Has anyone tried to use the Soap Call using offer engine.We tried to use the below document, but could not retrieve the offer.Integration via SOAP (server side)​ Can you help us with any supporting document or sample code for this API call would be helpful ?Thanks in advance !

Hi Everyone,While making API calls we create a session token for every 24hrs.Is these a way to make a API call by without generating a token everyday or the session token validity period can be increased to more that 24 hrs then what would be the maximum limit.Thanks in advance !RegardsSomesh
