Hi Mario,
Thanks I really appreciate your fast answer. And I joined the mailing list :)
I have tried using a basic authentication yes, Soup.AuthBasic (I hope this is the one that I should use though).
The repo you sent me is the right one yes, I created a branch called
switch where I pushed my attempts. You need to change the user and password for trying it.
I think the Basic authentication should be good enough. I think my issue is that my request authenticating is correct and returns the right answer, but it seems like I cannot "keep the authentication alive" when I perform the POST request requiring the authentication.
I tried in SoapUI, having 2 requests: one for the authentication and the second doing the POST, and I get some JSON content, as expected.
Thanks for your support.
