Get customerPayments API endpoint doesn't return any data

Good Afternoon,

The endpoint Get customerPayments doesn’t seem to return any data:

There is mention of adding the API v2.0 must append $schemaversion=2.0 to the request URL but that makes no odds it seems.
I definitely have made payments in the Cronus company and can pick up the paid invoices ok, just can’t get the payments themselves.


If you want to get the payments for customers how do you go about it? I did see a thread from a year or so ago complaining about getting part paid balances and the customerPayments endpoint not working?
