I am really frustrated right now - I have been trying to get this sorted out for a while.
I wrote a very nice CRM for personal use that is based on Google Contacts - at the time I wrote it around AuthSub. Since that has been removed I am trying to update to Oauth2. I can get my auth tokens and everything but I am having no luck accessing my contacts feed.
I get the 405 error "Origin http://nas-crm.domain.us
is not allowed by Access-Control-Allow-Origin." Although this is explicitly set in my API access list.
What do I need to look into or switch over to so I can get this fixed?
