Integration Patterns

Pattern 1: Synchronous API Integration

┌─────────────┐     ┌─────────────┐     ┌─────────────┐
│   Client    │────▶│  Cloud API  │────▶│  External   │
│ Application │     │             │     │   Service   │
│             │◀────│             │◀────│             │
└─────────────┘     └─────────────┘     └─────────────┘
       │                   │                   │
       │   HTTP Request    │   HTTP Request    │
       │──────────────────▶│──────────────────▶│
       │                   │                   │
       │   HTTP Response   │   HTTP Response   │
       │◀──────────────────│◀──────────────────│

Use Cases:

  • Real-time policy quoting
  • Address validation
  • Credit scoring
  • Real-time fraud detection
// Synchronous integration example
async function getRealTimeQuote(submissionId: string): Promise<Quote> {
  // Call external rating engine
  const ratingResponse = await ratingService.calculatePremium({
    submissionId,
    effectiveDate: submission.effectiveDate,
    coverages: submission.coverages
  });

  // Update Guidewire with results
  return await guidewireClient.updateQuote(submissionId, {
    premium: ratingResponse.premium,
    taxes: ratingResponse.taxes,
    fees: ratingResponse.fees
  });
}

Pattern 2: Asynchronous Event-Driven

┌─────────────┐     ┌─────────────┐     ┌─────────────┐     ┌─────────────┐
│ InsuranceSuite │──▶│  App Events │──▶│    Kafka    │──▶│  Consumer   │
│             │     │   Service   │     │   Topic     │     │  Service    │
└─────────────┘     └─────────────┘     └─────────────┘     └─────────────┘
       │                   │                   │                   │
       │  Business Event   │   Publish Event   │   Consume Event   │
       │──────────────────▶│──────────────────▶│──────────────────▶│
       │                   │                   │                   │
       │                   │                   │   Process Async   │
       │                   │                   │                   │

Use Cases:

  • Policy issued notifications
  • Claims status updates
  • Billing events
  • Data warehouse synchronization

Pattern 3: Batch Integration

┌─────────────┐     ┌─────────────┐     ┌─────────────┐     ┌─────────────┐
│    SFTP     │────▶│    Batch    │────▶│  Transform  │────▶│ InsuranceSuite │
│   Server    │     │   Pickup    │     │   & Load    │     │             │
└─────────────┘     └─────────────┘     └─────────────┘     └─────────────┘
       │                   │                   │                   │
       │   Drop File       │   Schedule Job    │   Process Data    │
       │──────────────────▶│──────────────────▶│──────────────────▶│

Use Cases:

  • Nightly policy updates
  • Bulk claims import
  • Premium bordereaux
  • Regulatory reporting
