Get customerPayments API endpoint doesn't return any data

Good Afternoon,

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

https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/api/dynamics_customerpayment_get

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.

{{base-dynamics-v2-url}}/companies({{company_id}})/customerPayments

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?

Cheers

Mat
