Perfect. Hi @Roy L Here's my question. Have you tried using it with the new payment link feature from 2021.2 that lets you put a url in emailed invoices that customers can use to remit payment via credit card? It involves use of payment instruments, which I'm also not familiar with but I'm starting with ‘will PayPal PayFlow even work' before I go too far down the rabbit hole.
If you know, great. If not I'll just try and see where I get stuck.
