Square Webflow Integration
🌎Square is a platform for payment processing, POS, invoicing, and e-commerce. It empowers businesses to accept payments, manage sales, and streamline operations from one place.
Square integrates with Webflow to add seamless payment acceptance to any Webflow-built site. Using Square's payment APIs or pre-built embeddable components, you can accept credit cards, digital wallets, and ACH payments directly on your Webflow pages — no redirect to a third-party checkout required. This keeps the purchase experience entirely within your branded Webflow environment.
For Webflow e-commerce sites, Square offers a compelling alternative to native Webflow Ecommerce. Square's developer tools include a customizable payment form, a hosted checkout option, and a full API for building custom checkout flows. You embed the Square payment component via a script tag in Webflow, handle the payment token exchange on your backend, and Square processes the transaction — keeping PCI compliance on Square's side.
Beyond payments, Square's broader ecosystem — including invoicing, inventory management, and POS hardware — means Webflow sites can serve as the online storefront for businesses that also sell in person. A customer can browse products on a Webflow site, pay online via Square, and the same inventory system tracks stock across web and physical locations. This unified view of sales is invaluable for omnichannel retailers.
Square FAQs
Common questions about using Square with Webflow.
Square provides a Web Payments SDK that you embed into your Webflow page using a Custom Code element. The SDK renders a secure payment form that tokenizes card details without them ever touching your server. You then send the token to your backend, which calls Square's Payments API to complete the charge. Square's developer docs include copy-paste examples for this exact flow.
Square does not integrate directly with Webflow's native Ecommerce checkout. You have two options: use Square's hosted checkout button for simple product sales on Webflow pages, or build a custom store using Webflow's CMS and Square's APIs. The custom CMS approach gives you full design control and is the recommended path for Webflow agencies wanting a unique checkout experience.
Yes, this is one of Square's strongest use cases. If your client runs a physical store with Square POS and also sells through a Webflow site, Square's unified dashboard shows all transactions in one place. Inventory syncs across channels, customer profiles are shared, and reporting covers both online and in-person sales without manual reconciliation.
Square processes all major credit and debit cards, Apple Pay, Google Pay, and ACH bank transfers. The payment form automatically detects the customer's device and surfaces the relevant wallet options. Square also supports recurring payments and subscription billing if you use their Invoices API or a third-party subscription layer on top of Square.
Yes. Square's Web Payments SDK handles card data collection in a PCI-compliant iframe, and Square's servers handle all sensitive data processing. Your Webflow site and backend never touch raw card numbers, which keeps your PCI scope minimal — typically just an SAQ A self-assessment. Square provides documentation for the compliance steps you need to complete.
