This DIY Developer Guide for DSCO provides a complete roadmap for building secure, scalable, and efficient custom integrations. DSCO, now part of CommerceHub, is a cloud-based supply chain management platform that simplifies dropshipping and vendor-direct fulfillment with APIs for order management, inventory updates, and shipment tracking.

Whether you’re syncing product inventory, automating order processing, or tracking fulfillment, mastering DSCO integrations ensures better supply chain visibility and faster delivery performance.

Prerequisites for DSCO Integrations

• DSCO (CommerceHub) Account and API Access
• API Credentials (API Key or OAuth Tokens)
• Familiarity with:
  • RESTful APIs
  • JSON data structures
  • OAuth 2.0 Authentication
• Tools: Postman, DSCO API Documentation, SDKs (Node.js, Python)

Step 1: Authentication for DSCO Integrations

DSCO APIs support API Key authentication and OAuth 2.0.

Example Authentication (Header):

Authorization: Bearer YOUR_ACCESS_TOKEN

For some endpoints, you may also pass the API Key directly in the header.

Step 2: Endpoint Discovery and Data Mapping for DSCO Integrations

Common API Resources:

• Inventory
• Orders
• Shipments
• Products
• Acknowledgments

Process:

• Study DSCO’s API documentation to understand data models and requirements.
• Map external fields (from ERP, WMS, or eCommerce platforms) carefully to DSCO’s objects.

Important considerations:

• Required vs. optional fields
• SKU matching across systems
• Accurate format for inventory quantities, shipping addresses, and tracking numbers

Step 3: Building the Integration Flow

Integration Patterns:

• Inbound (to DSCO): POST or PUT to update inventory, acknowledge orders, and upload shipment details.
• Outbound (from DSCO): GET to retrieve new orders, product details, and shipment tracking updates.

Example: Updating Inventory

POST /v3/inventory
{
  "inventory": [
    {
      "sku": "SKU12345",
      "quantity": 50
    }
  ]
}

Example: Retrieving New Orders

GET /v3/orders?status=new
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

• Capture and log HTTP status codes and DSCO-specific error messages.
• Implement retries for 429 (rate limit) and 5xx (server error) responses.

Pagination:

• Use page and page_size query parameters to navigate large datasets.

Example:

GET /v3/orders?page=2&page_size=100

Step 5: Testing and Validation

• Use Postman and the DSCO Sandbox environment for testing.
• Validate correct inventory updates, order acknowledgments, and shipment tracking uploads.
• Perform load testing for bulk inventory and order sync scenarios.

Step 6: Deployment and Security

• Deploy integrations securely on cloud platforms (AWS, Azure, GCP)
• Store API credentials securely (using Vault or encrypted storage)
• Enforce HTTPS/TLS encryption for all API communications
• Implement robust logging and real-time alerting for integration failures

Step 7: Maintenance and Monitoring

• Monitor DSCO API version changes and new feature announcements
• Set real-time alerts for failed transactions or credential expiration
• Track success rates for inventory syncing, order fulfillment, and shipment uploads

Optional Enhancements

• Middleware orchestration (Celigo, MuleSoft, Boomi)
• Admin dashboards for order and inventory tracking
• Webhooks (if supported) for real-time updates on order creation and shipment changes

Summary

Mastering DSCO integrations empowers businesses to automate dropshipping operations, enhance supply chain visibility, and improve fulfillment performance. This DIY Developer Guide for DSCO provides a comprehensive framework for building secure, scalable, and effective custom integrations.
