DirectInvoiceURL on invoice with QR Code

Hello,

I’d like to have a QR code on a printed copy of any invoice that opens a payment link. I appreciate that printed copies of invoices are not the direction we should be moving in.

I found information for generating a QR Code elsewhere on the Forum, so for example, I can use

img src=“http://api.qrserver.com/v1/create-qr-code/?data=@DirectInvoiceURL@” style=“width:60px;”/

on the Routine Emails. However, placing that code in the Invoice Customisation/Footer Region just generates a QR Code with the non-parsed text “@DirectInvoiceURL@”. Other tokens such as @InvoiceID@ seem to work (as per the original forum request), but not this. Is it possible for it to work in the Invoice Footer?

Many thanks,
Geoff
