If you've ever tried to send an iMessage programmatically , you've probably hit the same wall everyone does: Apple has no public iMessage API. There's no POST /imessage in the developer docs, no SDK, no OAuth scope. Yet "blue bubble" delivery has 3–4× the open rates of SMS, so the demand to send iMessages from code — for CRMs, bots, notifications, and outbound — keeps growing. This guide covers the realistic options, then walks through actually sending and receiving iMessages over a REST API with working Python , Node.js , and curl examples you can paste and run today. Why there's no official iMessage API iMessage is a closed, end-to-end-encrypted protocol tied to Apple IDs and Apple hardware. Apple has never shipped a public API to send iMessages, and "Messages for Business" is a support-inbox product gated behind an approval process — not a way to send outbound messages from a script. So historically, developers reached for hacks: Approach Works from a server? Reliability Receiving messages Notes AppleScript / osascript No — needs a logged-in Mac with Messages open Brittle Polling the local SQLite chat.db Mac-only, breaks on macOS updates Shortcuts automation No Brittle No Manual, not built for scale "Just use SMS" (Twilio etc.) Yes High Yes Green bubbles, no typing indicators/tapbacks/HD media Hosted iMessage REST API Yes High Yes (webhooks) What this guide uses The AppleScript route is fine for a one-off script on your own Mac. The moment you want to send from a server, send at scale, or receive replies reliably, you need a hosted API that manages the Apple side for you and exposes a normal HTTP interface. The setup For the examples below I'm using Blooio , an iMessage REST API. Any provider with a similar HTTP surface will follow the same patterns — the concepts (Bearer auth, a send endpoint, webhooks for inbound) are what matter. You'll need: An API key (Blooio gives you one in the dashboard — no credit card, no A2P/10DLC registration, no DUNS number) A phone

If you send SMS one-time codes, there's a decent chance you're paying scammers to phone-spam themselves on your dime. It even has a name: SMS pumping . And it's not a rounding error — Elon Musk claimed Twitter was losing ~$60M/year to fake 2FA traffic before they killed SMS 2FA for free accounts. Here's how the scam works, why SMS 2FA is structurally expensive, and why flipping the direction — mobile-originated (MO) 2FA , taken to its logical end over iMessage — fixes both the cost and the fraud at once. What is SMS pumping? SMS pumping (also called AIT — Artificially Inflated Traffic , or SMS toll fraud ) is a scheme where bad actors abuse a form that sends SMS one-time codes. They pump thousands of phone numbers — usually premium ranges they secretly control with a telecom — into your "send me a code" endpoint. You pay for every one of those messages. A cut of that termination fee flows back to the fraudsters via the carrier. The "users" never log in. They were never users. The entire point was to make your verification endpoint dial a meter that pays them. The structure that makes this possible is simple: you, the company, send (and pay for) the message. Every code is revenue for someone in the delivery chain — so there's a direct financial incentive to trigger as many as possible. Why SMS 2FA is expensive even without fraud Even with zero abuse, application-to-person ( A2P SMS ) is a bad cost curve: You pay per message. Volume spikes — a launch, a bot attack, an international audience — turn into surprise bills. International is brutal. Cross-border A2P carries steep carrier surcharges that vary wildly by destination. Carrier fees and registration overhead. In the US you're funneled through A2P 10DLC registration, brand vetting, and per-segment fees before you send a single legit code. So your 2FA line item is pay-per-event , unpredictable , and exploitable . Three bad properties for something that's supposed to be boring infrastructure. The Twitter/X case This
