It would be GREAT if you updated your API to allow us to pass Row #s to delete in the body of the API call rather than in the URL. Because of the length limitation of a URL, I can only delete around 300 rows at a time via the API. However, if I could pass all 20,000 rows in the body of the call, I could easily clear the sheet in a single call rather than having to iterate and make 60+ calls.
