Tablestore:API overview

Last Updated:Sep 17, 2025

API standard and pre-built SDKs in multi-language

The OpenAPI specification of this product (Tablestore/2020-12-09) follows the ROA 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. Create a Resource Access Management (RAM) user with API-only access and use RAM policies to apply the principle of least privilege (PoLP). Alibaba Cloud accounts are only used when explicitly required.

To call APIs securely, configure the following:
