Odata API for Successfactor

Hello Gurus,

I need to use Odata in SFSF adpater to call API on Successfactor.

I have gone through Hands-On – Testing Integration with SuccessFactors OData API link. My doubt was how do we create the request format that is sent in header in the step 4 .Is it possible using the communication channels in PI or any other way around.

Please suggest.

Thanks,

Rama.
