API Usage Statement

Updated at: Dec 14, 2019 GMT+08:00
  • If the API version is evolved or the API URL is modified, APIs of the earlier version can still be used, but their functions are not enhanced. You are advised to use new-version APIs.
  • During application development based on the APIs, parameters added in response messages and push messages sent by the IoT platform must be compatible or ignored, preventing application processing exceptions because of incompatible parameters. For parameters that cannot be identified, the IoT platform discards the packets without processing them.
  • Before an application calls an API, the device certificate provided by the platform must be preconfigured. You can click here to obtain the platform certificate.
