How to integrate BigCommerce with Webflow

Integrating BigCommerce with Webflow separates visual presentation from commerce functionality while maintaining consistent customer experiences. This setup works well when you need custom product displays with live inventory data, branded shopping experiences, or product landing pages that sync with catalog information.

You can connect the platforms through Zapier for basic data synchronization or build custom integrations using the BigCommerce and Webflow APIs. Review the BigCommerce Storefront API documentation for headless commerce implementation guidance and the

for content management capabilities.

Use Zapier for basic data synchronization

Zapier's BigCommerce-Webflow integration connects both platforms through trigger-action workflows. When events occur in BigCommerce such as new orders, product updates, or customer registrations, Zapier executes corresponding actions in Webflow like creating CMS items or updating collections. The platform supports standard data types including text, numbers, and dates without transformation.

Some common automation workflows include:

• Sync product catalogs from BigCommerce to Webflow CMS collections with Zapier's product triggers
• Create CMS items in Webflow when new products are added in BigCommerce
• Update inventory data in Webflow collections when stock levels change
• Capture form submissions from Webflow and create customers in BigCommerce

This approach requires adding filters to exclude incomplete or abandoned orders, as Zapier triggers on all order events by default. BigCommerce orders may take up to 30 minutes to appear in connected systems, and typically only orders with "Captured" payment status trigger automation workflows. Zapier cannot map BigCommerce custom fields, which limits data richness in synchronized content.

Build with Webflow and BigCommerce APIs

API integration provides complete control over data synchronization, authentication flows, and custom functionality between BigCommerce and Webflow. This approach supports custom checkout implementations and sophisticated user experiences that automation platforms cannot deliver. You'll need server-side code to handle API requests, manage authentication tokens, and process webhook events.

The BigCommerce Storefront API and Webflow CMS API provide the foundation for custom integrations. BigCommerce handles product data, inventory management, cart operations, and payment processing while Webflow manages content presentation, page layouts, and visual design. Your integration code coordinates data between both platforms through their respective REST APIs.

Synchronize product catalogs with webhooks

Webhook-based synchronization keeps Webflow CMS collections updated when product data changes in BigCommerce. This pattern removes manual data updates and keeps content accurate across both platforms. Implement webhook listeners that receive BigCommerce events and update corresponding Webflow CMS items through API calls.

Configure BigCommerce webhooks for product, category, and inventory events that trigger when changes occur. The store/product/* webhook fires for all product events including creation, updates, and deletion. The store/sku/inventory/* webhook tracks inventory changes for stock updates. Each webhook delivers a minimal JSON payload containing the resource type and ID, requiring additional API calls to fetch complete product details.

Key webhook events for catalog synchronization include:

• Monitor product changes with store/product/* events that fire on creation, updates, and deletion
• Track inventory updates through store/sku/inventory/* webhooks for stock synchronization
• Handle category modifications with store/category/* events to maintain content organization
• Manage URL changes using store/routes/* webhooks that affect SEO and navigation

Webhook payloads include a hash field for implementing idempotency, preventing duplicate processing when events fire multiple times. The created_at Unix timestamp enables chronological event ordering for proper synchronization. BigCommerce requires HTTPS endpoints on port 443 and implements automatic retry with exponential backoff for failed deliveries.

Use the Webflow CMS API to create and update collection items when webhooks fire. As of July 2025, the API requires a two-step process: first update items through staged endpoints, then publish them separately using the dedicated "Publish Item" endpoint.

This creates rate limiting constraints where publishing is limited to approximately one item per minute, despite the advertised 120 requests per minute for general API operations. This limitation prevents true real-time inventory synchronization and requires batching updates or accepting 1-2 minute delays.

Implement customer authentication flows

Customer authentication synchronizes user sessions between Webflow's content pages and BigCommerce's checkout system. This pattern allows direct transitions from marketing content to purchase flows without requiring customers to re-authenticate. The BigCommerce Customer Login API generates JWT tokens for authenticating customers, but strict security constraints require careful implementation.

JWT tokens remain valid for only 30 seconds and invalidate after single use to prevent replay attacks. Generate tokens on demand when customers navigate from Webflow to BigCommerce checkout. The token payload must include a channel_id parameter for headless storefronts to prevent CORS errors. Clock synchronization between your server and BigCommerce is required, or validation against the Get System Timestamp endpoint prevents timestamp skew errors.

Webflow provides workspace-level SSO for team members on Enterprise accounts through Single Sign-On (SSO) Login, but no customer authentication capabilities exist for site visitors. Implement separate authentication mechanisms for public-facing user login that coordinate with BigCommerce customer accounts through custom code and third-party services.

Manage PCI compliance requirements

Custom payment integrations elevate PCI compliance requirements beyond standard implementations. BigCommerce maintains PCI DSS Level 1 compliance as a service provider, but third-party applications processing, storing, or transmitting payment card data must obtain independent certification and submit self-assessment questionnaires (SAQs).

The BigCommerce PCI compliance documentation specifies that custom headless storefronts must maintain PCI DSS certification via a Qualified Security Assessor (QSA) when handling cardholder data. Never store sensitive authentication data including CVV codes, full magnetic stripe data, or PINs after authorization completes.

Webflow qualifies for SAQ A compliance by outsourcing cardholder data functions. Custom payment processing integrations may elevate compliance requirements beyond this level. Design integration architectures that minimize direct handling of payment card data, using BigCommerce's hosted checkout or embedded payment widgets when possible.

What you can build

Integrating BigCommerce with Webflow enables custom e-commerce experiences that separate visual presentation from commerce functionality while maintaining consistent customer experiences across both platforms.

• Custom product catalogs with inventory synchronization: Build dynamic product pages in Webflow that display inventory data from BigCommerce, updating stock levels and pricing without manual content updates (updates occur every 1-2 minutes due to API publishing constraints)
• Headless storefronts with branded checkout: Create custom shopping experiences where Webflow handles all content pages and product displays while BigCommerce manages cart operations and secure payment processing (requires separate server infrastructure for integration code)
• Product landing pages synced with catalog data: Design product landing pages in Webflow that sync with BigCommerce catalog information, enabling rapid campaign deployment while maintaining accurate product details and inventory availability
