You can map your IAS teams into the system of an ad server or site with Ad Server & Site Mapping in IAS Signal.
IAS pre-maps Account IDs for you wherever possible. If you do not see a mapping in place for your IAS team and partner Account, please create the mapping here.
Login To IAS Signal.
From the left side navigation of IAS Signal, click Tags > Ad Server & Site Mapping.
Search for your ad server or site, and use the Actions dropdown to edit the mapping and add more teams.
Click the + icon to the left of your ad server name to see all IAS teams currently mapped to your ad server. A "MAP" pop up appears.
From the MAP pop up, select the IAS teams to which you want to map.
Click the MAP button.
