Authentication Mode Selection

API Providers

The following authentication methods are available for calling APIs:

• App authentication (recommended)

  API callers will be authenticated using the AppKey and AppSecret issued by APIG.

  1. This authentication mode is provided for APIG tenants.
• IAM authentication
  Token and AK/SK authentication is supported.

  • Token authentication: Requests are authenticated using a token. This authentication mode is recommended because it requires no SDK signatures.
  • AK/SK authentication: Requests are signed using an AK and SK in the same way as in app authentication mode.

  This authentication mode is provided for APIG tenants.

• Custom authentication

  You can compile a function in FunctionGraph and use it for authentication. For details about API calling, see Creating a Function for Frontend Custom Authentication.

• None

  APIs with None authentication require no authentication of users accessing these APIs.

  1. It is intended for all public network users.
