Frequently Asked Questions about the Working of PayPal/Stripe!

Does the user have to activate auto-redirect on PayPal account after payment so that it should be redirected to the upsell?

No, not compulsory.

Does the user have to add the identity token to the WooCommerce’s PayPal settings?

Yes, if the IPN email notification is enabled.

What are Reference Transactions?

Reference Transactions allow you to set a Billing Agreement between a merchant and customer at the time of checkout. This Billing Agreement with the customer allows you to charge the customer at a later time.

Why Reference Transactions?

To run true “One Click” Upsell, CartFlows uses Reference Transactions to enable One Click Upsells after checkout. It utilizes a Billing agreement between you and your customer and charges the customer if the offer is accepted.

Can I run upsells if the reference transaction is off in my PayPal account?

Yes! You can run up-sells even if reference transactions are off. The only change in flow that it would need, one additional confirmation from PayPal to process the payment. So it’s two-click up-sells. To understand the difference in detail

2. Log into your PayPal account.
3. Go to the Email Contact Form.
