I have only just started building an invoice data extraction app - currently using the 'conventional' method of reading email, download attachment(s), process docs blah blah.
However, some suppliers have 'jumped the gun' on me and are now sending an email notice with a QR code in it that links back to the invoice.
So my questions are :
1. How do I read the QR code that is in the invoice ?
2. Use the link to access the invoice ?
3. CHECK that the invoice is valid before downloading ?
I presume that different suppliers will have different methods to display the invoice? ie: some might open the (PDF?) invoice in a browser tab (expecting that I will save the document from there) and other might just have a link to down load the document.
On a side note: I am questioning the wisdom of 'sending' invoices this way?
I think it would be better to give creditors an API to connect with - but that is another discussion.
