iMessage API FAQ
What is an iMessage API?
An iMessage API lets software send and receive iMessages — the blue-bubble messages Apple users trust — programmatically instead of by hand. Linq offers the only SOC 2 Type II–certified iMessage API, so developers and AI agents can hold real, two-way iMessage conversations with carrier-grade reliability.
Can I send iMessages programmatically? Is there an official Apple iMessage API?
Apple does not offer a public iMessage API. Linq provides the infrastructure to send and receive iMessages programmatically through a developer-first REST API and webhooks — reliable, compliant, and built to run at scale.
Is the Linq iMessage API secure and compliant?
Yes. Linq is SOC 2 Type II certified — the only iMessage API that is. Message content is encrypted and inaccessible even to Linq, which is why security-conscious teams in fintech and beyond can pass procurement and build with confidence.
How is Linq different from Twilio and other SMS APIs?
Linq is iMessage-native — the blue bubble — with no per-message pricing and no metered billing. It’s built for the AI era, where agents hold constant two-way conversations. RCS, SMS fallback, and voice are all included, so you get the reach of a CPaaS with the trust of iMessage.
Does the API support RCS and SMS fallback?
Yes. Linq supports RCS with automatic SMS fallback and voice alongside native iMessage, so your messages reach every device on the channel that works best.
What can AI agents do over iMessage with Linq?
AI agents can start and manage one-on-one and group chats, send and receive rich media, send tapback reactions, read typing indicators and read receipts, place calls with transcription, and schedule FaceTime — everything needed to feel like a human in the thread.
How fast can I integrate the iMessage API?
Most teams send their first message in about five minutes using the sandbox. The full REST API, webhooks, and documentation are available at docs.linqapp.com.
How reliable is the Linq iMessage API?
Linq delivers 99.95% uptime backed by the only contractual SLA in the industry, with <120ms median latency and more than 150M messages processed for over 1,000 teams.
