# 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.

{% hint style="info" %}
If you are using the CheckoutChamp funnel builder, please see the bottom [of this article](/funnel-builder/creating-and-editing-funnels-pages/funnel-visualizer-and-page-builder/funnel-visualizer/edit-funnel-settings/payments/paypal.md#paypalseamlesscheckout-checkoutchamp-upsellswithoutreferencetransactionsenabled).
{% endhint %}

#### Follow the [PayPal Seamless Checkout (Legacy)](/crm/gateway-setup/gateway-integrations/paypal-commerce-checkout/paypal-commerce-checkout-legacy.md) instructions through Step 6. Instead of continuing with Step 7 on that article, follow the below instructions: <a href="#follow-the-paypal-seamless-checkout-direct-api-instructions-through-step-6.-instead-of-continuing-wi" id="follow-the-paypal-seamless-checkout-direct-api-instructions-through-step-6.-instead-of-continuing-wi"></a>

&#x20;

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)

&#x20;

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.
