What is a seat ID?
A Seat ID is a unique number, that identifies an advertising buyer on OpenRTB. It is usually used to authorize a particular buyer or set of buyers to buy in particular inventory, through Deals.
All organizations in mediasmart have their own Seat ID that you can copy and paste from the organization area in your account.
Do you need a Seat ID or not to bid on a Private Deal?
It depends on the AdExchange/SPP.
For all the exchanges, except Google and Xandr (Microsoft), we always bid with a specific seat ID for all the campaigns you run within your organization.
The SSP/exchange will match any Deal IDs created for you with the Seat ID assigned to you in our system.
This is a Seat ID created by us, and bidding with it does NOT mean these exchanges will invoice you directly.
Our support team or your account manager can provide it.
In the case of Google, you should use mediasmart's account id:
78538159to connect the inventory to the DSP.
