Authentication

Typical Scenario

This API is called by an NA for access authentication when the NA accesses open APIs of the IoT platform for the first time. After the authentication of the NA expires, the NA must call this API to perform authentication again so that the NA can continue to access open APIs of the IoT platform.

API Function

This API is used by an NA to get authenticated before accessing open APIs of the IoT platform for the first time.

Note

The authentication API is the prerequisite for calling other APIs. Except the authentication API itself, other APIs must use the accessToken obtained by the authentication API.

If the access token is obtained for multiple times, the previous access token is invalid and the last access token obtained is valid. Do not obtain the access token through concurrent attempts.
