DescribeActivations - Elastic Compute Service - Alibaba Cloud Documentation Center

Queries existing activation codes and their usage information.

Operation description

Usage notes

You can use one of the following methods to check the responses:

Method 1: During a paged query, when you call the DescribeActivations operation to retrieve the first page of results, use MaxResults to specify the maximum number of entries to return in the call. The return value of NextToken is a pagination token, which you can use in the next request to retrieve a new page of results. When you call the DescribeActivations operation to retrieve a new page of results, set NextToken to the NextToken value returned in the previous call and set MaxResults to specify the maximum number of entries to return in this call.
Method 2: Use PageSize to specify the number of entries to return on each page, and then use PageNumber to specify the number of the page to return. You can use only one of the preceding methods. If you specify MaxResults or NextToken, the PageSize and PageNumber request parameters do not take effect and the TotalCount response parameter is invalid.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
