XING has recently decided to discontinue its official free API.
Today we are introducing the better alternative – new NextScripts Premium API for XING. Unlike the API from XING that was able to make posts to profiles only, NextScripts Premium API for XING can post to profiles, company pages, and groups.
All current API subscribers are getting it for free today. SNAP WordPress Pro plugin users can use it starting from version 3.7.16 (API 2.27.0). SNAP Pro API and SNAP Light API users should download package version 28 (API 2.27.0)
