Let’s Talk Sellers.json and SupplyChain Object

1. A Quick Reminder About Sellers.json and SupplyChain Object

As we mentioned in our June article entitled “All you need to know about Sellers.json and the OpenRTB SupplyChain Object”, the IAB has taken ads.txt a step further by introducing sellers.json and the OpenRTB SupplyChain object. The two technical specifications are meant to be used together. They operate at the SSP-level and are part of the IAB’s continued effort to enhance transparency and trust around who is authorized to sell inventory. 

A refresher on the definitions

  • SupplyChain Object: Helps to identify all the players that have participated in the selling or reselling of a bid request. It’s automated and handled by each seller in the chain.
  • Sellers.json: Similar to ads.txt, sellers.json is a public file hosted on an SSP or ad exchange’s corporate website, revealing all the sellers they are working with.
