# Resume Operation

`POST /v1/operations/{operation_id}/resume`

## Request

- Base URL: `https://api.robosystems.ai` (the document declares no server; this is the origin it was published from)

- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

Answers an operation that paused at a checkpoint (status `awaiting_input`) and puts it back on the worker queue with the answer. The operation keeps its id, so the stream, status and cancel links stay valid; reconnect to `/stream` to follow the resumed run. Consumes no credits.

## Path parameters

- `operation_id` string, required: Operation identifier

## Request body

- OperationResumeRequest: Answer for an operation paused at a checkpoint (`awaiting_input`).
  - `input` object: The decision the paused run asked for, in whatever shape its prompt described. Delivered to the task as `params['resume']['input']`.
