This guide outlines a secure, scalable strategy for building custom integrations with eCommerce platforms, ERP systems, and 3PL providers. ## Prerequisites - ShipStation API Key and API Secret - Familiarity with RESTful APIs, Basic Authentication, and JSON data formatting - Tools: Postman, ShipStation API Documentation, SDKs (Python, Node.js) ## Step 1: Authentication ShipStation uses **Basic Authentication** with API Key and Secret. All API calls must be made over HTTPS. ## Step 2: Endpoint Discovery and Data Mapping **Common API Resources:** Orders, Shipments, Carriers, Shipping Labels, Stores. Important considerations include consistent order ID mapping, proper carrier code usage, and accurate package dimension and weight handling for label generation. ## Step 3: Building Integration Workflows - **Inbound (to ShipStation):** Submit new orders, update customer information - **Outbound (from ShipStation):** Retrieve shipping labels, order statuses, and tracking numbers ## Step 4: Error Handling and Rate Limiting ShipStation enforces API rate limits (typically 40 requests per minute). Implement exponential backoff and retry logic for 429 responses. ## Step 5: Security Best Practices - Never expose API credentials in client-side code - Use HTTPS exclusively - Rotate API keys periodically - Implement IP whitelisting where possible ## Step 6: Testing and Validation - Use ShipStation sandbox or test stores - Validate label generation with dummy shipments - Test webhook callbacks for order status updates ## Step 7: Deployment and Monitoring - Monitor API usage against rate limits - Set up alerting for failed shipment creations - Log all API interactions for audit trails ## When to Use a Managed Platform For complex multi-channel fulfillment workflows requiring orchestration across multiple carriers and warehouses, a managed integration platform like APIWORX can significantly reduce development and maintenance overhead. ### See the APIWORX platform in action Tell us about your systems and we'll build a tailored automation plan within 24 hours.
