Amount paid in currency for supplierPayment

[Maja Damber]

How can I find the amount paid to a supplier in currency? Most of the time an invoice is paid with the total amount so then I can find this out but i it is partly paid this won't be possible. I want to find out the payments effect on the accounts payable balance. 
There is a field called "balance" on the paymentLines. What will this show if the invoice is partly paid? Will this be the remaining balance in currency after the payment?

Hi again.

It was a long time since I asked this question. But I never really got a solution that I was completely satisfied with. The balance field on the Supplier Invoice you are mentioning, I think will be hard to use for this purpose. 
Why is paid amount in currency not exposed in the API endpoint?

Or can someone explain how the balance field on the Supplier Payment itself works? If an invoice is partly paid, will this field show the balance left on the invoice at the time of this payment? Then this is more like something I can use.

Hi, 

 "balance": 0,
  "balanceInCurrency": 0,

 fields can be checked on the Supplier Invoice for the remaining unpaid amount of the invoice. 

There is also a tab that is called "Applications" in the Supplier Invoice where we can see the applied payments and its details but unfortunately this is not exposed via the API atm.
