Before You Start

API Gateway (APIG) is a high-performance, high-availability, and high-security API hosting service that helps enterprises build, manage, and deploy APIs at any scale.

This document describes how to use REST APIs to perform operations on APIG, such as creating, deleting, and modify your own APIs. For details about all supported operations, see API Overview.

If you plan to access API Gateway through APIs, ensure that you are familiar with API Gateway concepts. For details, see the Service Overview.

V2.0 APIs are provided for the dedicated gateways and V1.0 APIs are provided for the shared gateway on the old console. The shared gateway on the old console has been removed. Please use dedicated gateways to manage your APIs instead.

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 and should not be used directly to perform routine management. For security purposes, create IAM users and grant them permissions for routine management.

  • IAM user

    A user is created using a domain to use cloud services. Each user has its own identity credentials (password and access keys).

    An IAM user can view the account ID and user ID on the My Credentials page of the console. The domain 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 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 Regions and AZs.

  • Availability zone (AZ)

    An Availability Zone (AZ) contains one or more physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, compute, network, storage, and other resources are logically divided into multiple clusters. AZs within a region are interconnected using high-speed optical fibers to support cross-AZ high-availability systems.

  • Project

    Projects group and isolate resources (including compute, storage, and network resources) across physical regions. A default project is provided for each Huawei Cloud region, and subprojects can be created under each default project. Users can be granted permissions to access all resources in a specific 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.

    An IAM user can view the project ID on the My Credentials page of the console.

  • 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 how to obtain enterprise project IDs and features, see the Enterprise Management Service User Guide.
