How to integrate Shippo with Webflow

Connecting Shippo to Webflow transforms manual shipping workflows into automated fulfillment processes.

To integrate Shippo with Webflow, use Webflow’s Custom Embed feature or build a custom solution using Webflow’s and Shippo’s APIs.

Use Custom Embed elements

Embed Shippo’s Shipping Elements widget on your own checkout pages.

Note: Webflow’s native cart and checkout experience can’t host custom scripts. To use Shippo, build a custom checkout page (static or CMS) with Embed, or host it externally, and push orders to Webflow via Webflow’s Ecommerce API after label purchase.

To implement this, add Shippo’s client-side script to your custom page with an Embed element.

Use server-side infrastructure (e.g., AWS Lambda, Netlify, etc.) to generate a secure, short-lived JWT (required for Shippo authentication).

Then, initialize and render the component where you collect shipping details.

Here’s an example of a code snippet you can use to embed and initialize Shippo’s widget:

This method enables:

• Fully branded shipping experience
• Real-time carrier rate display
• Inline label purchasing
• Custom packaging rules via widget options

Build with Webflow and Shippo APIs

Direct API integration unlocks advanced shipping workflows beyond the native app's capabilities. This approach suits businesses with complex fulfillment requirements, multi-location inventory, or custom automation needs.

The Webflow and Shippo APIs enable programmatic control over shipping operations, from dynamic rate calculations to automated batch processing. You'll need server-side infrastructure (AWS Lambda, Netlify Functions) to securely handle API authentication and data transformation between platforms.

Core capabilities include:

• Batch label generation for high-volume order processing
• Multi-piece shipments with complex packaging logic
• Custom tracking pages with branded delivery experiences
• Returns automation including prepaid label generation

Automate high-volume fulfillment

Process hundreds of orders simultaneously using Shippo's batch endpoints:

1. Export orders from Webflow using GET /sites/{site_id}/orders to retrieve order data
2. Create batch shipments via Shippo's POST /batches/ endpoint with up to 10,000 orders
3. Purchase labels in bulk through POST /batches/{batch_id}/purchase
4. Update Webflow orders using POST /sites/{site_id}/orders/{order_id}/fulfill

The batch processing documentation provides detailed parameters for validation rules and error handling.

Build dynamic shipping calculators

Display real-time shipping rates during checkout:

1. Capture order details from Webflow's checkout form via webhooks
2. Request rates from Shippo using POST /shipments/ with customer address and package details
3. Display options to customers through custom UI components
4. Process selected rate via POST /transactions/ to generate labels

Implement address validation using Shippo's POST /addresses/ endpoint with validate=true to reduce delivery failures. The address validation guide explains confidence scoring and standardization rules.

Create automated returns workflows

Streamline reverse logistics with programmatic return label generation:

1. Monitor return requests through Webflow form submissions or customer portal
2. Generate return labels using POST /shipments/ with is_return=true parameter
3. Email labels to customers with tracking enabled for visibility
4. Update order status in Webflow CMS when items are received

The returns documentation covers scan-based labels that only incur charges upon usage.

What you can build

Integrating Shippo with Webflow creates opportunities for sophisticated e-commerce operations and enhanced customer experiences.

• High-volume e-commerce stores: Process 500+ daily orders using batch label printing and manifest generation, reducing fulfillment time by 70% while accessing volume-based carrier discounts
• International D2C brands: Expand globally with automated customs documentation, multi-currency support, and region-optimized carrier selection for 30+ countries
• Subscription box services: Automate recurring shipments with scheduled label generation, weight-based routing rules, and integrated tracking for predictable delivery experiences‍
• Print-on-demand businesses: Sync variable-weight products from production partners, generate labels automatically, and provide white-label tracking pages, maintaining brand consistency
