How do I set up Payflow Pro with PayPal Sandbox?
1.Log in to PayPal Manager.
3.From the main navigation select Service Settings | Setup.
4.The third heading from the top titled PayPal Express Checkout you'll see PayPal Sandbox email address. Enter your PayPal Sandbox Seller email into this field, scroll to the bottom of the page and click on Save.
Your Payflow Manager has now been synced with your PayPal Sandbox account and is ready to begin accepting Test/Sandbox transactions.
NOTE: If you do not see the PayPal Express Checkout section on the Set Up page,
