Update payment date via API
Unfortunately there’s not an option to update an invoice payment. So you’d instead need to get it and store it to a local object using the following call:
https://www.kashflow.com/developers/soap-api/GetInvoicePayment/
Then delete it from the server using the following call:
https://www.kashflow.com/developers/soap-api/DeleteInvoicePayment/
Then create it as a new payment (based on the object you earlier retrieved, but with the correct date)
