We recommend you start by trying to connect to the dummy API. The methods in the dummy interface return test data as detailed in each of the methods in the left window.
Each method must contain your access key as the first parameter. For testing purposes please use the id: 'guest'. All the results for the dummy version are fixed, although some parameters (e.g. the access key) are checked for validity.
You may access the dummy XML-RPC server here:

Please follow one of the tutorials for further instructions.
