# updateScheduledTask

Change a scheduled task; only what you send changes. `timing` is { cronExpression or fireAt, timezone }, exactly one of the two. `clearExpiresAt: true` removes its end (do not send it with `expiresAt`). Only the task's owner or an org admin may change it (`canEdit`).

- Call: `POST https://server.goliathdata.com/api/v1/call` with `{ "operationId": "updateScheduledTask", "variables": {...} }`
- Scope: `WRITE`
- Type: mutation
- Idempotency: honors `Idempotency-Key` (24 h)
- Rate-limited: no
