Genesys Interaction with Salesforce using Wsdl

Hello,
I’m trying to connect salesforce to Genesys using a WSDL webservicecapturpoint.
i already tested the webservice in genesys side with SoapUi and it works. In the Salesforce side i created an apex class from WSDL and i’m supposed to create a trigger to call the webservice so i can send the interaction to genesys.
any ideas or samples ?
