You'll need to create a Google App and get an OAuth token.
- Go to https://console.developers.google.com/project
- Create a new project
- Enable the Google Contacts and Google+ API
- Go to API > Credentials and create a new Client ID for a Web Application
- Write the App ID and secret on
config/application.yml
Should look something like this:
GOOGLE_APP_ID: "APP_ID"
GOOGLE_APP_SECRET: "APP_SECRET"
