Where to get Java packages for Google Pay services?

Question

I need to implement Google Pay Passes loyalty card as described in this tutorial, but I am unable to implement it, because I am missing some com.google.android.gms.pay which are not imported as default in Android Studio.

Where to get those packages?

import com.google.android.gms.pay.Pay;
import com.google.android.gms.pay.PayApiAvailabilityStatus;
import com.google.android.gms.pay.PayClient;

I was not able to found them.
