Hi John
Here is the real message except the key
Error calling GET
https://www.googleapis.com/webmasters/v3/sites/http%3A%2F%2Fwww.samariter-osv.ch/sitemaps?key=mykey: (403) User does not have sufficient permission for site 'http://www.samariter-osv.ch/'. See also:

To access Google Analytics of my page I use the same account as I entered in Jsitemap. If I push the button Google Analytics in Jsitemap I get all the information the login works fine at this point.
Cheers
