Here's the 2 task in detail:
#1 - Need an email to be sent after an order status has been marked paid. (currently using the notif by eshopadmin app for this function), so, it's just how to make it work.
*Content to this email, is exactly what is loaded in the order confirmation email notification. (includes acknowledgment of payment, attached pdf link to download the confirmation receipt/invoice).
#2 include a link to directly download the confirmation receipt template when customer go to their "my account" section. 1 invoice = 1 order line. Add the link "Download Confirmation Receipt" beside the fulfillment status.
Same as previous, pls provide the full documentation as to what exact code adjustments have been made and where.
