API standard and pre-built SDKs in multi-language
This product (Vpc/2016-04-28) OpenAPI adopts an RPC-style signature mechanism. For implementation details, please refer to the Signature Mechanism documentation.To streamline development, we provide official SDKs for major programming languages. Using the SDK allows you to call APIs directly without worrying about low-level details such as request signatures, significantly lowering the barrier to entry and reducing integration complexity.
Custom signature
If your use case requires direct API integration with custom signatures, consult our technical support team first. Join our DingTalk support group (147535001692) to receive expert guidance.
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.
