As a network client
As a network client, each advertiser has a different Revenue Origin ID, and it can be found on the advertiser detail in the Advertiser list, in the Advertiser ID section.
You can also find it in the offer's Postback/Integrations section, where the Revenue Origin ID is relevant for the tracking, specific to the advertiser that owns the offer.
