Why am I getting Unsupported Type Messages API callbacks?


What does the Unsupported Type callback do?

Applies To

  • Messages API
  • Unsupported Type Callback


Unsupported Type callbacks were made available in September 2020. When a social channel (WhatsApp, Viber, Facebook Messenger) releases a feature that Vonage has not yet implemented, ee send on a callback letting our customers know that this type of message is unsupported. The Unsupported type callback helps improve the overall developer experience.

For example, if a customer is using a chatbot or AI, they may want to be able to recognize an Unsupported type message in the callback, so that they may then respond with something like, “I’m sorry I can’t see that last message. Can you send as text?”

If any new inbound message types are released across our supported message channels, they will immediately be flagged as unsupported so no additional development work will be required to add them.
