Queries the details of a group.

Limits

Each Alibaba Cloud account can run a maximum of 30 queries per second (QPS).

Note RAM users of an Alibaba Cloud account share the quota of the account.

Debugging

Alibaba Cloud provides OpenAPI Explorer to simplify API usage. 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.
