curl -u "correctUser:correctAPIKEY" \
 -X GET \
 -H "Accept: application/json" \
 -s -o response.json -w "%{http_code}\n" \
 ";

returns status code 200 and a list of project within the result json.

curl -u "missingOrIncorrentUser:missingOrIncorrentKey" \
 -X GET \
 -H "Accept: application/json" \
 -s -o response.json -w "%{http_code}\n" \
 ";

Still returns 200, at least for me? What is the logic behind it? What happend to 403 and 401?
