Allowlist Buyer Seats for a Seller Deal

About buyer seat support

With the August 2017 Release, the Video SSP seller deal workflow supports allow listing of buyers seat from RTB buyer organizations while configuring deals. The list of buyer seats allowlisted would be passed in the bid request to the RTB buyer.

This allows publishers and buying platforms to set controls against particular buyers/advertisers on deals including allowlists etc.

  • Buyer Perspective: Buyers can add or remove buyer seats in RTB buyer organizations.
  • Seller Perspective: Sellers can now assign buyer seats to seller deals who can participate in a deal (allowlist buyer seats).

Both buyer and seller organizations provide reports on the Seat ID (for deals) in the platform.
