We’ve now added JSON support to the FogBugz API in FogBugz On Demand.
This means that you can both send and receive JSON from the FogBugz API. It has been implemented as a wrapper around the existing XML API but with a new endpoint, so all commands are supported. For those of you who have worked with our XML API before, there are a few differences to be aware of. But otherwise, check out the documentation for a full list of supported API commands and arguments.
To give you some idea of the power of the FogBugz API, check out our integrations list to see what has already been created with the API, and get inspired to work with the FogBugz API yourself.
