How does the Token refresh mechanism work?

We don’t refresh Access Tokens automatically. Developers initiate Access Token refreshes in these scenarios:

  1. Configure the Access Token’s validity period in the Console, defaulting to permanent. For subsequent logins, skip requesting a Access Token from Nexconn. The App Server provides the saved Access Token directly.

  2. After refreshing the App Secret in the Console, previously obtained Access Tokens become invalid. Use the new App Secret to generate a signature and retrieve a new Access Token.

  3. The App Server calls Nexconn API to get an Access Token. For the same User ID, you can retrieve a Access Token multiple times. Access Tokens remain valid within their validity period and expire afterward, requiring a new retrieval.
