Payment ID

Technical definition

A unique identifier that tracks the flow of money through the programmatic supply chain, making it possible to reconcile who got paid what for each impression.

The ADLINGO translation

The identifier that makes programmatic money traceable. Every impression generates a payment record. In theory, you can follow that record through the supply chain and reconcile what each party received. In practice, most buyers never look at payment IDs unless something breaks. When something breaks, this is where the investigation starts.
