Is it possible to access a user's Google +1 (Plus One) history via an API?
I would like to access a user's Google Plus One history With +1 enabled, the history is saved in your Google profile and optionally can be displayed: http://www.google.com/+1/button/ It is possible to access this programatically (once the user has given permission via normal Google Authentication and Authorization?) I have only been able to find information for the API to add the button to sites.
You can allways try to parse the data used by G+ itself. The G+ user profile has a tab with all public +1, that can be fetched with https://plus.google.com/_/plusone/get?oid=<google-plus-id> It seems to be related to JSON, but with some differences.
Check this out.... https://developers.google.com/+/history/
Dave, I'm not sure about a user's history, but the count for particular URL is available via a JSON-RPC service (https://clients6.google.com/rpc). Here's a little post on how to: http://www.johndyer.name/post/Getting-Counts-Twitter-Links-Facebook-Likes-Shares-and-Google-Plus-One-Buttons.aspx I'm guessing that same service can get additional data, but I can't find any public documentation either.
