How can i get the wsdl for successfactors compound api to map in sap pi

Hi Experts,

I am doing the Integration between the successfactors and third party systems. So at this point i am trying to fetch the data from the successfactors to pi. As of my understanding the pre-requisites are

1. Need to maintain the service pack level SP09 for 7.31

2. Nedd to Install the Pi Connectivity addon for the SuccessFactors.

Here my query is like how can we get the wsdl file from the successfactors to map the data for a particular API Of Successfactors for Example Compound Employee API.Please Suggest me.

Regards

Giridhar.
