You can use platform_metadata attribute to send tracking data directly to Viber API. This allows you to track messages and user’s replies. Tracking data are received back as metadata.platform_metadata attribute with message replies from the user.

{
  "channel": { ... },
  "contact": { ... },
  "content": { ... },
  "metadata": {
    "platform_metadata": "these data are going to be sent directly to Viber API as tracking_data attribute"
  }
