Basis/Centro DSP
In Basis, you have to add the FouAnalytics in-ad tag to EACH creative. You do that when you set up each creative. See the highlighted portion below. Copy and paste an in-ad FouAnalytics tag into the "Script Impressions Tracking URL" field. Note that it is the bare JS tag type and if you've selected the Basis macros, those will be appended for you.
