Making an API Request This section describes the structure of a REST API request, and calls the IAM API for obtaining a user token as an example. The obtained token can then be used to authenticate the calling of other APIs.
{Endpoint} indicates the endpoint of IAM, which can be obtained from Endpoints. For details about API authentication, see Authentication.
For security purposes, create IAM users and assign them permissions for routine management. IAM user An Identity and Access Management (IAM) user is created using an account and can use cloud services. Each IAM user has its own identity credentials (password and access keys).
User roles are essentially IAM permissions. To authorize IAM permissions, an administrator needs to create IAM users, add them to user groups, and assign policies or roles to the user groups. Users in the user groups also obtain the corresponding permissions.
When using a token for authentication, cache it to prevent frequently calling the Identity and Access Management (IAM) API for obtaining a user token. A token specifies temporary permissions in a computer system.
