If a developer webhook endpoint keeps failing for a long stretch, the webhook portal disables it so Mando stops sending to a URL that is not working. This is a protection, not a penalty.
Why it happens
An endpoint is disabled after it fails to accept deliveries over and over: it is unreachable, times out, or keeps returning an error status instead of a success. A healthy endpoint should return a 2xx status quickly.
How to fix it
- Fix the endpoint so it accepts deliveries and returns a success status.
- Open Settings > Developer webhooks and re-enable the endpoint in the portal.
- Replay the deliveries it missed while it was disabled.
Frequently asked questions
Did I lose the events?
No. Re-enable the endpoint and replay the missed deliveries from the logs.
How do I avoid it?
Return a 2xx status quickly and keep your endpoint reachable. Do heavy work after acknowledging the delivery.
Does this affect Slack?
No. A failing Slack channel keeps trying and is not auto-disabled.
