# PATCH /experimental/schedules/{id}

`PATCH /experimental/schedules/{id}`

Pauses/resumes a schedule (`status`) and/or updates its `cron`, `timezone`, or `label`. Cron and timezone changes apply to the next scheduled occurrence; status and label changes apply immediately.

## Path parameters

- `id` string, uuid, required

## Headers

- `Authorization` string

## Request body

- object
  - `status` union
    - 'active'
    - 'paused'
  - `cron` string — New cron expression the schedule fires on, interpreted in `timezone`. Rejected if unparseable or if its tightest interval is under the minimum allowed.
  - `timezone` string — New IANA timezone the cron is interpreted in. When supplied without `cron`, re-interprets the existing cron in the new zone.
  - `label` string
  - `description` string
  - `timeoutMs` integer, nullable — Per-run override, in milliseconds, for how long each fired run may work before it is timed out. Extends the default 50-minute timeout (3000000) up to 6 hours (21600000). Must be a whole number of minutes (a multiple of 60000). Omitted keeps the default.
