| Category | string | The use of different category tags enables the business to send messages for different use cases. For Facebook Messenger they need to comply with their Messaging Types policy. Nexmo maps our `category` to their `messaging_type`. If `message_tag` is used, then an additional `tag` for that type is mandatory. By default Nexmo sends the `response` category to Facebook Messenger. | [optional] |
| Tag | string | ‘A full list of the possible tags is available on developers.facebook.com' | [optional] |
