## Definitions

### `chat.sprk.convo.removeReaction`

**Type**: `procedure`

Removes an emoji reaction from a message. Requires authentication. It is idempotent, so multiple calls from the same user with the same emoji result in that reaction not being present, even if it already wasn't.

#### Input

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `value` | `string` | Yes |  |
| `convoId` | `string` | Yes |  |
| `messageId` | `string` | Yes |  |

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `message` | `ref` → `chat.sprk.convo.defs#messageView` | Yes |  |

#### Errors

- **ReactionMessageDeleted**: Indicates that the message has been deleted and reactions can no longer be added/removed.
- **ReactionInvalidValue**: Indicates the value for the reaction is not acceptable. In general, this means it is not an emoji.
