NewsGator has had a web API using SOAP for some time.  It’s been very popular – it’s used in our own clients (NewsGator Inbox, FeedDemon, and NetNewsWire), third party clients such as RSS Bandit, and private label customers (online, but unlaunched as of yet). We currently process millions of API calls per day in our online system, and the API is also implemented in NewsGator Enterprise Server.

There has been quite a bit of feedback from developers about the API; most of this feedback centered around the lack of a REST version of the API.  We’ve found that some developers have never used SOAP, and there is a learning curve on certain platforms to learn a SOAP toolkit; other developers just don’t want the extra complication in the messages, and prefer a REST solution.

Whatever your reasoning, though, you can now choose for yourself. We now have both SOAP and REST versions of the NewsGator Online API available.  The SOAP version has been around for a while, and is used by our own products.  The REST version is brand new, is documented here, and enters a public beta today.  So try it out, and let us know what you think – we’re looking for feedback!
