Authorization means granting an application the permission to call an API operation. To call API operations, applications must be authorized.

  • When you purchase an API operation in Alibaba Cloud Marketplace, you can authorize your own applications to call the API operation. If you do not have your own application, you can use the application that is automatically created and authorized for you to call the API operation. For more information, go to the Alibaba Cloud Marketplace console.
  • If you and a partner reach an agreement that you can use an API operation that is provided by the partner, authorization must be performed by your partner, namely, the API provider. You must create your own application and provide the ID of the application for the API provider to authorize your application.
