Connecting with Exact Online

Hello all,

I try to make a app in Windev20 to connect with the financial program Exact Online. In the beginning i need to make a Authentication request to receive a code, but i tried a lot of things but without any results. [developers.exactonline.com]

////
My last trie is as below;

cMyRequest is httpRequest
cMyRequest..URL = "[start.exactonline.nl];
cMyRequest..Method = httpGet
cMyRequest..User = "xx"
cMyRequest..Password = "xx"
cMyResponse is httpResponse = HTTPSend(cMyRequest)
IF ErrorOccurred THEN
Error(ErrorInfo(errFullDetails))
ELSE
EDT_NoName1 = cMyResponse..Content
END

Mayby anyone with experience in this case?

Thanks,
Sammy
