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 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.
