I'm afraid our docs were updated too soon by (my) mistake: the Analytics Client that has the new options for creating Public API Keys was held back a few days but the docs were already updated with the link. We're just in the process of releasing it now. It may be released tomorrow Friday and if not then it will certainly be released at Monday.
I will notify you as soon as it's available and apologize for the confusion.
EQATEC Application Analytics is now Telerik Analytics
. For more information on the new name, plus what's new in Telerik Analytics, please, check out the Analytics Service Announcement
