To send a Virtual Private Cloud (VPC) API request, you must send an HTTP GET request to the VPC endpoint. You must add the request parameters that correspond to the API operation being called. After you call the API, the system returns a response. The request and response are encoded in UTF-8.
VPC API operations use the RPC protocol. You can call VPC API operations by sending HTTP GET requests.
This topic uses the CreateVpc operation as an example to describe an unencoded URL request:
https://vpc.aliyuncs.com/?Action=CreateVpc &RegionId=cn-hangzhou &<Common Request Parameters>
httpsspecifies the protocol for transmitting the request.
VPC API operations support communication over the HTTP or HTTPS protocol. For security purposes, we recommend that you send requests over HTTPS.
vpc.aliyuncs.comspecifies the endpoint of VPC.To minimize network latency, we recommend that you specify the endpoint based on the region where you call API operations. The following table lists the endpoints of the VPC API.Note For regions that are not listed in the following table, use
Region Endpoint Default vpc.aliyuncs.com China (Zhangjiakou-Beijing Winter Olympic) vpc.cn-zhangjiakou.aliyuncs.com China (Hohhot) vpc.cn-huhehaote.aliyuncs.com China (Ulanqab) vpc.cn-wulanchabu.aliyuncs.com China (Chengdu) vpc.cn-chengdu.aliyuncs.com China (Heyuan) vpc.cn-heyuan.aliyuncs.com China (Guangzhou) vpc.cn-guangzhou.aliyuncs.com Japan (Tokyo) vpc.ap-northeast-1.aliyuncs.com Germany (Frankfurt) vpc.eu-central-1.aliyuncs.com UAE (Dubai) vpc.me-east-1.aliyuncs.com Australia (Sydney) vpc.ap-southeast-2.aliyuncs.com Malaysia (Kuala Lumpur) vpc.ap-southeast-3.aliyuncs.com India (Mumbai) vpc.ap-south-1.aliyuncs.com Indonesia (Jakarta) vpc.ap-southeast-5.aliyuncs.com UK (London) vpc.eu-west-1.aliyuncs.comNote VPC endpoints use public service addresses. If the Elastic Compute Service (ECS) instance in your VPC cannot access the Internet, you cannot call API operations by using Alibaba Cloud CLI or SDKs. To call API operations over VPCs, see Call API operations over a VPC.
Action=CreateVpcspecifies the operation that is being called.
RegionId=cn-hangzhouis a required parameter of the CreateVpc operation.
<Common request parameters>are common parameters defined in the system.
