Supported PayPal providers
Because of PayPal's global availability, it is one of the most commonly used payment providers on the Shopify platform. Shopify supports the following PayPal payment integrations:
- PayPal Express
- PayPal Payflow Pro
We strongly suggest using PayPal Express instead of PayPal Standard. PayPal Standard is deprecated and support for it will be removed from Shopify eventually. PayPal Express is more reliable because PayPal doesn't have to send IPNs (payment notifications) to Shopify. IPNs can be lost, which can prevent orders from being marked as paid on the Shopify side.
Detailed order summary
PayPal Express supports a detailed order summary with descriptions for all line items.
Automated order cancellations
When you cancel an order in Shopify, the amount will be automatically refunded to the customer without requiring you to visit your PayPal account.
You can start accepting payments right away without having a PayPal account. You can sign up later after you've already received payments from your customers.
One-click checkout button
PayPal Express adds a one-click checkout button to the cart or checkout to let customers log in to their PayPal account to pay without entering any address information.
