The router interface and leased line you created are your own resource. By default, you have full operation permissions on your resources, and you can use all APIs described in this document to operate on your resources.

You can use your Alibaba Cloud account to create RAM users, and an unauthorized ram user cannot operate on resources of the Alibaba Cloud account. You must grant the permission to the RAM user to operate on resources of the Alibaba Cloud account by the RAM authorization.

Make sure that you have read the RAM and API carefully before you use RAM to authorize access to router interface and leased line.

Skip this section if you do not need to grant an RAM user to access Express Connect resources in an Alibaba Cloud Account. Skipping this section does not affect your understanding and usage of the Express Connect API.
