How Do I Choose an Authentication Mode

API Providers

You can choose any of the following authentication modes:

• App authentication (recommended)

  Simple and non-simple authentication is supported.

  • Non-simple authentication: Requests are authenticated using the key and secret of an integration application.
  • Simple authentication: Requests are authenticated using an AppCode.

  App authentication supports IP-based API access control.

• 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 authenticated using an AK/SK. Request signing is similar to that of App authentication.

  IAM authentication supports IP- and account-based API access control.

• Custom authentication

  If you want to use your own authentication mode, you can create a function backend as your authentication service.

  Custom authentication supports IP-based API access control.

• None authentication

  APIs can be accessed without authentication.

  This authentication mode supports IP-based API access control.
