title: 1008: Event kind unknown. | API Docs
description: An event kind in event_kinds is not one this API emits.
---

**HTTP status:** `422`. May also be reported as a field-level finding in `error.details[]`.

The webhook endpoint request names an event kind this API does not emit. Only documented kinds can be subscribed to.

## Troubleshooting

- Inspect details\[].param for the offending index in event\_kinds and compare it with the event kinds listed on the webhook endpoint operation.
