Welcome to Resource Governance Center API Reference. Resource Governance Center (RGC) offers an easy way to set up and govern a secure and scalable multi-account environment. You can use RGC to create a landing zone that contains one management account and multiple member accounts, and configure auto guardrails for these accounts. This helps you quickly and securely migrate services to the cloud.

This document describes how to use application programming interfaces (APIs) to perform operations on RGC, such as creating, deleting, modifying, and querying. For details about all supported operations, see API Overview.

If you plan to access RGC through an API, ensure that you are familiar with RGC concepts. For details, see Resource Governance Center Service Overview.

Endpoints

An endpoint is the request address for calling an API. Endpoints vary depending on services and regions. For the endpoints of all services, see Regions and Endpoints.

Concepts

Account
An account is created upon successful registration with Huawei Cloud. The account has full access permissions for all of its cloud services and resources. It can be used to reset user passwords and grant user permissions. The account is a payment entity, which should not be used directly to perform routine management. For security purposes, create Identity and Access Management (IAM) users and grant them permissions for routine management.
User
An IAM user is created by an account to use cloud services. Each IAM user has their own identity credentials (password or access keys).

The account name, username, and password will be required for API authentication.
Region
Regions are divided based on geographical location and network latency. Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region. Regions are classified into universal regions and dedicated regions. A universal region provides universal cloud services for common tenants. A dedicated region provides specific services for specific tenants.

For details, see Region and AZ.
AZ
An AZ contains one or more physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, computing, network, storage, and other resources are logically divided into multiple clusters. AZs within a region are interconnected by optical fibers for high-availability networking.
Project
A project corresponds to a region. Default projects are defined to group and physically isolate resources (including compute, storage, and network resources) across regions. Users can be granted permissions in a default project to access all resources under their accounts in the region associated with the project. If you need more refined access control, create subprojects under a default project and create resources in subprojects. Then you can assign users the permissions required to access only the resources in the specific subprojects.

Figure 1 Project isolating model
Enterprise project
Enterprise projects group and manage resources across regions. Resources in different enterprise projects are logically isolated. An enterprise project can contain resources of multiple regions, and resources can be added to or removed from enterprise projects.

For details about enterprise projects and about how to obtain enterprise project IDs, see Enterprise Management User Guide.
