Text Message API - Technical Specification

Overview

Wunderkind’s Text Message API is a set of REST endpoints that let you send SMS/MMS from external systems (e.g., ESP/CDP), retrieve message status, and manage subscription state — secured with simple header-based authentication.  These allow clients to:

1. Send text messages through the Wunderkind platform
2. Call the status of the sent text message
3. Check the subscription status of a user within the Wunderkind text program
4. Unsubscribe a user (or group of user's) from the Wunderkind text program
