How do I create a "One Click Upsell"?

One Click Upsells or Post Purchase upsells have the following flow:

Customer is on checkout page, enters  card details and purchases the offer.

Redirected to upsell page where they can click a button and that charge will  be added to their order.

Redirect to thank you page.

Inside our platform, we use forms to capture payments, and we tokenize card data inside the platform. This means we can trigger payments for any user at any time based off their input.

To create a "One Click Upsell", you first need to create a purchase form, and have the redirect setup in the form to redirect the user to the One click upsell page.

Next, you want to create another form, which consists purely of a button, nothing else.

That button will be your one-click-upsell button.

Put that on the "One Click Upsell" page in the site builder and then build a flow using that "Form" as the trigger.

The only element you'll need is "Order Product/Subscription" and you can choose which product they'll be buying when they click the button on the page.
