Hi, i'm building a generic reporting tool, and want to include adword reporting on behalf of my (hypotetical) clients. The idea is for the tool to be a unified dashboard for all of the advertiser account the client/agency uses, such as google adwords, facebook ads, twitter ads, appnexus and others.
I know i can make the client obtain a developer token, but there is a strong warning about allowing it to be used by third parties. Is there a way to create an app and have the client delegate the necessary permissions? FB does this for example.
If not, will i be going the ToS if i request their developer token?
Thanks a lot!
