# Add a check to a playbook

`POST /playbooks/{id}/checks`

## Request

- Base URL: `https://app.gc.ai/api/external/v1`
- URL: `https://app.gc.ai/api/external/v1/playbooks/{id}/checks`
- Auth: API key in header `Authorization`
- TypeScript: <https://skmtc.dev/gc-ai/apis/gc-ai-external-api/docs/playbooks/:id/checks/post.ts> (a function with typed inputs; its response is checked against the schema)

## Request body

  - `positions` PlaybookCheckPositionInput[], required: The check's positions: exactly one `standard` position plus any number of `fallback` positions.
    - `type` 'standard' | 'fallback', required: Use `standard` for the primary stance and `fallback` for an alternative the reviewer may accept.
