Establishing session for Acumatica web services - web-services

Question

Establishing session for Acumatica web services
I have a requirement where a session is to be established using web services, and then use that session to perform subsequent actions. E.g. Creating SOOrder and Shipment using web services using a previously created session/token.
SOOrder.Screen content = new SOOrder.Screen();
content.Url = InstanceUrl + “/Soap/SO301000.asmx";
content.CookieContainer = new System.Net.CookieContainer();
SOOrder.LoginResult lresult= content.Login(Username, password);
Using this, I have already obtained a session in lresult.Session.
Now, I would like to use this session in below shipmentcontent without calling login again.
SOShipment.Screen shipmentcontent = new SOShipment.Screen();
shipmentcontent.Url = InstanceUrl + "(W(3))/Soap/SO302000.asmx";
shipmentcontent.CookieContainer = new System.Net.CookieContainer();
shipmentcontent.Login(Username, password);

By package various screens in Web Services (SM.20.70.40) found under System -> Integration -> Configure -> Web Services you create a single end-point for all these screens. Consume this service end-point in you app, login only once and call out to all those screens.
thnx

If I understand you corectly you want to persist your login connection between different actions in Acumatia. In order to achieve this, I used the following approach:
Create graph:
public class Importer : PXGraph
{
}
Inside graph created following code:
public string GetHostUrl()
{
var nextIndex = HttpContext.Current.Request.Url.ToString().IndexOf("/", 7, StringComparison.Ordinal) + 1;
var urlStart = HttpContext.Current.Request.Url.ToString().IndexOf("/", nextIndex + 1, StringComparison.Ordinal);
var url = HttpContext.Current.Request.Url.ToString().Substring(0, urlStart);
return url;
}
public Screen Screen
{
get
{
var context = new Screen
{
CookieContainer = new CookieContainer(),
AllowAutoRedirect = true,
EnableDecompression = true,
Timeout = 1000000
};
var nextIndex = HttpContext.Current.Request.Url.ToString().IndexOf("/", 7, StringComparison.Ordinal) + 1;
var urlStart = HttpContext.Current.Request.Url.ToString().IndexOf("/", nextIndex + 1, StringComparison.Ordinal);
context.Url = HttpContext.Current.Request.Url.ToString().Substring(0, urlStart) + "/Soap/IMPORTET.asmx";
return context;
}
}
and then between different screens shared context of the Screen.
For example like this:
var scr = Screen;
var userName = PXAccess.GetUserName();
var password = GetUserPassword();
var context = Screen;
var lgRes = context.Login(userName, password);
but I preserved user password between different sessions
