Who is Bonapitit for?
Bonapitit has been designed to be easy to migrate to from an existing eBay application, and easy to get started with if you don't have an application. Bonapitit can currently accept input in either JSON or XML format, with output being in JSON. Most web languages have deep support for parsing JSON, as it is a more uniform standard than similar choices such as XML.
Note that, while Bonapitit is currently being used by a number of different services (and we have built an automated testing suite to support it), there may still be some occasional bugs. Please report these with as much detail as possible to api@bonanza.com and we'll work to get them resolved as quickly as we're able.
