PayPal Seamless Checkout - 2-Click Upsells (without Reference Transactions)

This article provides instructions to perform 2-click upsells with PayPal legacy workflow. This is to be used in the scenario that a PayPal rep cannot enable the Reference Transactions option inside of your PayPal account.


If you are using the CheckoutChamp funnel builder, please see the bottom of this article.

Follow the PayPal Seamless Checkout (Legacy) instructions through Step 6. Instead of continuing with Step 7 on that article, follow the below instructions:

Pass the following on Import Upsale API call to process "2-click" upsells through PayPal.

  1. salesUrl = the url of the page in your funnel that Paypal will redirect to on a successful transaction

  2. paySource = PAYPAL

  3. paypalBillerId (optional since it can be derived from the checkout)

The shopper will be redirected to PayPal just like they were redirected when buying main offer.

Once redirected back to the funnel, call Import Upsell again but include the paypalAccept, token, and payerId returned from PayPal on the upsell. This will complete the upsell transaction.
