I haven't played around too much before with API's and JSON but how would one go about retrieving data from these.
Should there not be a URL that hosts this web service or API? The examples of that page just provide info of the data sent. No information on how to integrate the API's
Also, how would myprosperity know who is retrieving the data.
e.g. If my friend wants to pull just his clients, there must be some kind of authentication that happens surely?
