Extensiv Order Manager (formerly Skubana) is a powerful order and inventory management platform designed for scaling eCommerce businesses. It unifies sales channels, automates order routing, and optimizes inventory across warehouses. This DIY Developer Guide for Extensiv Order Manager provides a clear, actionable approach to building secure, scalable, and efficient custom integrations with ERPs, 3PLs, and shipping platforms.

Prerequisites for Extensiv Order Manager Integrations

• Extensiv Order Manager API access credentials
• API Key and Secret or OAuth setup
• Familiarity with:
  • RESTful APIs
  • OAuth 2.0 Authentication
  • JSON data structures
• Tools: Postman, Extensiv API Documentation, SDKs (Node.js, Python)

Step 1: Authentication for Extensiv Order Manager Integrations

Extensiv Order Manager uses OAuth 2.0 for secure API access.

Authentication Example:

POST https://auth.extensiv.io/oauth/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=YOUR_CLIENT_ID
&client_secret=YOUR_CLIENT_SECRET

Use the returned access_token in the Authorization header for all API requests.

Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

• Orders
• Inventory
• Products
• Warehouses
• Shipments

Process:

• Review Extensiv Order Manager’s API documentation carefully.
• Map ERP or eCommerce platform fields (e.g., SKU, warehouse ID) to Extensiv fields.

Important considerations:

• Consistent SKU and warehouse ID mappings
• Proper handling of order statuses (e.g., pending, fulfilled, cancelled)
• Accurate tax and shipping method field mappings

Step 3: Building Integration Workflows

Integration Patterns:

• Inbound (to Extensiv): Submit products, create orders, update inventory.
• Outbound (from Extensiv): Retrieve order statuses, inventory levels, and shipment updates.

Example: Creating an Order

POST /api/orders
{
  "order_number": "ORDER12345",
  "items": [
    { "sku": "SKU001", "quantity": 3 }
  ],
  "shipping_address": {
    "name": "John Doe",
    "street1": "123 Main St",
    "city": "New York",
    "state": "NY",
    "postal_code": "10001",
    "country": "US"
  }
}

Example: Fetching Inventory Levels

GET /api/inventory/warehouses
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

• Capture HTTP error codes and Extensiv-specific error messages.
• Implement retries for transient errors (5xx) and handle 429 (rate limiting) errors.

Pagination:

• Use page and pageSize parameters for paginated endpoints.

Example:

GET /api/orders?page=2&pageSize=100

Step 5: Testing and Validation

• Test workflows using Postman and Extensiv’s sandbox environment.
• Validate order creation, inventory syncs, and shipment updates.
• Stress test high-volume scenarios for scaling.

Step 6: Deployment and Security

• Deploy integrations on secure cloud platforms (AWS, Azure, GCP).
• Use secret managers to store API credentials securely.
• Enforce HTTPS/TLS encryption for all data transmissions.
• Implement real-time monitoring, transaction logging, and error alerting.

Step 7: Maintenance and Monitoring

• Monitor Extensiv Order Manager API changes and status pages.
• Set alerts for authentication failures, API downtime, or data discrepancies.
• Track KPIs like order sync rates, inventory accuracy, and fulfillment speed.

Optional Enhancements

• Middleware integration (e.g., MuleSoft, Celigo, Boomi) for easier cross-platform workflows.
• Real-time dashboards for inventory and order management.
• Webhook-driven event notifications for immediate updates.

Summary

Building strong Extensiv Order Manager integrations empowers businesses to automate multi-channel fulfillment, improve inventory visibility, and scale efficiently. This DIY Developer Guide for Extensiv Order Manager provides a structured framework for secure, scalable, and reliable custom integrations.
