Path Parameters
Name of the Sandbox
Id of the Schedule
Body
application/json
A scheduled task that executes a process inside the sandbox at specified times. Stored in the dedicated schedules table (no longer embedded in the sandbox spec).
Unique identifier for this schedule within its sandbox. Auto-generated if not provided.
Example:
"schedule-0"
Process execution configuration for a scheduled sandbox task
Show child attributes

Maximum number of execution records kept for this schedule. Once reached, recording a new execution deletes the oldest. Defaults to 100.
Example:
100
Type of schedule timing. 'cron' for recurring (5-field expression), 'at' for a specific RFC 3339 datetime, 'sleep' for a duration from now (resolved to 'at' on creation).
Available options:
cron, at, sleep Example:
"cron"
Timing value. For 'cron': a 5-field cron expression (e.g. '0 8 * * 1-5'). For 'at': an RFC 3339 datetime (e.g. '2026-07-01T09:00:00Z'). For 'sleep': a duration (e.g. '2h', '30m', '7d').
Example:
"0 8 * * 1-5"
