# Update promotion

`PATCH /api/v1/promotions/{id}`

Partially updates a promotion by its identifier. The code is immutable. Editing content is blocked while the promotion is active and in effect; toggling "active" is always allowed.

## Path parameters

- `id` string, uuid, required

## Request body

- PromotionUpdate

## Response `200`

Promotion updated.

- PromotionUpdateResponse
  - `metadata` object, nullable, required

## Other responses

- `400` — Request payload, query string, or path parameter failed validation.
- `401` — Authentication is missing, malformed, expired, or refers to a session that is no longer active.
- `403` — The caller is authenticated but lacks the required permission for this action.
- `404` — Promotion not found in the caller account.
- `422` — The payload passed schema validation but breaks a domain invariant, references a missing entity, or the promotion cannot have its content edited in its current lifecycle state.
- `500` — Unexpected server error. The response body never leaks internal details.
