## Definitions

### `chat.yakka.toggleReaction`

**Type**: `procedure`

Add or remove the viewer's reaction to a message. A reaction is a record in the viewer's own repo, so this creates or deletes one — there is no shared counter to increment, and the count a client renders is the appview's tally of records it has ingested.

#### Input

**Encoding**: `application/json`

#### Output

**Encoding**: `application/json`

#### Errors

- **MessageNotFound**
- **ChannelForbidden**

### `chat.yakka.toggleReaction#input`

**Type**: `object`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `uri` | `string` (at-uri) | Yes |  |
| `emoji` | `string` | Yes |  |

### `chat.yakka.toggleReaction#output`

**Type**: `object`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `mine` | `boolean` | Yes | Whether the viewer now reacts with this emoji — the state after the toggle, so a client need not guess which way it went. |
