# Update Key Date

`PUT /thirdparties/key-dates/{key_date_id}`

## Request

- URL: `https://api.kobaltlabs.com/thirdparties/key-dates/{key_date_id}`
- Auth: none declared

## Path parameters

- `key_date_id` string, uuid, required

## Request body

- UpdateKeyDateRequest
  - `label` string, nullable
  - `month` integer, nullable
  - `day` integer, nullable
  - `first_year` integer, nullable
  - `interval_years` integer, nullable
  - `active` boolean, nullable

## Response `200`

Successful Response

- KeyDateMutationResponse
  - `key_date_id` string, uuid, required
  - `status` 'proposed' | 'active' | 'superseded', required: Lifecycle of a key date. Distinct from the ``AnnualKeyDates.active`` boolean, which only toggles notifications on an already-real key date. An ``ACTIVE``-status key date may still have ``active=False`` notifications.
  - `message` string

## Other responses

- `422`: Validation Error
