This object represents a unique message identifier.

| Field | Type | Description |
| --- | --- | --- |
| message\_id | Integer | Unique message identifier. In specific instances (e.g., message containing a video sent to a big chat), the server might automatically schedule a message instead of sending it immediately. In such cases, this field will be 0 and the relevant message will be unusable until it is actually sent. |
