Send messages

Send one or more SMS or MMS messages in a single request. Each message is validated on its own: valid messages are sent, and any that fail are returned in data.errors with an error_code and a human-readable error_help that you should log.

Requests must be sent as application/json. To send an MMS, include a single image URL in media and send from an MMS-enabled dedicated number.
