Create Schedule - BlobHub

Create a new schedule in the scheduler blob revision. The schedule is registered with the underlying scheduling service immediately and begins firing according to its configuration once it becomes active.

POST `/revisions/:id/data/command` (Command: `create_schedule`)

Request Body

Parameter	Type	Required	Description
`engine`	string	Yes	Must be `scheduler_blobhub`.
`command`	string	Yes	Must be `create_schedule`.
`alias`	string	No	Optional stable name for the schedule. 6–42 chars, lowercase (`a`–`z`, `0`–`9`, `_`, `-`), unique in the revision.
`repeat`	string	Yes	Either `one_time` or `recurring_cron`.
`timezone`	string	Yes	IANA timezone name (e.g. `America/New_York`, `UTC`).
`invocation_target_type`	string	Yes	Must be `workflow`.
`invocation_target`	object	Yes	Target to invoke when the schedule fires. See Overview for field details.
`cron_expression`	string	Conditional	Required when `repeat` is `recurring_cron`. Six-field AWS cron expression.
`invocation_time`	string	Conditional	Required when `repeat` is `one_time`. ISO 8601 datetime without timezone suffix (e.g. `2026-05-01T14:30:00`), interpreted in the schedule’s `timezone`.
`enabled`	boolean	No	Whether the schedule is initially enabled. Defaults to `true`.
`start_date`	string	No	ISO 8601 UTC datetime before which the schedule does not fire.
`end_date`	string	No	ISO 8601 UTC datetime after which the schedule does not fire.

The schedule’s own alias names the schedule itself. It is unrelated to invocation_target.workflow_alias, which names the separate workflow definition the schedule invokes when it fires — the two keys sit side by side below but identify different objects.

Response

Parameter	Type	Description
`schedule`	object	The created schedule object.

The schedule records the user_id of the user who created it. Scheduled executions this schedule triggers run as that user — which is what lets those executions, and any writes they make, be attributed back to a real identity.

Errors

Status	Error	Cause
400	`alias_in_use`	The alias is already taken in this revision.
