​
Handling Button Responses

When a user taps a button, you receive a webhook: 
{
  "event": "message.received",
  "data": {
    "from": "+14155551234",
    "type": "button_reply",
    "button": {
      "id": "good",
      "title": "Good"
    }
  }
}
Use meaningful IDs like confirm_order or cancel_order to make webhook handling easier.
