I guess this can help:

> **[Messages | Chat Platform API | Sendbird Docs](https://sendbird.com/docs/chat/v3/platform-api/guides/messages#2-send-a-message)**
>
> Learn about the three types of messages: text, file or admin messages.

When you send a message you can specify **message\_type**

Something like:

```auto
POST /v3/group_channels/test-channel/messages

```

Body:

```auto
{
    "message_type": "ADMM",
    "message": "message from Admin"
}

```

Don’t forget you Api-Token in your headers.

The only parameter I can help pointing out is: **created\_at**

Specifies the time that the message was sent, in [Unix milliseconds](https://sendbird.com/docs/chat/v3/platform-api/guides/miscellaneous#2-timestamps) format. This property can be used when migrating the messages of other system to Sendbird server. If specified, the server sets the time of message creation as the property value.

```auto
const d = new Date('2020-11-30');
var millisecs = d.getTime(); // This will result in something like: 1606694400000

```

You body would be:

```auto
{
    "message_type": "ADMM",
    "message": "message from Admin on 2020-11-30",
    "created_at": 1606694400000
}

```

In your message list you will see this message listed according to this date.

Then, **custom\_type** is a field you can populate with any value you need. The length is limited to 128 characters.
