DescribeSnapshots - API Reference| Alibaba Cloud Documentation Center

Description

You can specify multiple request parameters such as InstanceId, DiskId, and SnapshotIds to be queried. Specified parameters have logical AND relations. Only the specified parameters are included in the filter conditions.

When you call an API operation by using Alibaba Cloud CLI, you must specify request parameter values of different data types in required formats. For more information, see CLI parameter formats.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
