When trafficking a Campaign and/or Line Item, you have the option of setting a Frequency Cap to restrict the number of times a particular ad will be shown to a particular user.   Frequency is typically determined by the ID found in the bidRequest.user.buyeruserID or device.ifa openRTB fields, which correspond to the Beeswax cookie ID on web traffic, and the mobile device ID on in-app traffic. For web traffic that does not have a cookie ID, we will fall back to the device ID if present. Additionally, Beeswax has optional support for enhanced frequency capping on IP Address, IDFV, proprietary customer IDs, and cross device IDs.

Beeswax allows our customers to frequency cap on identifiers besides a Beeswax cookie ID (in Web environments) or a Device ID (in mobile app, mobile web where there is no cookie ID present, and/or Connected TV environments). This can include a full (non-truncated) IP Address, a Customer ID, or a Cross Device identifier, each of which will be read or mapped from the bid request. Beeswax also supports using multiple IDs as a ‘fallback’ mechanism.
