## Definitions

### `dev.knotless.putPreferences`

**Type**: `procedure`

Changes the asking account's preferences, as the appview keeps them: each one given takes the place of the one of its kind, and the rest stay. Answers them all, as dev.knotless.getPreferences does. Requires authentication: a service token, or the session cookie the pages' login sets, from the pages themselves.

#### Input

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `preferences` | `array` | Yes | The preferences to set, at most one of each kind. |

#### Output

**Encoding**: `application/json`

#### Errors

- **InvalidRequest**: A kind of preference the appview does not keep, or one not as its kind says: a theme not named as the pages name theirs, or a reason the appview does not give.
- **AuthenticationRequired**: No account asks.
- **NotFound**: This appview keeps no index, so it keeps no preferences.
