# Update a trigger

> Source: https://docs.clonepartner.com/api-reference/triggers/update-trigger/

`PUT /api/triggers/{id}`

Partial update. one_off datetime rules are validated against the trigger's effective type (the stored type when `type` is omitted). Changing a one_off trigger's cron_expression resets last_triggered_at so the new datetime fires even after a server restart.

**Operation ID:** `updateTrigger`

## Authentication
