Apple Pay Integration using Cybersource - ios

Question

I am Integrating Apple Pay Integration using cyberSource in my Application .
what i have done so for .
1- I have created merchant ID
2- I have created test account on http://www.cybersource.com/
3- I have downloaded cybersource SDK for iOS.
4- I have managed to run Demo Application downloaded with SDK.
5- When i run demo App i am getting this error.
"Transaction Details .Accepted: No .Auth Amount: (null) Error: Unknown error"
I have provided my merchant account correctly . There are other fields as well which i am not sure how to get those values

From where i can get all these values . it will be highly appreciated if some one in list all steps involved in Apple pay integration through CyberSource.
Also Please do not refer me to apple developer as i have read out details about Apple Pay on Apple Developer.
