This guide covers building custom integrations for supplier operations including inventory feeds, order management, and shipment tracking. ## Prerequisites - Wayfair Supplier Partner account with API access - Familiarity with RESTful APIs, EDI, and JSON/XML data formats - Tools: Postman, Wayfair Partner Home Documentation ## Step 1: Authentication Wayfair uses **OAuth 2.0** for API authentication. Obtain client credentials through the Wayfair Partner portal. ## Step 2: Endpoint Discovery and Data Mapping **Common API Resources:** Inventory Feeds, Purchase Orders, Advance Ship Notices (ASN), Invoices, Returns. Map Wayfair SKUs and warehouse codes to your internal systems. ## Step 3: Building Integration Flows - **Inbound (from Wayfair):** Receive purchase orders, return authorizations - **Outbound (to Wayfair):** Submit inventory feeds, ASNs, invoices, tracking updates ## Step 4: Error Handling and Rate Limiting Handle feed validation errors and EDI compliance requirements. Implement retry logic for API failures. ## Step 5: Security Best Practices - Store OAuth credentials securely - Use HTTPS for all communications - Validate data integrity for inventory feeds - Monitor for compliance issues ## Step 6: Testing and Validation - Test with Wayfair sandbox environment - Validate inventory feed acceptance - Verify order-to-ship workflow compliance ## Step 7: Deployment and Monitoring - Monitor feed acceptance rates - Alert on order processing failures - Track supplier scorecard metrics ## When to Use a Managed Platform For suppliers managing Wayfair alongside other marketplace channels, a managed integration platform like APIWORX provides unified supplier operations orchestration. ### See the APIWORX platform in action Tell us about your systems and we'll build a tailored automation plan within 24 hours.
