Retrieve a task

GET /api/v1/tasks/{id}

operationIdgetTask

Required level
Read only
Rate limit
read, 3,600 calls per hour

Status of a task: checking it is how you know an operation has completed. finished_at remains null while the task is running.

The identifier is opaque: do not try to build it or increment it. An unknown task and a task outside the key's scope return the same 404.

Polling every few seconds is enough: polling more often uses up the read rate limit without speeding anything up.

Path parameters

id string required

Identifier of the task, as returned when it was created or by GET /tasks.

Example: tsk_000002e1
