Message Request

Send messages through the Unifier API, including fallback routes to alternate channels if the primary delivery attempt fails.

POST /v1/messages accepts a sender, receiver, and channel (rbm, sms, telegram, whatsApp, email, instagram, or facebook) along with a message body, which can be plain text, a file, audio, picture, video, location, contact card, email, WhatsApp template, or a richer RBM card, carousel, or suggestions payload. An optional fallback array lets you queue one or more alternate messages - potentially on different channels - that are sent automatically if the primary message is not delivered.
