# Telegram Bot channel properties

There are Telegram Bot 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 `TELEGRAM_DISABLE_LINK_PREVIEW` to a Conversation API call:


```json
{
  "app_id": "{{APP_ID}}",
  "recipient": {
    "contact_id": "{{CONTACT_ID}}"
  },
  "message": {
    "text_message": {
      "text": "Text message from Sinch Conversation API."
    }
  },
  "channel_priority_order": ["TELEGRAM"],
  "channel_properties": {
    "TELEGRAM_DISABLE_LINK_PREVIEW": "TRUE"
  }
}
```

The relevant Telegram Bot channel properties are detailed in the table below:

| Property name | Property value |
|  --- | --- |
| `TELEGRAM_DISABLE_LINK_PREVIEW` | When message content contains a URL, by default Telegram will analyze the URL and get a preview for it. Use this parameter to disable link preview. |
