API to update payment method of an invoice
I have a requirement to create WEBADI for a couple of fields in an invoice:
1) Payment Method
2) In the scheduled payment tab of invoice form there is a DFF - need to update that as well.
Please let me know the API for the first one.
As for the second one, do API's exist for updating DFF segment values? If not then how is it achieved?
