Hi Frank,

Calling HTTP endpoints from FoxPro is fairly straight forward. There are several libraries out there that provide that through WinInet or WinHttp. West Wind has the wwHttp class (as part of West Wind Client Tools) which makes HTTP calls super easy, including the file uploads mentioned in your API and ability to use all HTTP verbs for requests.

The West Wind Client Tools also include a wwJsonSerializer class that can parse just about any type of JSON into a FoxPro object. It uses a popular .NET JSON parser behind the scenes so it's very capable in terms of what it can deal with (unlike my own and some other FoxPro based implementations which are slow somewhat unreliable with very complex JSON).

wwHttp Class Reference:

Some Http Examples:
Basic Http Access

Uploading Files:

wwJsonSerializer Class Reference:

Holler if you have questions - it's usually quicker if you hit our West Wind Message Board - but I check here on occasion as well.
