WeSupply is a post-purchase experience platform that offers shipment tracking, order notifications, returns management, and in-store pickup solutions for eCommerce businesses. This DIY Developer Guide for WeSupply provides a structured framework for building secure, scalable, and efficient custom integrations with eCommerce platforms, ERP systems, and customer experience solutions.

Prerequisites for WeSupply Integrations

• WeSupply API access credentials (API Key)
• Familiarity with:
  • RESTful APIs
  • OAuth 2.0 or API Key Authentication
  • JSON data formatting
• Tools: Postman, WeSupply API Documentation, SDKs (Python, Node.js)

Step 1: Authentication for WeSupply Integrations

WeSupply APIs use API Key authentication.

Authentication Example:

Authorization: ApiKey YOUR_API_KEY

All API traffic must be sent over HTTPS.

Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

• Orders
• Shipments
• Returns
• Notifications
• Store Locations

Process:

• Review WeSupply API documentation thoroughly.
• Map your ERP or eCommerce platform fields (e.g., order ID, customer email) to WeSupply fields.

Important considerations:

• Proper mapping of order and tracking information
• Ensuring return reasons and statuses are standardized
• Store location data structure for in-store pickup solutions

Step 3: Building Integration Workflows

Integration Patterns:

• Inbound (to WeSupply): Push new orders, shipment updates, and returns data.
• Outbound (from WeSupply): Retrieve customer notifications, return statuses, and store pickup availability.

Example: Creating an Order

POST /api/orders
{
  "orderNumber": "ORDER12345",
  "customerEmail": "customer@example.com",
  "items": [
    { "sku": "SKU001", "quantity": 2 }
  ]
}

Example: Retrieving Return Status

GET /api/returns/RETURN_ID
Authorization: ApiKey YOUR_API_KEY

Step 4: Error Handling and Pagination

Error Handling:

• Capture HTTP status codes and WeSupply-specific error messages.
• Implement retries for rate limits (429) and server errors (5xx).

Pagination:

• Use page and pageSize parameters for large result sets.

Example:

GET /api/orders?page=2&pageSize=50

Step 5: Testing and Validation

• Validate order creation, shipment updates, and return management workflows.
• Use Postman or sandbox environments for full API testing.
• Conduct load testing for high-volume order and return syncs.

Step 6: Deployment and Security

• Deploy integrations on secure cloud platforms (AWS, Azure, GCP).
• Store API Keys securely using secret managers.
• Enforce HTTPS/TLS for all data transmission.
• Implement real-time error monitoring and detailed logging.

Step 7: Maintenance and Monitoring

• Monitor WeSupply API status updates and releases.
• Set real-time alerts for failed transactions.
• Track KPIs such as notification delivery rates, return processing times, and store pickup success rates.

Optional Enhancements

• Middleware integration (MuleSoft, Celigo, Boomi) for cross-platform automation.
• Real-time dashboards for post-purchase journey monitoring.
• Webhook implementations for instant shipment and return status updates.

Summary

Building custom WeSupply integrations enables businesses to deliver outstanding post-purchase experiences, enhance customer satisfaction, and streamline returns and pickups. This DIY Developer Guide for WeSupply provides a complete blueprint for building secure, scalable, and efficient integrations.
