# Update Project API Key

`PUT /v1/projects/{projectId}/api-keys/{apiKeyId}`

## Path parameters

- `projectId` string, required
- `apiKeyId` integer, required

## Request body

- UpdateApiKey
  - `valid` boolean, required — Set to `false` to deactivate the key, or `true` to reactivate it

## Response `200`

- ApiKeyResponse
  - `success` boolean, required — Indicates if the request was successful
  - `data` object, required
    - `apiKey` ApiKey
      - `id` integer, required — Unique identifier for the API key
      - `name` string, nullable — Human-readable label for the API key
      - `valid` boolean, required — Whether the key is active. A deactivated key is rejected on authentication.
      - `value` string, required — The API key value. This is redacted (only the last 6 characters are shown, prefixed with asterisks) on every response **except** the create response, where the full value is returned exactly once.
      - `created_at` string, date-time, required — ISO 8601 timestamp of when the key was created
