Obtaining Initialization Parameters

Authentication Mode

When using the service-plane SDK, you need to prepare the necessary parameters for client initialization in advance. GES offers two authentication modes, and you can choose either one.

Token-based authentication: Obtain a token authentication request using a username and password.
AK/SK-based authentication: Requests are authenticated by encrypting the request body using an AK/SK.

AK/SK-based authentication is recommended as it provides higher security.
