API overview
API standard and pre-built SDKs in multi-language
The OpenAPI specification of this product (Vpc/2016-04-28) follows the RPC standard. Alibaba Cloud provides pre-built SDKs for popular programming languages to abstract low-level complexities such as request signing. This enables developers to call APIs using language-specific syntax without dealing with HTTP details directly.
Custom signature
If your specific needs, such as a customized signature, are not supported by the SDK, manually sign requests using the signature mechanism. Note that manual signing requires significant effort (usually about 5 business days). For support, join our DingTalk group (ID: 147535001692).
Before you begin
An Alibaba Cloud account has full administrative privileges. A compromised AccessKey pair exposes all associated resources to unauthorized access, posing a significant security risk. To call APIs securely, create a Resource Access Management (RAM) user with API access only, configure its AccessKey pairs, and implement the principle of least privilege (PoLP) through RAM policies. Use the Alibaba Cloud account only when its permissions are explicitly required for specific scenarios.

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 | Invoke the DescribeIpv6Gateways API to query IPv6 gateways created in a specific region. |
