I can't seem to get this working.
I go through the configuration as explained, adding plugin to WordPress, configuring under Settings: Google crossposting.
Add in the Google+ ID (but just the long number, not the entire link) and then created an API Key.
That all seems to be fine.
But I cannot seem to get a post, posted.
not sure what to do...if it is theme related, improperly set up API, etc
