SVC WS - Logon and message issue

Question

Hi I have a SVC web service which I imported to BizTalk via consume adapter. 
Now, I'm trying to send a message that is suppose to sync the data in this API. 
I buily a multi part message with the Logon request and the Sync Request. 
and I keep getting erros about it. 
Does anyone know how I'm suppose to do it? the logon part and the sync part together?
this is the fault message i'm getting:
<s:Fault xmlns:s="http://www.w3.org/2003/05/soap-envelope"><s:Code><s:Value>s:Sender</s:Value><s:Subcode><s:Value xmlns:a="http://schemas.xmlsoap.org/ws/2005/02/sc">a:BadContextToken</s:Value></s:Subcode></s:Code><s:Reason><s:Text xml:lang="en-US">The message could not be processed. This is most likely because the action '&lt;BtsActionMapping xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
&lt;Operation Name="Logon" Action="http://tempuri.org/IExternalMappingService/Logon" /&gt;
&lt;Operation Name="AddExternalAttributeData" Action="http://tempuri.org/IExternalMappingService/AddExternalAttributeData" /&gt;
&lt;Operation Name="SynchronizeExternalAttributeData" Action="http://tempuri.org/IExternalMappingService/SynchronizeExternalAttributeData" /&gt;
&lt;Operation Name="ModifyAttribute" Action="http://tempuri.org/IExternalMappingService/ModifyAttribute" /&gt;
&lt;Operation Name="DeleteAttribute" Action="http://tempuri.org/IExternalMappingService/DeleteAttribute" /&gt;
&lt;Operation Name="LogOff" Action="http://tempuri.org/IExternalMappingService/LogOff" /&gt;
&lt;/BtsActionMapping&gt;' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.</s:Text></s:Reason></s:Fault>

Hi,
The API Logon function doesn't return a session key. I have a port that was generated by the SVC WS.<o:p></o:p>
All I need to do is preform the logging operation and then synchronize all the data I received in a previous orchestration. 
How do I do it?
p.s the logon operation returns only a status code regarding it's successes or failure
