User IDs etc.
I'm trying to sync my Zotero library with an online database builder called Heurist. To do so I need to enter my library's "Title,UserID,GroupID,Key, separated by | eg. Artem's library,1958388,268611,YjUxZzcgq1fhCd9YyxgzzVNX | Ian's library,1836383,274864,DuFHBTyVYVhuIhttUotyqBSjb", as suggested on the help page. Any ideas on where I might find these details?
