Hi all,
I want to write a program to fetch invoice via Acumatica openAPI and send to clients. My problem is after send invoice to clients, I want to add a note to the invoice in the Acumatica. I checked openAPI and can not find any endpoints related to modify invoice. I only found a /Invoice/{actionName} endpoint maybe can do that. Also I can’t find any action like add a note. Does anyone have any idea on this?
