PayPal Payment Link Generator
Feel free to use this PayPal Payment Link Generator. It will generate a HyperLink and QR Code with the details you proved.
I am using it extensively to create one-time payment links. I am using both the HyperLink and QR-code image on my PDF invoices to make it more convenient for clients to perform quick direct payments without the confusion.
What it does is, it sends the client over to PayPal. The client only needs to log in and confirm the payment. All the crucial details like your account, the payment description and amount in the correct currency are loaded for them.
