Admixer HB Wrapper platform interacts with different types of Buyers. Publisher can add PrebidJS and AdServer buyer, while others are added by Admixer.

Prebid JS: This type represents a 3rd-party demand source connected via the Prebid Adapter, with which the publisher has their own signed contract. 

AdServer: This Buyer type is for publishers who have their own Google Ad Manager account and wish to use Google Ad Manager as their ad server. 

Admixer SSP: This buyer, along with its bids, is generated automatically for each added Ad unit. Through Admixer Prebid, publishers receive demand from Admixer direct partners and 3rd-party DSP partners. Publishers can't delete, edit, or unlink this Buyer from their ad units.

Admixer Marketplace: Similar to the Prebid JS buyers, this buyer represents 3rd-party Prebid demand, but the contract belongs to Admixer. These Buyers and their Bids are generated automatically and can't be deleted or edited. However, Publishers can choose not to link these Buyers to their inventory. To view available Admixer Marketplace buyers, go to Ad unit  → Manage bids  →  Available Bids. 

Admixer Goolge Marketplace: This is the analogue of the Ad Server buyer type but under Admixer's contract. To get access to that Buyer, please, contact your account manager.
