How it works
For example, you've sent an invoice to a client. There is a special button to pay using PayPal.
The client clicks this button and gets to the PayPal Checkout page.
Another example: a client selects PayPal as a payment method when shopping at your online store.
After proceeding to the online store checkout page, he/she will be redirected to the PayPal Checkout page.
