Reports

If you add limit=250000 to your query do you get all of the data? I presume when you say the results are reduced you mean the date range is reduced and not the number of rows returned.

Data from the API is paginated with a default of 10,000 rows and a max of 250,000 rows. For more than 250,000 rows you'll have to also set an offset parameter and run the query again.

You can find details here:
