Proficy Operations Hub REST APIs is one of 4 APIs that [GE Vernova](https://apis.io/providers/ge-vernova/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Industrial, IoT, Telemetry, and MQTT. The published artifact set on APIs.io includes an API reference and API documentation.

Two REST surfaces on an Operations Hub installation. The integration APIs let a third-party server authenticate, pull rows from the M2M_data entity, and read or insert rows in any custom entity. The M2M device APIs let sensors and gateways log in, publish telemetry, and subscribe for commands over plain REST POST with JSON payloads. Operations Hub also ships an MQTT client with a defined topic namespace.
