# Remove the assignment from a single workflow

`PATCH /monitoring-workflows/{id}/unassign`

Removes the current assignee from the monitoring workflow identified by `id`. Use this endpoint for single-workflow unassignment; use `PATCH /monitoring-workflows/unassign` for bulk unassignment. The workflow must not currently be in `REVIEWED_BY_CERTIFYOS` status — if it is, this endpoint returns HTTP 400 with `{"error": "..."}` rather than the unassignment result. Requires `MONITORING_WORKFLOW_ASSIGN` or `MONITORING_WORKFLOW_ASSIGN_SELF`. The `tenant-id` header is mandatory.

## Path parameters

- `id` string, required

## Headers

- `tenant-id` string, required

## Response `200`

Workflow unassigned: `{workflowId, error: null}`.

- UnassignmentResult — Result of an individual unassignment operation
  - `workflowId` string — ID of the monitoring workflow
  - `error` string — Error message if unassignment failed

## Other responses

- `400` — Bad request - Workflow is not in an unassignable state
- `401` — Unauthorized - Authentication required
- `403` — Forbidden - User does not have required permissions
- `404` — Monitoring workflow not found
- `500` — Internal Server Error - An unexpected error occurred
