See how Sync Hub solves real-world banking data synchronization challenges across different scenarios. Each use case demonstrates practical applications of the integration patterns.

Customer Data Synchronization

The Challenge

Customer profile information originates from multiple sources—branch systems, call centers, digital channels, and third-party services. Keeping all systems synchronized in real-time while maintaining data quality and consistency is critical for delivering unified customer experiences. Business Impact:
  • Inconsistent customer data across channels leads to poor experiences
  • Manual data reconciliation is time-consuming and error-prone
  • Delays in synchronization affect compliance and risk management
  • Multiple point-to-point integrations increase complexity

The Solution

Integration Patterns Used:
  • File Processing for batch updates from branch system
  • Webhooks for real-time CRM updates
  • Event Publishing from digital banking changes
  • Multi-Consumer distribution to all downstream systems

Real-Time Transaction Distribution

The Challenge

Transactions occur across multiple channels—ATMs, point-of-sale, online banking, mobile apps. Each transaction must be visible immediately in digital channels, analyzed for fraud, recorded for compliance, and available for customer service—all in real-time. Business Impact:
  • Delayed transaction visibility frustrates customers
  • Fraud detection requires immediate transaction data
  • Multiple system queries create performance bottlenecks
  • Point-to-point integrations are fragile and hard to maintain

The Solution

Integration Patterns Used:
  • Event Streaming from core banking Kafka
  • Webhooks from card processor
  • Message consumers for payment gateway
  • Multi-Consumer distribution (5+ consuming systems)

Payment Processing Integration

The Challenge

Payment processors like Alacriti and Volante send status updates via multiple channels—webhooks for real-time notifications, daily settlement files, and event streams for transaction lifecycle. Each requires different handling but must result in consistent payment status across all systems. Business Impact:
  • Multiple integration points create complexity and maintenance burden
  • Payment status updates must be immediate for customer notifications
  • Settlement reconciliation requires batch file processing
  • Compliance requires complete audit trail of all payment activities

The Solution

Integration Patterns Used:
  • Webhooks for real-time payment status updates
  • File Processing for daily settlement files
  • Event Streaming for transaction lifecycle events
  • Event Enrichment to add customer/account context
  • Multi-Consumer distribution to all systems

Account Update Propagation

The Challenge

Account status changes, balance updates, and service modifications must propagate instantly to all systems. Delays cause inconsistent account information, failed transactions, and poor customer experiences. Business Impact:
  • Account holds not reflected immediately cause failed transactions
  • Balance updates delayed lead to overdraft issues
  • Service changes (card activated, account closed) take too long to propagate
  • Customer frustration from inconsistent account information

The Solution

Integration Patterns Used:
  • Event Streaming from core banking
  • Real-time event processing
  • Multi-Consumer distribution
  • Guaranteed delivery to critical systems

Batch Payment File Integration

The Challenge

Corporate customers submit bulk payment files containing thousands of payment orders. Each file requires validation, individual payment creation, processing orchestration, and results file generation—all while maintaining audit trail and handling errors gracefully. Business Impact:
  • Manual file processing is time-consuming and error-prone
  • Lack of real-time status updates frustrates corporate customers
  • Error handling requires manual intervention
  • Results file generation delays cause reconciliation issues

The Solution

Integration Patterns Used:
  • File Processing for bulk payment files
  • Event generation for each payment order
  • Multi-Consumer distribution for orchestration
  • Webhooks for payment status updates
  • File generation for results delivery

Real-Time Notification Distribution

The Challenge

Critical notifications—fraud alerts, large withdrawals, low balance warnings, loan approvals—must reach customers immediately across multiple channels while being logged for compliance and triggering appropriate workflows. Business Impact:
  • Delayed notifications reduce fraud prevention effectiveness
  • Multiple notification systems create inconsistent experiences
  • Compliance requires audit trail of all customer communications
  • Manual notification triggering is slow and error-prone

The Solution

Integration Patterns Used:
  • Event Publishing from source systems
  • Multi-Consumer distribution to all notification channels
  • Guaranteed delivery for critical alerts
  • Event logging for compliance

Common Success Patterns

Based on these use cases, several patterns emerge for successful Sync Hub implementations: Start with high-value, low-complexity: Begin with real-time notifications or simple event distribution. Quick wins build confidence and demonstrate value before tackling complex integrations. For example, start with transaction notifications before implementing full payment processing lifecycle. Combine patterns for complete solutions: Most real-world scenarios require multiple integration patterns. Banking integrations rarely fit a single pattern—vendors use multiple channels. Payment processors commonly use webhooks (real-time), files (settlement), and events (lifecycle). Design for multi-consumer from day one: Assume every event will eventually have multiple consumers. New consuming systems emerge over time (analytics, compliance, new channels). Transaction events initially serve digital banking, but later add fraud detection, CRM, and analytics. Prioritize guaranteed delivery: Implement retry logic and dead letter handling from the start. In banking, losing events means lost transactions, compliance violations, or customer issues. Payment status updates must reach digital banking even if systems are temporarily unavailable.
