Event Tracker Response§5.8 · Bid Response
The event trackers response is an array of objects and specifies the types of events the bidder wishes to track and the URLs/information to track them. Bidder must only respond with methods indicated as available in the request. Note that most javascript trackers expect to be loaded at impression time, so it’s not generally recommended for the buyer to respond with javascript trackers on other events, but the appropriateness of this is up to each buyer.
