OneNET Studio Application API is one of 6 APIs that [China Mobile](https://apis.io/providers/china-mobile/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include IoT, Device Management, Thing Model, Platform-as-a-Service, and China. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and authentication docs.

The OneNET Studio application API is the one China Mobile surface with a complete, anonymously readable request-and-response contract. It is an action-dispatched gateway — every call is https://openapi.heclouds.com/{namespace}?action={Action}&version=1, where the namespace is application (application development), common (device management), lwm2m-online or lwm2m-offline. Forty-four operations are documented across devices, products, projects, groups, thing models, device properties and desired properties, thing-model service invocation, device files and scene-linkage rules. Authentication is a signed, time-boxed authorization header (HMAC over et, method, res and version, signature algorithm version 2020-05-29). Every response is a uniform envelope carrying a platform-generated requestId, and business failures arrive as HTTP 200 with success false plus a string error code. China Mobile publishes no OpenAPI for it; the OpenAPI in this repository was transcribed operation by operation from the published reference, with each operation carrying its source page in x-evidence.
