Webhooks

When a WhatsApp user taps on a reply button, a messages webhook is triggered that describes their selection in a button_reply object:

"button_reply": {
  "id": "<BUTTON_ID>",
  "title": "<BUTTON_LABEL_TEXT>"
}

<BUTTON_ID> — The button ID of the button tapped by the user.

<BUTTON_LABEL_TEXT> — The button label text of the button tapped by the user.
