I am providing connectivity with a accounting s/w , so I am calling one event "sales_order_invoice_pay"
but I need to update the invoice no. by the invoice no. provided by accounting s/w. So I need a event in which I can get the information of invoice just after invoice generation.
thanks
it depends on your magento version also because earlier magento has
sales_order_invoice_save_after
But you have to check your version and availability of the event.
