What does postback mean within the e-invoicing product?
Payment Center - e-invoicing
Posting paid invoices back to my product using e-invoicing
Paya Payment Center will post customer payments to the connected account you chose when you set up the connection. To change this account, go to Open Invoices > Invoice Settings.
Additionally, Paya Payment Center will post invoice status updates. For example, if a customer pays the full balance of their invoice from a reminder email, Paya Payment Center will update it as Paid and also update the invoice status in your connected product.
