Use OpenAPI

API version

OpenAPI Portal uses versions to manage the API operations of cloud services that are made available in different periods. For example, ALB supports API operations of the 2020-06-16 version, in which 2020-06-16 represents the API version instead of a time. This version provides all the latest API operations.

Endpoints

An endpoint provides access to the corresponding Alibaba Cloud service. An Alibaba Cloud service supports both public endpoints and virtual private cloud (VPC) endpoints. Public endpoints are globally accessible whereas VPC endpoints are accessible only within the specified VPC. An endpoint is a URL that specifies information about the service, such as the access protocol, hostname, port, and path. Clients can use the information to access the service. For more information, see ALB endpoints, NLB endpoints, GWLB endpoints, and CLB endpoints.

For specific ALB endpoints, see Endpoints.

User identities

We recommend that you use a RAM user or a RAM role to call API operations. Before doing so, you must grant the required permissions to the RAM user or the RAM role. For more information about identities, see Identities, credentials, and authorization.

API style

The API operations of ALB are called in the remote procedure call (RPC) style. For more information, see API styles.
