GoHighLevel Webhooks Not Working: How to Troubleshoot Failed Data Transfers
When a GoHighLevel webhook fails to send data, the problem can be inside GoHighLevel or at the receiving endpoint. Before changing the workflow, find out whether the webhook is firing and what the receiving application is returning. The response usually tells you which side has the problem.

Find which side is failing
A webhook has two halves. GoHighLevel sends the request, and the receiving application accepts and processes it. A failure can be on either side. If GoHighLevel never sent the request, the problem is in the workflow. If GoHighLevel sent it but the receiver rejected it, the problem is at the endpoint. The first step is to find out which one is failing.
What to check first
- Confirm the workflow reached the webhook step in the history.
- Check whether the webhook request was actually sent.
- Look at the HTTP response the receiving endpoint returned.
- Compare the payload being sent to what the receiver expects.
- Confirm the webhook URL is correct and still active.
The workflow never reached the step
If the workflow history shows the contact stopped before the webhook step, the webhook never fired. The problem is earlier in the workflow, not in the webhook itself. Find where the contact stopped and fix that before investigating the webhook. A webhook that never sends is a workflow problem, not an integration problem.
The request was sent but rejected
If the webhook fired but the data did not arrive, the receiving endpoint may have rejected the request. The HTTP response tells you what happened. A success response means the receiver got it. An error response means the receiver refused it, usually because of missing authentication, a wrong payload format or a missing field. Read the response to find the cause.
Field mapping and missing values
The receiving application expects certain fields in a certain format. If the payload is missing a required field, or a field is in the wrong format, the receiver may reject the request. Compare the payload GoHighLevel sends to the documentation for the receiving endpoint. A single missing required field can cause the whole transfer to fail.
Authentication problems
If the receiving endpoint requires authentication, a missing or expired token will cause every request to fail. Confirm the authentication method the endpoint expects and that the credentials in the webhook configuration are correct and current. A token that worked when the workflow was built may have expired since.
How to diagnose a webhook
- 1.Check the workflow history to confirm the webhook step ran.
- 2.Look at the HTTP response code the endpoint returned.
- 3.If the request was not sent, fix the earlier workflow step.
- 4.If the request was rejected, compare the payload to the endpoint docs.
- 5.Confirm authentication is correct and the URL is still valid.
Frequently Asked Questions
Why is my GoHighLevel webhook not working?
The workflow may not have reached the webhook step, the receiving endpoint may have rejected the request, the payload may be missing a required field or the authentication may be wrong. Check the workflow history and the HTTP response to find which side is failing.
How do I know if a GoHighLevel webhook failed inside GHL or at the endpoint?
If the workflow history shows the contact stopped before the webhook step, the problem is in the workflow. If the step ran, look at the HTTP response the endpoint returned. A success response means the receiver got it, an error response means the receiver refused it.
