POST /v1/chats and later ones with POST /v1/chats/{chat_id}/messages. Messages from the people you text reach you through webhooks.
A message is a list of parts, sent in order: text, a photo or file, a link, a voice memo or a contact card. Blujay picks iMessage, RCS or SMS for each person unless you choose one.
