Automation Webhook Not Firing: A Practical Troubleshooting Guide
When an automation webhook is not firing, the workflow reached the webhook action but no request was created. The cause is in the trigger, the webhook action configuration or the conditions that skip it. Determine whether the request is actually created before debugging the endpoint.

The webhook firing flow you are debugging
A webhook action sends an HTTP request when the workflow reaches it. The trigger fires, the workflow runs, the webhook action is reached, the request is created and the request is sent. If the webhook is not firing, one of those steps failed. The key question is whether the request was created at all. If it was never created, the problem is in the workflow. If it was created but not received, the problem is downstream.
| Step | What happens | Where it can break |
|---|---|---|
| 1. Trigger | Workflow starts | Trigger not configured or did not fire |
| 2. Workflow runs | Steps execute up to webhook | Condition skips the webhook action |
| 3. Webhook action reached | Action is evaluated | Action disabled or misconfigured |
| 4. Request created | HTTP request built | URL missing or invalid |
| 5. Request sent | Request leaves the platform | Network or endpoint issue |
What to check first
- Check the workflow history and confirm the webhook action was reached.
- If it was not reached, check the trigger and conditions.
- If it was reached, confirm the webhook URL is configured and valid.
- Check the request method and payload configuration.
- Check whether the action shows an error or a sent status.
Was the action reached
The webhook only fires if the contact reaches the webhook action step. If a condition routed the contact away or the workflow stopped earlier, the action never runs. Check the workflow history for the triggering contact and confirm the webhook action step was reached. This is the same workflow tracing covered in the guide on automation workflow stops halfway. An action that was never reached is a workflow problem, not a webhook problem.
Webhook action configuration
If the action was reached, check its configuration. The webhook URL has to be present and valid. A missing or malformed URL means no request is created. The request method, such as POST or GET, has to match what the endpoint expects. The payload has to be configured, whether it is a fixed payload, a dynamic mapping or the default event data. Confirm the URL, method and payload are all set correctly.
Conditions on the webhook action
Conditions can skip the webhook action. A condition that only sends the webhook for certain contacts or certain values may skip the action for the contact you are testing. Check the conditions on the webhook action step. This is the same condition diagnosis covered in the guide on automation conditions not working.
Production validation
A webhook that works in testing but not in production can have a different URL, different authentication or a different payload in each environment. Confirm the production workflow uses the production endpoint, not the test endpoint. This is covered in detail in the guide on webhook works in testing but not in production. If the request was created but the endpoint received nothing, the problem is in delivery, covered in the guide on webhook fires but no data arrives.
How to test it
- 1.Trigger the workflow for a test contact.
- 2.Check the workflow history and confirm the webhook action was reached.
- 3.If not reached, trace the trigger and conditions.
- 4.If reached, confirm the webhook URL, method and payload.
- 5.Check the action status for an error or sent confirmation.
- 6.Confirm the endpoint received the request.
Frequently Asked Questions
Why is my automation webhook not firing?
The webhook action may not have been reached because of a trigger or condition problem, or the action may be misconfigured with a missing or invalid URL. Check the workflow history to confirm the action ran, then verify the URL and payload.
How do I know if my webhook request was created?
Check the workflow history for the triggering contact. If the webhook action shows as run or sent, the request was created. If it shows as skipped or does not appear, the action was never reached.
