CloudOps Orchestration Service:API overview

Last Updated:Jan 07, 2026

API standard and pre-built SDKs in multi-language

The OpenAPI specification of this product (oos/2019-06-01) 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.
