Admins are now able to set PayPal as a means of accepting payments from customers.
Simply login to your PayPal developer dashboard and get your PayPal Client ID and Client Secret keys. If you don't have them yet, simply create a new app there.
You will then be able to select either one-time payments or subscription plans while assigning a payment or plan.
Please note that when using PayPal you cannot charge one-time payments and subscription plans at the same time.
