Pinterest blocks API and breaks third-party Windows Phone apps

Readers alerted us to the disappearance of Pinsation, a third-party Windows Phone Pinterest app, from the Marketplace. While it has almost become the norm for apps to mysteriously vanish from public view without explanation, it was odd to see such a well received app disappear when apps with familiar functionality remain.

We contacted the developer of Pinsation, Daniel Gary, for any details surrounding the disappearance and were told something that sounded awfully similar to issues we've covered previously. According to Gary, Pinterest has locked down their API to prevent access from third-party apps on any platform other than iOS.

There problem occurs when you try to login to the service using Facebook or Twitter. In short, you'll receive and authentication error telling that there was an issue logging you in. The app spits you back to browsing the Pinterest site but you are unable to do so logged into an account (we imagine authenticated accounts, done by invite only, may still work).

Gary also mentioned that developers are working together to try and find a solution to this issue. For the time being you may encounter problems when attempting to use Pinterest apps on Windows Phone (or other platforms).

We'll keep you guys up-to-date with any further information we receive / find out.
