Get attachment via SOAP

[jcosta]

Hello!

I'm trying to get an attachment via SOAP but i'm not getting there. I'm allways getting "Unauthorized".
I've tried basic authentication with a normal user and admin. Replaced the token for a password.
I've tried with a cookie with a normal user and admin. Replaced the token for a password.
None of this work. Can you help me please?

HttpWebRequest retVal = (HttpWebRequest)WebRequest.Create("http://" + @DOMAIN + "/service/content/" + "get?id=" + id + "&part=" + part + "");
retVal.Method = "GET";

Basic authentication

string authInfo = AccountUsername + ":" + AuthToken;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
retVal.Headers["Authorization"] = "Basic " + authInfo;

Cookie

CookieContainer cookieJar = new CookieContainer();
Cookie c = new Cookie("ZM_AUTH_TOKEN", AuthToken);
c.Domain = @DOMAIN;
cookieJar.Add(c);
retVal.CookieContainer = cookieJar;

retVal.GetResponse()

Hello again!
Via fiddler, i've scan the response and everything looks ok with the request.
The response is still "Unauthorized".
Analysing the reponse i've discovered the reason why. "Unable to parse authtoken".
I checked the token and it's all good.
Searched the internet and i can't find any answers.
Can anybody help me please?

ZM_AUTH_TOKEN=0_65b753c79755637b23820a57773d343db821d5bf_69643d33363a33303637333634392d313931392d346138362d626363322d3639333863306562313737333b6578703d31333a313334383233343236303531383b76763d313a353b747970653d363a7a696d6272613b
