Google has announced the launch of the brand new Google Analytics Metadata API which returns the list and attributes of columns (dimensions and metrics) generated from the Google Analytics reporting APIs.
Nielsen, the media-measurement juggernaut, announced that it is opening up its API for the first time. Nielsen made the announcement alongside many other groundbreaking launches and promotions as SXSW continues to heat up. With coverage in more than 100 countries, Nielsen maintains a treasure trove of data that developers have long been eager to get their hands on. With the API release, developers can begin to build applications directly off data that is generated and maintained by Nielsen.
Google has announced that Google Analytics now features a new service, the Google AMP Client ID API. The new API makes it possible for developers to analyze user experience across AMP and non-AMP pages, and provides metrics such as bounce rate, session duration, and pages per session.
