What is the iMessage API?
The iMessage API is a REST interface for sending and receiving iMessages programmatically. Apple does not expose a public iMessage API — Blooio provides a fully-featured alternative with a dedicated iMessage-enabled phone number, webhooks for real-time events, and delivery tracking, all behind a simple HTTPS endpoint.
iMessage REST API
Standard HTTP verbs over JSON. Authenticate with a Bearer API key and start sending to any phone number or email in seconds.
Apple iMessage API
Apple does not publish an official iMessage API. Blooio runs real Apple infrastructure so your messages are delivered as blue bubbles, not SMS green bubbles.
Send iMessage from the API
One POSTrequest sends an iMessage with text, attachments, reactions, or a multipart bubble — no SDK install required.
iMessage business API
Unlike Apple Messages for Business (MSP enrollment required), Blooio lets any business start sending iMessages in minutes with a standard REST API.
