How do I accept credit cards using guest checkout with PayPal Express Checkout?

Guest checkout gives payers the option to complete a purchase using a credit or debit card without having a PayPal account. To use guest checkout, you must: 

• Confirm your email address.
• Verify your PayPal account.

Here's how to enable guest checkout: 

1. Log in to your account. 
2. Select Account Settings > Website payments. 
3. Next to Website preferences, select Update. 
4. Under PayPal account optional, select On. 

Note: With an Express Checkout custom-coded solution, there is an additional step: 

• Set SOLUTIONTYPE to Sole in your initial SetExpressCheckout API call
• For SOLUTIONTYPE=Sole to work, you must have PayPal account optional set to On within the PayPal account settings
• Many third-party carts provide an Enable Guest Checkout option in the administrative view of their checkout module
