Troubleshooting & FAQ

Status shows ✗ but webhooks still arrive.

• Cause: some endpoints reject the OPTIONS request (for example HTTP 405 Method Not Allowed), so the status check fails even though the endpoint does accept POST events.
• Fix: use Test instead of relying on the status check. Test POSTs a real payload, so it confirms the endpoint is receiving events.

A webhook moved to Failed.

• Cause: the endpoint failed or timed out repeatedly, so ServiceM8 deactivated the subscription automatically.
• Fix: fix the endpoint so it returns a 2xx response within 10 seconds, use Test to confirm it receives events, then select Reactivate.

"This event and callback URL is already registered."

• Cause: the same event plus callback URL is already registered as a webhook.
• Fix: edit the existing webhook instead, or use a different callback URL or event. The same callback URL with a different event is allowed.

Reactivate says the subscription is still not active.

• Cause: the endpoint is still failing or timing out, so ServiceM8 will not keep it active.
• Fix: fix the endpoint first, use Test to confirm it receives events, then try Reactivate again.

Delete is not offered for Failed or Deleted webhooks.

• Cause: Failed and Deleted webhooks are already inactive, so there is nothing to delete — the subscription is no longer live.
• Fix: use Reactivate instead if you want the webhook to start receiving events again.
