser dev tools, or Postman/cURL to confirm the webhook call is happening.
   • A webhook that never leaves the source system can’t trigger Zapier.

4. Verify the request method and content

   • Zapier webhooks generally expect a valid HTTP request.
   • Commonly this is a POST request with the right body format.

5. Look at the Zapier task history

   • If Zapier received the webhook but the Zap didn’t continue, task history may show the issue.
   • If there’s nothing there, Zapier likely never received the request.

6. Check for filters or paths in the Zap

   • A filter step may be stopping the Zap after the trigger fires.
   • Paths can also route the event away from the expected action.

7. Test with a known-good request

   • Send a simple test payload directly to the webhook URL using cURL or Postman.
   • Example:

     curl -X POST 'YOUR_ZAPIER_WEBHOOK_URL' \
       -H 'Content-Type: application/json' \
       -d '{"test":"hello"}'
     

8. Make sure the payload is valid

   • Invalid JSON, malformed headers, or empty bodies can cause issues depending on your setup.

9. Check for rate limits or authentication requirements

   • If the source app requires auth/signatures, make sure those are correct.
   • Some services retry or fail silently if auth is wrong.

10. Wait a minute and refresh

• Sometimes Zapier is a little delayed in test mode or while polling/processing.

If this is a “Catch Hook” trigger

• Go to the trigger step and click Test trigger
• Make sure Zapier is actively waiting for a sample
• Then send the webhook again

If this is a “Retrieve Polling” trigger

• It’s not a real webhook listener
• Polling triggers check on a schedule, so they won’t fire instantly

If you want, I can help you troubleshoot it step by step. Paste:

• the Zapier trigger type
• the webhook source
• a sample payload
• whether this is test or live mode
