publisherTargeting property

Targeting on a subset of publisher inventory.

Publishers can either be targeted positively (bid requests will be sent only if the publisher is listed in the targeting dimension) or negatively (bid requests will be sent only if the publisher is not listed in the targeting dimension). A maximum of 10,000 publisher IDs can be targeted. Publisher IDs are found in ads.txt / [app-ads.txt](https://iabtechlab.com/app-ads-txt/) and in bid requests in the BidRequest.publisher_id field on the Google RTB protocol or the BidRequest.site.publisher.id / BidRequest.app.publisher.id field on the OpenRTB protocol. Publisher IDs will be returned in the order that they were entered.
