Wix Stripe Integration: How We Upgraded to a Custom Stripe API Checkout Using Velo

When your checkout is so smooth, even your finger tips leave a 5-star review.

If you run your business on Wix and want more control over your payment experience, you’ve probably run into the limits of Wix’s built-in checkout tools. While Wix offers simple payment solutions through tools like Wix eCommerce, Wix Events, or Wix Payments, these systems often fall short when you want more flexibility.

That’s where a Wix Stripe integration using custom code (via Velo by Wix) can make a huge difference.

At VeloLogicStudio, we help small business owners implement powerful features using custom code on Wix. In this post, I’ll share how I upgraded my own business, The Story of Ramen, to use a modern, secure, and flexible Stripe API integration on Wix—and why it might be the right move for your business too.

Why We Replaced Our Old Stripe Integration on Wix

For years, we had been accepting online payments using Stripe’s older setup (also known as Create Charge API). It worked, but it was based on a now-outdated method that Stripe no longer recommends. This old integration lacked key features such as:

• Higher decline rates, leading to customer frustration and lost sales.

• 3D Secure authentication, which protects customers against fraud

• Support for modern payment methods like Afterpay, Affirm, and Apple Pay

• Better mobile checkout experiences that today’s customers expect

  
  

Recently, I upgraded to a more modern Stripe checkout setup using the Stripe Payment Element, which brings together multiple payment methods into one secure and streamlined form.

What Is the Stripe Payment Element and Why Does It Matter?

The Stripe Payment Element is a pre-built checkout form that supports:

• Credit and debit cards

• Digital wallets (Apple Pay, Google Pay)

• Buy now, pay later options (Affirm, Afterpay)

• Bank transfers and more

It also automatically handles security steps like 3D Secure authentication and keeps you compliant with modern standards—without you needing to manage those details manually.

This upgrade was critical for us to stay current and offer more payment options to our customers.

Wix Stripe API Integration Isn’t Plug-and-Play

While Stripe has excellent documentation for integrating its Payment Element on traditional websites, Wix’s structure presents some unique challenges:

• Wix doesn’t give developers direct access to the webpage’s underlying structure (known as the DOM), which Stripe’s tools rely on.

• Stripe’s checkout form needs to be embedded in a very specific way that Wix doesn’t natively support.

  
  

So to make the Wix Stripe API integration work, we had to take a hybrid approach.

Our Custom Stripe Integration for Wix: A Simple Explanation

Here’s how we built a working solution using Velo (Wix’s developer platform):

1. Backend Velo Code: This is the secure “server-side” logic that creates payment sessions, talks to Stripe, and handles errors.

   
   

2. Frontend Velo Code: This handles the user experience on the page—what happens when a customer clicks “Pay Now,” for example.

   
   

3. HTML Component Workaround: Because we can’t embed Stripe’s code directly into Wix, we used a special HTML iframe on the page to load the Stripe payment form safely and securely.

We Also Integrated Stripe with Our POS Terminal (WisePOS E)

At The Story of Ramen, we take both online and in-person payments. We wanted a unified system, so we also connected Stripe’s WisePOS E terminal to our Wix setup.

This allows us to accept tap, chip, and swipe payments in-person and have everything flow through the same Stripe dashboard—making accounting and reporting much easier.

Why Not Just Use Wix’s Built-In Payments?

Wix offers some great tools out of the box:

• Wix eCommerce for simple stores

• Wix Events for selling tickets

• Wix Payments for basic online transactions

If those tools meet your needs, great. But many growing businesses quickly hit limits when they want to:

• Offer multiple payment methods

• Use a branded, seamless checkout

• Add tips or upsell items

• Handle recurring billing or subscriptions

• Sync online and offline payments into one system

For all of that, a custom Stripe API integration on Wix is often the only real solution.

The Payoff: Why We Recommend Custom Stripe Integration on Wix

Upgrading to a fully customized Wix Stripe checkout gave us:

• A modern and secure payment experience

• Support for alternative payment methods

• A single system for both online and in-person sales

• Complete control over the customer experience

• Better conversion rates at checkout

We didn’t just “follow the instructions”—we designed a system that fits our brand and our customers.
