# Instagram channel properties

There are Instagram channel-specific properties that can be used when making calls to the Conversation API. These properties can be listed under `channel_properties` in the message request.

For example, below is the code for adding the channel specific property `INSTAGRAM_MESSAGE_TAG` to a Conversation API call:


```json
{
  "app_id": "{{APP_ID}}",
  "recipient": {
    "identified_by": {
      "channel_identities": [
        {
          "channel": "INSTAGRAM",
          "identity": "{{INSTAGRAM_IDENTITY}}"
        }
      ]
    }
  },
  "message": {
    "text_message": {
      "text": "Text message from Sinch Conversation API."
    }
  },
  "channel_priority_order": ["INSTAGRAM"],
  "channel_properties": {
    "INSTAGRAM_MESSAGE_TAG": "HUMAN_AGENT"
  }
}
```

The relevant Instagram channel properties are detailed in the table below:

| Property name | Property value |
|  --- | --- |
| `INSTAGRAM_MESSAGE_TAG` | Required on the Instagram channel when providing human agent support. All messages sent by a human agent outside of a normal 24-hour response window must use the `HUMAN_AGENT` tag. The `HUMAN_AGENT` tag allows messages to be sent within 7 days after the end-user’s last message. |
