I am an Admin in Adobe Campaign, Audience Manager, Audience Library, the Custom Audience Manager Group, and also in the Adobe Campaign Experience Cloud profile. But I am still getting this permissions error when I try to import an audience from the Experience cloud.
I'm not sure what you mean by Web Servers. This integration was for People Core Services from ACC to AAM, which used the exp. cloud to pass the data. The documentation doesn't mention the Named Rights in Adobe Campaign. Which I was already an Administrator, but I needed to add these additional ones.
In Adobe Campaign Classic, I added a few named rights and that seemed to do the trick. Everything for the AAM was good to go.
I understand that you have Admin on those products do you also have Web services? Where is the sharing coming from is it a segment that is the Experience Platform? You should have Web Services access from Analytics, Admin access in Analytics, Access to Shared Audiences, And then your groups in Campaign. Sounds like its just about there. Can you confirm your access?
