New Shiny API in Google Analytics
New features have been unrolling in Google Analytics since August when version 3 was launched.Google Analytics was in need of a new API and now developers have delivered it.
Data Export API has now been replaced by Google Analytics Core Reporting API which is right now the hot cake for Google Analytics Developers. The current Analytics API is both the continuation of the previous API and not to mention the Javascript Client Library which is currently in Alpha.
The two versions that are currently available in Core Reporting API are Version 2.4 and Version 3.0. The latter version contains new libraries for languages like PHP, Ruby and Python whereas former version is legacy release to maintain compatibility with the previous versions.
Significant changes are available in version 3.0 PAPI starting with authentication through the OAuth 2.0 format, but also in the use of JSON(Javascript for Object Notation) format for data output and absolutely no backwards compatibility with the previous version 2.3. The API team recommends the developers to migrate to 3.0 version.
If custom apps or interfaces are developed using 2.3 API,it needs to be updated within 6 months. Data Export API,XML requests and configuration will not be available at that time.
JSON(Javascript Object Notation) will be replacing XML as the preferred format for returning data.The new features will continue to roll out in 2012 as announced by Google and developers will be working on the API to make the new features more accessible.
