## Definitions

### `chat.yakka.getTimeline`

**Type**: `query`

A page of a channel's timeline, newest first, ordered by view sequence (ADR 0012). Paging is by sequence and never by timestamp or record key: TIDs order a repo, never a channel, and two authors' clocks are not comparable.

#### Parameters

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `limit` | `integer` | No |  |
| `before` | `integer` | No | Page backwards from this sequence, exclusive. Omit for the newest page. |
| `channel` | `string` | Yes | The channel's id. |

#### Output

**Encoding**: `application/json`

#### Errors

- **ChannelNotFound**
- **ChannelForbidden**: The credential mint declined (ADR 0007). The channel exists and this viewer may not read it — a different fact from it not existing, and reported as one.
