How It Works: Operational Flow

The Message Processor follows a systematic workflow that ensures reliable, secure processing of payment messages. Here's a detailed breakdown of each stage:

Message Processor working principle

1. Inbound Connection

  • Message Reception

    • Accepts incoming messages from multiple sources:
      • Bank APIs
      • Financial gateways
      • External systems
    • Validates message format and structure
    • Assigns unique transaction identifier

  • Queue Management

    • Places messages in inbound queue
    • Maintains message priority
    • Ensures ordered processing

2. Workflow Processor

  • Message Retrieval

    • Pulls messages from inbound queue
    • Maintains processing order
    • Manages throughput based on system capacity

  • Workflow Selection

    • Matches messages to appropriate workflows based on:
      • Payment type
      • Originator
      • Geographic region
      • Message attributes
    • Retrieves workflow definition from storage

3. Workflow Execution

The system processes messages through a flexible combination of:

  • Enrichment tasks
  • Validation processes
  • Transformation operations

These steps can be repeated and reordered based on workflow requirements.

4. Error Management

  • Error Detection

    • Monitors processing steps
    • Identifies validation failures
    • Catches system errors
    • Flags data inconsistencies

  • Recovery Procedures

    • Implements retry logic for transient errors
    • Routes to error queue when needed
    • Enables manual intervention
    • Maintains processing state

5. Outbound Processing

  • Message Dispatch

    • Routes to designated endpoints
    • Supports multiple destinations
    • Ensures secure transmission
    • Verifies delivery

  • Confirmation Handling

    • Processes acknowledgments
    • Updates transaction status
    • Maintains delivery records
    • Handles failed deliveries
