Siebel Loyalty engine interface

I would like to be able to use the Siebel Loylaty engine to send Real Time transactions from a POS application.
Scenario includes to be able to get the total points of the customer.
and send a new transaction that generate more points.
Now I am new in this technology. How can I communicate with the Loyalty Real time engine?
Any web services that are available to communicate with the engine or other interface?
I would need a document that describe well the Loyalty engine interfaces.
Thank you.


I was more looking at web services but yes the are 13 Siebel loyalty task flows described in the section A. What I have been looking at is to expose the LOY Processing Engine as a web service. I was able to do this from Siebel tools.
