Two things for you to try with your VFP solution:

a) the last boundary must be

----WebKitFormBoundary7MA4YWxkTrZu0gW--

(note the two final dashes '--').

b) you must insert a final blank line so that the TEXT .. ENDTEXT construct creates an additional (but required) CRLF.

That is:

----WebKitFormBoundary7MA4YWxkTrZu0gW--

ENDTEXT

Porting the C# code into VFP requires writing a REST class for VFP, similar in specs to the .NET class. I think there are a few classes or functions out there for the urlencoding EncType, adding the multipart EncType wouldn't be too difficult, probably.

I do as you stated, but I get an error:

m.loXMLHTTP.statustext Unprocessable Entity
m.loXMLHTTP.Status 422
m.loXMLHTTP.responseTExt {"status":"failed","error":{"data":["Parametar data je obavezan"],"type":["Parametar type je obavezan"],"sef":["Parametar sef je obavezan"],"contacts":["Parametar contacts je obavezan"]}}


this is xml (part of the file):
