Before saving, consider if you need to use Venmo, Pay Later, or FraudNet. Check the appropriate box as needed. Venmo and Pay Later are supported only when referenceTransactions is disabled OR referenceTransactions and vaultEnabled are both enabled. You cannot choose different payment types for checkout and upsells. For example, if a checkout is done on Venmo then the upsell must also be on Venmo. Rebills are supported on Venmo when referenceTransactions and vaultEnabled are both enabled. Rebills are never supported on Pay Later. |

Step 6: Edit Checkout page and add PayPal button
...
CheckoutChamp knows if the customer paid with a credit card or PayPal on the initial sale and will process with the same paySource payment method on the upsell pages. This means you don’t need to design your upsell pages any differently than they already are. Using your existing “yes” “Yes” button on the upsell pages, a PayPal customer will redirect to PayPal if the PayPal gateway added into CheckoutChamp does not have Reference Transactions enabled.
