I do hope that I’m missing the blindingly-obvious but I have double-checked before posting.
On the web-view, I can create (and save) an invoice and supply an “Invoice Number”
e.g. myself-quickfile-co-uk/sales/create?invoiceID=123456
It seems that the API even lets me search for it ( Invoice_Search API Schema ) , listing “InvoiceNumber” as a field
But, I can’t create it – It doesn’t seem to exist as a field on Invoice_Create API Schema , and I’ve even tried supplying anyway (to see if it was just missed from the documentation)
Could somebody please tell me how to supply “InvoiceNumber” via the API .?
Many thanks.
