Can I integrate a different checkout payment service with Webflow Ecommerce using an API or custom code?

You cannot directly replace Webflow’s built-in checkout/payment system with a different service like Stripe, PayPal (outside of the default options), or custom gateways within Webflow Ecommerce itself. But there are alternative approaches using APIs and custom code.

1. Understand Webflow's Commerce Limitations

• Webflow Ecommerce tightly integrates with Stripe and PayPal (in supported regions) for payments.
• The native checkout process cannot be overridden or deeply customized—you can't inject a different service into Webflow's default checkout.
• Webflow does not expose its cart or checkout APIs publicly for advanced custom gateway modifications.

2. Use Webflow Forms + Custom Checkout Flow

• Instead of using Webflow's Ecommerce platform, you can create a custom store using CMS collections (for products) and Webflow forms for orders.
• Use tools like:
• Snipcart or Foxy.io for embedding fully customizable cart + checkout experiences with broader payment gateway support.
• Make (Integromat), Zapier, or custom APIs to route form data to external systems (e.g., custom order fulfillment + Stripe/PayPal/Braintree).
• You'll embed third-party scripts and manage inventory/order logic outside of Webflow.

3. Implement a Headless Approach

• Use Webflow as a front-end CMS, pulling product data and managing page layouts.
• Handle checkout and payment via an entirely external application or headless commerce system (e.g., Shopify Headless, Stripe Checkout, or custom React app).
• You’ll redirect users from Webflow product pages to your own external checkout built with your preferred payment provider.

4. Consider Workarounds with Stripe Checkout

• Build a custom Stripe-hosted checkout (using the Stripe API) and use Webflow buttons with custom JavaScript to call that checkout.
• Store product data in Webflow CMS; fetch it via API and dynamically populate Stripe Checkout sessions.
• Webflow won’t manage orders or inventory—this must be handled outside.

Summary

You cannot directly integrate a custom payment service inside Webflow's native checkout, but you can create a custom storefront with CMS, forms, external tools like Snipcart or Foxy.io, or redirect users to custom Stripe Checkout pages using APIs and JavaScript. This approach gives you full payment flexibility but removes Webflow Ecommerce’s native order management features.
