I'm trying to retrieve greater than 500 records from the GET volumes REST call. If I set the maxRecords query parameter to a number greater than 500, I always get 500 records. However, the query will be adjusted downwards if I place a number less than 500.
This is as per design. at the most, you can fetch 500 records. this is done considaring many factors. one of them is performance. still, if you wanted to have maxrecords more than 500, please get touch with product management.
