Qty§3.2.31 · Bid Request

A programmatic impression is often referred to as a ‘spot’ in digital out-of-home and CTV, with an impression being a unique member of the audience viewing it. Therefore, a standard means of passing a multiplier in the bid request, representing the total quantity of impressions, is required. This object includes the impression multiplier, and describes the source of the multiplier value.
