API standards and multilingual preset SDKs

The OpenAPI of this product (Vpc/2016-04-28) uses the RPC signature style. We have encapsulated SDKs for common programming languages for developers. Developers can download the SDK to directly call this product's OpenAPI without worrying about technical details. If the existing SDK does not meet your needs, you can use the signature mechanism for self-signing integration. Since the details of self-signing are very complex, it may take around 5 business days. Therefore, we recommend joining our DingTalk service group (147535001692) and conducting signature integration under expert guidance.

Before using the API, you need to prepare your identity account and access key (AccessKey) to effectively access the API through client tools (such as SDK and CLI). For details, see Obtain an AccessKey.

Custom signature scenarios

If your business scenario has special requirements and you need to integrate the API through self-signing, we recommend consulting our technical support team first (DingTalk service group: 147535001692) to obtain professional guidance and ensure efficient integration.

Account and security preparation

Alibaba Cloud accounts have full administrative permissions over all resources. Once an AccessKey is compromised, all associated resources will be at risk of unauthorized access. To ensure security, it is recommended to create a RAM user with only API access permissions and configure its AccessKey, while configuring RAM policies based on the principle of least privilege (PoLP). Use the Alibaba Cloud account only in specific scenarios where Alibaba Cloud account permissions are explicitly required.

IPv6 gateway

API

Title

Description

CreateIpv6EgressOnlyRule Add an egress-only rule for an IPv6 address You can create an egress-only rule to allow ECS instances in a VPC with an IPv6 CIDR block to initiate outbound access to IPv6 endpoints of clients, while preventing IPv6 endpoints of clients from accessing ECS instances in the VPC over the Internet. Invoke CreateIpv6EgressOnlyRule to add an egress-only rule for an IPv6 address.
DeleteIpv6Gateway DeleteIpv6Gateway Deletes an IPv6 gateway.
DescribeIpv6Gateways Query created iPv6 gateways Queries IPv6 gateways created in a specified region by calling the DescribeIpv6Gateways operation.
