Amazon Seller Central

How to integrate Amazon Seller Central with Webflow

Connect Amazon Seller Central with Webflow through automation platforms (Zapier, Make) for basic order sync, or custom API development for inventory management, product catalogs, and customer data access.

Use automation platforms

Zapier and Make provide pre-built connectors for basic Amazon-to-Webflow workflows without code.

Critical limitation: Zapier's Amazon Seller Central integration has significant restrictions:

• Only the "New Order" trigger is available (no inventory or product sync triggers)
• No customer data access — Amazon's API blocks names, addresses, emails, and phone numbers through third-party platforms
• Only basic order fields available: Order ID, Status, Total, Purchase Date

This means order tracking dashboards with customer information are impossible via Zapier — they require custom API development.

Example Zapier workflow:

1. Trigger: Amazon Seller Central → "New Order"
2. Action: Webflow → "Create Item" in CMS collection
3. Map available fields: OrderId, OrderStatus, OrderTotal, PurchaseDate

Requirements:

• Amazon Professional seller account ($39.99/month)
• Third-party platforms are limited to North American Amazon accounts
• Zapier free plan: 100 tasks/month with 15-minute polling. Professional plan: $19.99/month for 750 tasks.

Build with Amazon SP-API

Custom API integration enables inventory sync, product catalog management, customer data access, and real-time webhooks — capabilities unavailable through automation platforms.

Authentication (updated October 2023)

Amazon SP-API now uses Login with Amazon (LWA) OAuth 2.0 only. AWS IAM credentials and Signature Version 4 signing are no longer required. Access tokens expire after one hour — implement automated refresh logic.

Webflow authentication

Bearer token authentication with site-specific tokens. Tokens expire after 365 consecutive days of inactivity.

Key capabilities:

• Product catalog sync: GET /catalog/2022-04-01/items/{asin} for product data → POST to Webflow CMS API
• Inventory sync: GET /fba/inventory/v1/summaries for stock levels, or subscribe to FBA_INVENTORY_AVAILABILITY webhook notifications
• Order processing: GET /orders/v0/orders with temporal filters

Rate limits:

• Amazon Orders API: 0.0167 requests/second (one per minute sustained) — most restrictive
• Amazon Catalog Items API: 5 requests/second
• Webflow: 60-120 requests/minute depending on plan
• Webflow publish endpoint: 1 successful publish per minute

Webhook notifications

Subscribe to ORDER_CHANGE, FBA_INVENTORY_AVAILABILITY, and LISTINGS_ITEM_STATUS_CHANGE via AWS SQS or EventBridge for real-time sync instead of polling.

What you can build

Integrate Amazon Seller Central with Webflow for multi-channel retail operations.

• Basic order tracking: Sync new Amazon orders to Webflow CMS collections displaying Order ID, status, total, and date. Note: Customer names and addresses are not available through automation platforms.
• Full order dashboards: Build complete order tracking with customer information, shipping addresses, and line items. Requires custom SP-API development — not possible with Zapier or Make.
• Inventory-synced product catalogs: Maintain synchronized product data and stock levels across Amazon and Webflow. Automation platforms lack inventory and product sync triggers.
• Amazon MCF-powered stores: Create branded Webflow e-commerce experiences that fulfill through Amazon's Multi-Channel Fulfillment network.
