Supported Payment Gateway for One Click Upsells
CartFlows Pro allows you to offer one‑click upsells and downsells to increase the average order value of your sales funnels. For this functionality to work properly, the payment gateway used during checkout must support the required tokenization or reference transaction features.
Below is the list of payment gateways that are officially supported for CartFlows one‑click upsell and downsell offers.
Supported Payment Gateways
CartFlows Pro supports one‑click upsells with the following gateways:
- Authorize.net
- BACS (Direct Bank Transfer)
- Cash on Delivery (COD)
- Mollie – Credit Card and iDEAL
- WooCommerce PayPal Payments
- Stripe – Credit Card
- Square
These gateways have built‑in compatibility with CartFlows to process additional offers without requiring the customer to re‑enter payment details.
Gateway Compatibility Notice
One‑click upsells require dedicated compatibility with each payment gateway. Because of this, support must be built individually for every gateway.
The CartFlows team continues to add compatibility for more gateways over time as they become available.
If you attempt to use a payment gateway that is not supported, CartFlows will display a notice on the Upsell or Downsell step in the Flow editor.
This notice indicates that the currently selected gateway does not support one‑click upsells.
Frequently Asked Questions
To avoid this, you can either use the supported payment gateways or you can add custom support of your payment gateway in the CartFlows with the help of a freelance developer.
