This guide covers building custom integrations for data-driven demand planning. ## Prerequisites - Sage Demand Planner with API or data export access - Familiarity with RESTful APIs, CSV/XML data formats, and database connectivity - Tools: Postman, Sage Documentation, ETL tools ## Step 1: Authentication Sage Demand Planner typically uses **API Key** or **database-level** authentication depending on the integration method. ## Step 2: Endpoint Discovery and Data Mapping **Common Data Resources:** Historical Sales, Forecasts, Inventory Levels, Product Hierarchies, Planning Parameters. Map sales history and product hierarchies from ERP to Demand Planner inputs. ## Step 3: Building Integration Flows - **Inbound (to Demand Planner):** Load historical sales data, product catalogs, inventory snapshots - **Outbound (from Demand Planner):** Retrieve demand forecasts, recommended order quantities, planning alerts ## Step 4: Error Handling and Data Validation Validate data completeness before loading. Handle missing historical periods and product hierarchy mismatches. ## Step 5: Security Best Practices - Encrypt data files in transit - Use secure database connections - Implement access controls for planning data - Audit data load operations ## Step 6: Testing and Validation - Test with representative historical data sets - Validate forecast accuracy against actuals - Verify planning parameter configurations ## Step 7: Deployment and Monitoring - Monitor data load success rates - Alert on forecast generation failures - Track planning accuracy metrics ## When to Use a Managed Platform For businesses integrating demand planning with ERP, eCommerce, and supply chain systems, a managed integration platform like APIWORX provides automated data orchestration for planning workflows. ### See the APIWORX platform in action Tell us about your systems and we'll build a tailored automation plan within 24 hours.
