Bidder - Inventory Availability report

Inventory Availability report offers insight into the types of inventory available on the platform. These reports are available by request only; use the support portal. Due to the structure of our impression availability databases, reporting dimensions are limited to those outlined below. Also note:

  • Our databases contain 30 days worth of historical inventory availability data. Reports are therefore limited to this timeframe.
  • Additional reporting restrictions may apply to mobile impressions. Contact your Xandr representative for further information.

You can run this report for a custom time frame, set the start_date and end_date fields in your report request. For more details about these fields, see Report Service.
