Deal ID
A unique identifier a seller generates to represent a specific programmatic deal, private marketplace, preferred deal, or guaranteed buy. The buyer enters the Deal ID in the DSP, which then recognizes matching bid requests and applies the agreed terms. A Deal ID that is not matching is the first thing to check when a PMP is not spending.
