Microsoft Curate - Working with advertisers

An advertiser is a company, agency, or other grouping that displays media creatives on publisher web and/or mobile inventory. The Advertiser object is the top level of the buy side of the Object Hierarchy. Setting up the advertiser defines the advertiser's identity as well as some of the buying terms. The advertiser also serves as a container for other objects including insertion orders, line items, creatives, and pixels that you can combine to begin buying digital inventory.
