ABS Platform Integration Guide

This directory contains all integration-related documentation for the ABS Platform, covering external system connectivity, messaging patterns, and API integration strategies.

Integration Overview

The ABS Platform supports multiple integration patterns to connect with external systems:

• API Integration - REST and GraphQL APIs for synchronous operations
• Event Integration - MQTT messaging for asynchronous communication
• External Systems - CRM, ERP, payment processors, and IoT devices

Integration Documents

Core Integration Patterns

• Integration Guide - Comprehensive external system integration patterns
• MQTT Integration - Technical MQTT implementation and listener patterns
• Messaging Dictionary - Unified messaging conventions and topic structures

MQTT Integration

• Topic Conventions - MQTT topic naming standards
• Quick Reference - Developer checklists and patterns
• Integration Guide - MQTT development guide

Common Integration Scenarios

1. CRM/ERP Integration (Odoo)

• Customer sync via API calls
• Subscription management through GraphQL
• Payment events via MQTT messaging

2. Payment Processor Integration

• Transaction processing via REST APIs
• Payment confirmations via webhooks
• Status updates through MQTT events

3. IoT Asset Management (ARM)

• Asset allocation via GraphQL queries
• Real-time status via MQTT telemetry
• Command dispatch through message queues

4. Mobile/Web Applications

• Service requests via GraphQL mutations
• Real-time updates via MQTT subscriptions
• Authentication through JWT tokens

Integration Security

• Authentication: OAuth2, JWT tokens, API keys
• Encryption: TLS/SSL for all communications
• Data Protection: Field-level encryption for sensitive data
• Rate Limiting: Configurable limits per integration

Error Handling & Resilience

• Circuit Breaker Pattern: Fault tolerance for external services
• Retry Logic: Exponential backoff for transient failures
• Dead Letter Queues: Failed message handling
• Health Checks: Continuous monitoring of integration endpoints

Development Guidelines

1. Follow Message Conventions: Use standardized topic patterns and payload structures
2. Implement Error Handling: Include circuit breakers and retry logic
3. Add Health Checks: Monitor integration endpoint availability
4. Document APIs: Provide clear examples and response formats
5. Test Thoroughly: Include integration tests with mock services
