Retrieves the data and results for a specific report, including all rows and calculated values. This endpoint returns a maximum of 200 data rows per request. For reports exceeding this limit, use the offset query parameter to retrieve all data through multiple requests. The offset value represents which page of results to return, starting at 0 for the first page. For example, a report with 450 rows requires three API calls: the first with offset=0 returns rows 1-200, the second with offset=1 returns rows 201-400, and the third with offset=2 returns the remaining rows 401-450. Continue incrementing the offset until you receive fewer than 200 rows, indicating you've reached the end of the dataset.
