ApplicationInterchangeId for End-to-End Correlation

How does ApplicationInterchangeId enable end-to-end correlation?

ApplicationInterchangeId is a correlation identifier that tracks business transactions across multiple systems, platforms, and integration hops—enabling end-to-end visibility from order entry to fulfillment regardless of technology boundaries.

The Problem Without Correlation IDs

Without ApplicationInterchangeId:

  • ❌ Order 12345 enters via webMethods → logs show "MessageId: wm-abc123"
  • ❌ Custom API processes order → logs show "RequestId: req-98765"
  • ❌ IBM Sterling ships order → logs show "TransmissionId: ib-xyz789"
  • ❌ No way to connect these 3 log entries—troubleshooting requires manually correlating timestamps, Order Numbers, Customer IDs across 3 separate log systems

Troubleshooting time: 2-3 hours hunting across platforms.

The Solution: ApplicationInterchangeId

With ApplicationInterchangeId:

  • ✅ Order 12345 enters via webMethods → logs ApplicationInterchangeId: "550e8400-e29b-41d4-a716-446655440000"
  • ✅ Custom API processes order → logs same ApplicationInterchangeId: "550e8400-e29b-41d4-a716-446655440000"
  • ✅ IBM Sterling ships order → logs same ApplicationInterchangeId: "550e8400-e29b-41d4-a716-446655440000"
  • ✅ Nodinite correlates automatically—search for correlation ID, see all 3 systems' logs in unified timeline

Troubleshooting time: 30 seconds—search once, see entire transaction journey.

How to Implement ApplicationInterchangeId

1. Generate Correlation ID at Entry Point

When transaction enters your integration landscape, generate a unique correlation ID:

// .NET example
string correlationId = Guid.NewGuid().ToString();
// Result: "550e8400-e29b-41d4-a716-446655440000"

// Java example
String correlationId = UUID.randomUUID().toString();

# Python example
import uuid
correlation_id = str(uuid.uuid4())

2. Include in JSON Log Event

Set ApplicationInterchangeId field in every JSON Log Event:

{
  "LogAgentValueId": 42,
  "EndPointName": "webMethods - Receive Order",
  "OriginalMessageTypeName": "PurchaseOrder#1.0",
  "ApplicationInterchangeId": "550e8400-e29b-41d4-a716-446655440000",
  "LogMessage": "Order received from customer",
  "Body": "<Order><OrderId>12345</OrderId>...</Order>"
}

3. Propagate Across Systems

Pass correlation ID to downstream systems:

  • HTTP headers: X-Correlation-ID: 550e8400-...
  • Message properties: JMS headers, Azure Service Bus user properties, RabbitMQ headers
  • Message body: Include in XML/JSON payload: <CorrelationId>550e8400-...</CorrelationId>

Each system logs with same ApplicationInterchangeId:

// Custom API logs
{
  "ApplicationInterchangeId": "550e8400-e29b-41d4-a716-446655440000",
  "EndPointName": "Custom API - Process Order",
  "LogMessage": "Order validated, calling IBM Sterling"
}

// IBM Sterling logs
{
  "ApplicationInterchangeId": "550e8400-e29b-41d4-a716-446655440000",
  "EndPointName": "IBM Sterling - Ship Order",
  "LogMessage": "Shipment created, tracking number 1Z999..."
}

End-to-End Visualization with BPM

Business Process Modeling (BPM) uses ApplicationInterchangeId to visualize transaction flows:

  1. Define BPM process - "Order to Cash": webMethods → Custom API → IBM Sterling → SAP
  2. Configure Message Types - Map "PurchaseOrder#1.0" → "OrderConfirmation#1.0" → "Shipment#1.0" → "Invoice#1.0"
  3. Nodinite correlates automatically - Groups logs by ApplicationInterchangeId, displays graphical timeline

Result: Visual flow diagram showing Order 12345's journey across 4 systems with timestamps, status, delays.

Real-World Example

Healthcare company: Patient claim flows through 8 platforms:

  1. webMethods receives EDI 837 claim → generates ApplicationInterchangeId
  2. Custom .NET service validates claim → logs with same ApplicationInterchangeId
  3. Apache Camel routes to payer API → logs with same ApplicationInterchangeId
  4. MuleSoft transforms response → logs with same ApplicationInterchangeId
  5. ... (4 more hops)

Without correlation: 2-3 hours manually matching timestamps, claim IDs across 8 log systems
With ApplicationInterchangeId: 90 seconds—search correlation ID once, see entire claim lifecycle

95% faster troubleshooting.

Best Practices

  • ✅ Generate at entry point - First system creates correlation ID, propagates downstream
  • ✅ Use UUID/GUID format - Universally unique, no collisions: 550e8400-e29b-41d4-a716-446655440000
  • ✅ Propagate via headers AND body - Redundancy ensures reliability if headers stripped
  • ✅ Log at every hop - Every system writes JSON Log Event with ApplicationInterchangeId
  • ✅ Include in error messages - When errors occur, correlation ID enables instant troubleshooting
  • ⚠️ Never reuse correlation IDs - Each transaction gets unique ID
