Hi,

I should have sent a UBL 2.1 file via API POST via Createobject("MSXML2.XMLHTTP.6.0")

How and if it can be translated into VFP via Createobject("MSXML2.XMLHTTP.6.0") (not to "twist" the curl into some *.bat file and send it. It can, it works.).
Also, it works quite nicely if sent via C #. That's how I solved it, but I don't succeed via VFP using Createobject("MSXML2.XMLHTTP.6.0")


Below is the result of the PostMan:
