Today, we're excited to announce the release of the Spreedly JSON API beta, combining the benefits of our battle-tested XML API with a modern serialization format. JSON has many benefits, including a more concise serialization format, better human and machine readability, and is, in general, the preferred format for modern APIs. JSON parsers are well-supported in any language making implementing a JSON API client trivial. 

We encourage everybody to upgrade to the JSON API and provide a very simple upgrade path: each endpoint's XML and JSON version is interchangeable. A transaction created with the XML API can be retrieved by the relevant _show_ JSON API endpoint and vice versa, allowing you to incrementally upgrade at the pace and path you feel most appropriate for your service. 

We've also taken the opportunity to update our reference documentation to a more concise format. You can find them here.With this addition we‚Äôre continuing our goal of providing a modern financial platform for our customers, letting you quickly integrate with a variety of backend payment processors. 

Please participate in our public beta of the JSON API today and contact us if you have any questions.
