As some of you know, I've written a pair of modules dealing with the Google client API library. I've just submitted an issue to review the module that supports OAuth 2.0 service account connections and promote it to full module status. The issue is at https://www.drupal.org/node/2569277 which points to the project. The module is designed to deal with updates to the Google client library. It's used by my sandbox module, Google Calendar Merge, at https://www.drupal.org/sandbox/vgriffin/2390267 which allows a user to import data from Google calendars as individual events. Both of these modules are in use on a production web site. I'd really like reviews and feedback. I do intend to make them and my other module (Menu Auto Display) available on Drupal 8.
Thanks!
