OneNET Studio Application API
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.
OneNET Studio Application API is one of 6 APIs that China Mobile publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
