I am using the Multi-Channel API from Google analytics to access a custom assisted conversion report which uses the channel groupings I defined.
Since the custom channel groupings aren't accessible themselves through the API, I sought to reproduce them using filter. For example, this group
Bank referral := source contains "bank"
translates to
filter=mcf:source=@bank
however the API keeps returning me assisted conversions bigger than what is displayed in Google Analytics. Does anyone know how I can solve this?
