How to Get Daily Spend Per Region via Taboola API?

Hello,

I'm trying to create an API request that returns daily spend data per region (e.g., U.S. states) using the Taboola Backstage API.

I attempted the following endpoint:

https://backstage.taboola.com/backstage/backstage/api/1.0/{account_id}/reports/campaign-summary/dimensions/region_breakdown
However, it only returns total spend per region for the selected date range—not broken down by day.

I also noticed that it's not possible to combine multiple dimensions like campaign_day_breakdown and region_breakdown, nor can I filter by specific region (only by country).

My goal is to get daily spend data by U.S. state. Is there a supported way to achieve this using the API?
