OpenAPI Explorer:View API versions

Last Updated:Jun 21, 2026

Alibaba Cloud OpenAPI uses version numbers to control the API list for major cloud service releases. For example, ApsaraDB RDS supports API version 2014-08-15. The string 2014-08-15 is a version identifier, not a date. This means the API data is always current for that version, not static since the date in the identifier.

Viewing API versions

  1. Log in to Alibaba Cloud OpenAPI Explorer.

  2. Select a cloud service.

  3. On the cloud service page, find the API version on the API Overview page. For example, OCR.

On the API Overview page, use the API Version drop-down list at the top to view and switch between versions. For example, OCR provides two versions: 2021-07-07 (Recommended) and 2021-03-15 (Not Recommended).
