How to send Audio/video file as response back facebook chatbot
We have a requirement, where an audio file has to be sent to facebook chatbot user as a response to a command.As of now in facebook channel configuration, we can select response type as Text,Menu,Custom,cancel,restart,authenticate , but there is no response type as file or something.
It would be helpful to know any approach on how to achieve it
