When testing your Payflow integration using the PayPal Sandbox, you must have a PayPal Sandbox seller account linked to Payflow Manager before switching your shopping cart/payment module to a Sandbox or Test mode. Prior to following the steps below, ensure you have created Sandbox buyer and seller accounts.
Here's how:
- Log in to your PayPal Manager account.
- Select Service Settings > Set Up.
- Under PayPal Express Checkout you'll see PayPal Sandbox email address. Enter your PayPal Sandbox seller email address, scroll to the bottom of the page, and click Save.
Note: If you don't see the PayPal Express Checkout section on the Set Up page, contact Merchant Technical Support and ask that Express Checkout be added to your Payflow account for testing purposes. Provide your Sandbox email address and your Payflow merchant login information when creating the ticket.
