I am integrating our third party app with a clients NAV 2015 on-site server.
I need to add the ability to get a list of payments that have been entered into NAV for a specific sales invoice but I can't find documentation on how to do this.
I'm assuming I have to query either the General or Customer ledger but I'm completely new to working on NAV API's and I don't know how the data is related. The current implementation I am updating is using SOAP queries if that helps.
