ShipRush is a shipping and order management solution that helps businesses streamline carrier connections, automate label printing, and optimize fulfillment workflows. This DIY Developer Guide for ShipRush provides a comprehensive approach to building secure, scalable, and efficient custom integrations with eCommerce platforms, ERP systems, and third-party logistics providers.

Prerequisites for ShipRush Integrations

• ShipRush Developer Account and API Access
• API Key or OAuth credentials
• Familiarity with:
  • RESTful APIs
  • OAuth 2.0 Authentication
  • JSON data formatting
• Tools: Postman, ShipRush API Documentation, SDKs (Python, Node.js)

Step 1: Authentication for ShipRush Integrations

ShipRush APIs use OAuth 2.0 for secure access.

Authentication Example:

POST https://api.shiprush.com/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 received access_token in the Authorization header for all API requests.

Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

• Shipments
• Labels
• Carriers
• Rates
• Tracking Information

Process:

• Study ShipRush API documentation thoroughly.
• Map eCommerce or ERP system fields (e.g., order ID, shipping address) to ShipRush data models.

Important considerations:

• Accurate address formatting for carrier validation
• Proper package dimensions and weight for rate calculation
• Consistent order and shipment ID mapping across systems

Step 3: Building Integration Workflows

Integration Patterns:

• Inbound (to ShipRush): Submit orders for label generation, update shipment details.
• Outbound (from ShipRush): Retrieve tracking information, carrier rates, and shipment statuses.

Example: Creating a Shipment

POST /api/shipments
{
  "recipient": {
    "name": "Jane Smith",
    "address1": "123 Main St",
    "city": "Seattle",
    "state": "WA",
    "postalCode": "98101",
    "country": "US"
  },
  "package": {
    "weight": 5.5,
    "dimensions": "10x8x4"
  },
  "carrier": "FedEx"
}

Example: Fetching Tracking Info

GET /api/shipments/{shipmentId}/tracking
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

• Capture HTTP status codes and ShipRush-specific error messages.
• Implement retry mechanisms for 429 (rate limiting) and transient 5xx errors.

Pagination:

• Use page and pageSize parameters for large data pulls.

Example:

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

Step 5: Testing and Validation

• Test API workflows with Postman and ShipRush sandbox environment (if available).
• Validate shipment creation, label generation, and tracking updates.
• Perform load testing for bulk order shipping scenarios.

Step 6: Deployment and Security

• Deploy integration services securely on cloud platforms (AWS, Azure, GCP).
• Store credentials securely using secret managers.
• Enforce HTTPS/TLS encryption for all communications.
• Enable real-time logging, monitoring, and error alerting.

Step 7: Maintenance and Monitoring

• Monitor ShipRush API updates and deprecations.
• Set up real-time alerts for API errors and integration downtimes.
• Track KPIs like label generation speed, shipment success rates, and carrier cost optimization.

Optional Enhancements

• Middleware integration (Celigo, Boomi, MuleSoft) for complex cross-platform workflows.
• Dashboards for real-time tracking of shipments and carrier performance.
• Event-driven webhook notifications for shipment status changes.

Summary

Building custom ShipRush integrations enables businesses to automate shipping operations, reduce label processing time, and optimize carrier selection. This DIY Developer Guide for ShipRush offers a secure, scalable framework for developing high-performance integrations tailored to fulfillment and logistics workflows.
