Artera Messaging API (MAPI) is one of 2 APIs that [Artera](https://apis.io/providers/artera/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Messaging, SMS, Patient Communication, Healthcare, and Webhook. The published artifact set on APIs.io includes API documentation, an API reference, and authentication docs.

Artera's outbound SMS API, marketed to health systems and Artera Marketplace vendors as the SendMessage API. It sends real-time text messages to patients from the health system's trusted Artera number, authenticated with OAuth 2.0 plus an API key and restricted by IP allowlist. It optionally returns a Deliverability Webhook carrying the message status (received, sent, delivered, undelivered, failed) and a Patient Response Webhook when a patient replies through the Secure Messaging Portal. MAPI is SMS-only — not voice or email — delivers immediately with no advance scheduling, permits and auto-shortens URLs, and deliberately does NOT apply Artera's TCPA quiet-hours or Holiday Hours adjustments, leaving send-time compliance to the caller. The full specification is published only inside Artera's registration-gated developer portal.
