Google+ Direct Connect
Google+ Direct Connect lets us all get to a Google Plus page (and even add that page to our circles) when using Google Search. If you searched for the query '+youtube' or '+pepsi,' you could be immediately taken to the YouTube Google+ page, or the Pepsi Google+ page, and given the option to add the page to your circles.
The first integration points are becoming available for us in the know to sample. This initial set is focused on providing read access to public data. We’ll be adding more APIs over time to build on this foundation and help you create more types of integrations. This initial release is intended for feedback and learning — they are restricted to a courtesy usage quota and some functionality is disabled. This should provide enough access for you to check out the APIs and to start integrating Google+ with your apps. You can request more quota at the Google+ API Console. We’ll keep a close eye on feedback, and will release more APIs into production as soon as they’re ready. So go ahead and start building!
The Google+ API is the programming interface to Google Plus You can use the API to integrate your app or website with Google+. This enables users to connect with each other for maximum engagement using Google+ features from within your application.
Applications are limited to a usage quota. Luckily I know the right people..This should provide enough access for the accounts that matter to preview the API and to start thinking about how you want to build your application. To see the courtesy limit and to request a higher limit for your application, please see the Google APIs Console. To learn more, see the Google APIs Console Help.
Many API calls require that the user of your application grant permission to access their data. Google uses the OAuth 2.0 protocol to allow authorized applications to access user data. To learn more, see OAuth.
Most of the Google+ API follows a RESTful API design, meaning that you use standard HTTP methods to retrieve and manipulate resources. For example, to get the profile of a user, you might send an HTTP request like: GET https://www.googleapis.com/plus/v1/people/userId
Different API methods require parameters to be passed either as part of the URL path or as query parameters. Additionally, there are a few parameters that are common to all API endpoints. These are all passed as optional query parameters.
