1. The third-party application initializes parameters, such as the account and password.
2. The third-party application sends an authentication request carrying initialized parameters to API Gateway.
3. API Gateway sends an authentication request to the Cloud USG.
4. The Cloud USG sends a proxy authentication request to the WeLink SSO.
5. The WeLink SSO returns a message indicating that the authentication is successful.
6. After the authentication is successful, the Cloud USG generates a token and returns it to API Gateway.
7. API Gateway returns the received token to the third-party application.
