Media
Upload a file once (multipart / form-data, field name `file`, up to 16 MB) and get back a hosted public URL you can reuse across sends — for example a PDF to use as a document-header on a template, or an image on a message.

Enroll a contact into an automation flow (chatbot) and manage your flows through the API.
Message
Send a single message on ANY connected channel — WhatsApp (default), Facebook Messenger, Instagram or Telegram — by setting `channel` and `to` (phone / PSID / IGSID / chat_id). Text, media (image / video / document / audio) or a location pin; a file can be attached directly as a multipart `media` field or referenced by a public URL. Then read a message's delivery status or your history. Note: Facebook, Instagram and Telegram only accept a business-initiated message inside the platform's reply window (the customer must have messaged you first).
