# Set instance runtime configuration

`PUT /api/v1/config/custom`

Changing `instance.customizations.javascript` or `instance.customizations.css` requires a [password confirmation](#section/Password-confirmation): set `currentPassword` at the root of the request body.


Authentication (security requirement alternatives):

```json
[
  {
    "OAuth2": [
      "admin"
    ]
  }
]
```

- OAuth2: oauth2. Authenticating via OAuth requires the following steps:
- Have an activated account
- [Generate] an access token for that account at `/api/v1/users/token`.
- Make requests with the *Authorization: Bearer <token\>* header
- Profit, depending on the role assigned to the account

Note that the __access token is valid for 1 day__ and is given
along with a __refresh token valid for 2 weeks__.

Responses:

- 200: successful operation

- 400: Arises when:
  - the emailer is disabled and the instance is open to registrations
  - web videos and hls are disabled with transcoding enabled - you need at least one enabled
  - the custom JavaScript or CSS changed and `currentPassword` is missing


- 403: invalid `currentPassword`, or password confirmation unavailable for this user

- 429: too many failed password confirmations
