AS per the explanation:
"You can create three payload types in SQL Server 2012: TCP, Service Broker, and Database Mirroring endpoints. SOAP endpoints were removed in SQL Server 2012."
When I refer to this link:
http://msdn.microsoft.com/en-in/library/ms162560.aspx
I found that SOAP is still in list of payload types.
