Webhooks Module

The Webhooks Module provides comprehensive webhook management capabilities, enabling real-time event processing, third-party integrations, and automated workflow triggers throughout the DashClicks platform.

Brief Overview

The Webhooks module serves as the central hub for webhook management, processing incoming webhooks from various third-party services, managing outgoing webhook deliveries, and providing comprehensive logging and monitoring capabilities. It ensures reliable event-driven communication between DashClicks and external platforms.

Background Processing

Queue Manager Integration

The Webhooks module relies heavily on Queue Manager for reliable webhook operations:

Webhook Processing (QM_WEBHOOKS_PROCESSING=true)

• Asynchronous incoming webhook processing
• Payload transformation and validation
• Event distribution to appropriate handlers
• Error handling and recovery operations

Delivery Management (QM_WEBHOOKS_DELIVERY=true)

• Outgoing webhook delivery processing
• Retry logic for failed deliveries
• Exponential backoff and rate limiting
• Dead letter queue management

Monitoring & Health Checks (QM_WEBHOOKS_MONITORING=true)

• Webhook endpoint health monitoring
• Performance metric collection
• Failure detection and alerting
• Subscription status validation

Retry Processing (QM_WEBHOOKS_RETRY=true)

• Failed webhook retry scheduling
• Exponential backoff implementation
• Maximum retry limit enforcement
• Dead letter queue processing

Analytics Processing (QM_WEBHOOKS_ANALYTICS=true)

• Webhook performance analytics aggregation
• Delivery success rate calculation
• Response time monitoring
• Integration health reporting
