Send, receive, verify, and automate iMessage conversations through one API — with webhooks, delivery events, SDKs, and fallback routing.
Why Blooio API exists
Why Blooio API exists
The Blooio API is a REST interface for communicating across any channel programmatically — complete with fully-featured dedicated iMessage-enabled phone numbers, 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
Blooio runs real Apple infrastructure so your messages are delivered as blue bubbles, not SMS green bubbles.
Send iMessage from the API
One POST request sends an iMessage with text, attachments, reactions, or a multipart bubble — no SDK install required.
iMessage business API
Unlike Apple Messages for Business, Blooio lets any business start sending iMessages in minutes with a standard REST API.

Frequently Asked Questions
Questions? Check the docs or reach out anytime.
What is the iMessage API?
The iMessage API is a REST interface for sending and receiving iMessages programmatically. Apple does not offer a public iMessage API. Blooio provides a fully-featured REST API with a dedicated iMessage-enabled phone number, webhooks for real-time events, and delivery tracking — all behind a simple HTTPS endpoint.
Does iMessage have an API?
Apple does not offer a public iMessage API. However, Blooio provides a fully-featured REST API that lets you send and receive iMessages programmatically. You get webhooks for real-time events, delivery tracking, read receipts, and support for attachments.
Is there an official Apple iMessage API?
No. Apple does not publish an official iMessage API, and Apple Messages for Business is invite-only, inbound-only, and closed to new MSP partners in 2026. Blooio fills that gap with a REST API on real Apple infrastructure — a dedicated iMessage-enabled number, outbound and inbound messaging, webhooks, and SDKs — so you can integrate Apple iMessage without an Apple developer program approval.
How do I send iMessages programmatically?
With Blooio's API, you make a simple POST request to send an iMessage. Pass the recipient's phone number and your message text, and Blooio handles delivery through real Apple infrastructure.
What is the iMessage API pricing?
Blooio starts at $39/month for a dedicated iMessage-enabled number with unlimited messages. There are no per-message fees, no segment charges, and no hidden costs. A free trial is available with no credit card required.
Can I use iMessage for business messaging?
Yes. Blooio is purpose-built for business iMessage communication. Use it for sales outreach, appointment reminders, customer support, and AI agent workflows.
What happens if the recipient doesn't have iMessage?
Blooio automatically checks each contact's capabilities before sending. If iMessage isn't available, you can fall back to RCS (for Android) or SMS via integrated Twilio support — all through the same API endpoint.
Does the iMessage API support webhooks?
Yes. Blooio provides real-time webhooks for message delivery, read receipts, reactions, and incoming messages. You can filter events by type, rotate signing secrets, and replay failed deliveries.
Does Blooio provide an iMessage SDK for Node.js, Python, Go, or Java?
Yes. Blooio maintains official open-source SDKs for Node.js / TypeScript, Python, Go, and Java. Each SDK wraps the REST API with typed clients, automatic retries, and webhook helpers. Install via npm, pip, Go modules, or Maven/Gradle.
Is Twilio's iMessage API the same as Blooio?
Twilio does not operate a public iMessage API. Blooio is a purpose-built iMessage REST API with dedicated iMessage-enabled phone numbers, webhooks, SDKs, FaceTime and FindMy endpoints, polls, and link-preview control — none of which are available through Twilio.
What is the best iMessage API in 2026?
The best iMessage API in 2026 is the one that ships unlimited iMessages on a flat plan, supports RCS auto-fallback, and exposes the full iMessage feature set (reactions, polls, FaceTime, FindMy, link previews) via REST. Blooio scores on all four: $39/mo flat, RCS since launch, every advanced endpoint exposed, and SDKs for Node.js, Python, Go, and Java. Free trial — no credit card.
Can I use the iMessage API with AI agents, Cursor, Claude, or GPT?
Yes. Blooio's webhook system forwards every inbound iMessage to your endpoint, so you can pipe messages into OpenAI, Anthropic Claude, or any LLM and reply via a single API call. Many teams pair Blooio with n8n, Make, or Cursor agents to run an AI-powered iMessage agent in under an hour. Total cost for most setups is Blooio $39/mo plus your LLM provider's usage.
Is there an affordable iMessage API for developers?
Yes — Blooio is the most affordable iMessage API for developers in 2026. The $39/mo shared plan includes unlimited iMessages, a dedicated iMessage-enabled phone number, webhooks, SDKs for Node.js, Python, Go and Java, and every advanced feature (polls, FaceTime, FindMy, RCS fallback). There are no per-message charges and no usage tiers to climb.
How does the Blooio iMessage API compare to Sendblue, LoopMessage, and Linq?
Blooio is flat-rate with unlimited iMessages from $39/mo; Sendblue and LoopMessage are tiered with overage fees and Linq is invite-only enterprise. Blooio also covers polls, FaceTime, FindMy, custom link previews, and a native GoHighLevel integration that competitors don't ship. Detailed head-to-head pages: blooio.com/alternatives/sendblue, /alternatives/loopmessage, /alternatives/linq.
Can I send iMessages from a CRM like HubSpot, Salesforce, or GoHighLevel using the API?
Yes. For GoHighLevel, Blooio is in the GHL marketplace as a first-party iMessage channel — no Zapier bridge required. For HubSpot, Salesforce, Attio, and Pipedrive, use the REST API directly, an n8n/Make/Zapier flow, or one of the SDKs. Inbound iMessages route to your CRM via signed webhooks.
