SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a robust, production-ready system for sending notifications across multiple channels, ensuring messages reach users effectively and securely.

Core Features & Use Cases

  • Multi-Channel Delivery: Send notifications via Email (SendGrid), Push (OneSignal), In-App (WebSockets), and Webhooks (Slack/Discord).
  • OWASP Security: Implements security best practices to prevent common vulnerabilities like broken access control and injection attacks.
  • Smart Routing & Fallback: Intelligently selects the best channel based on priority and user preferences, with automatic fallback mechanisms if a primary channel fails.
  • User Control: Allows users to manage their notification preferences and opt-out of non-essential communications.
  • Use Case: Automatically send a critical security alert via email and push notification if an unusual login is detected, with a fallback to email if push fails.

Quick Start

Use the Notification Universal skill to send a critical alert to user 'user-123' with the title 'Security Alert' and body 'Unusual login detected'.

Frequently Asked Questions about Notification Universal - Production Multi-Channel Notifications

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I send multi-channel notifications across email, push, and webhooks?▼

A multi-channel notification system delivers messages via email, push, in-app, and webhooks simultaneously. It integrates SendGrid, OneSignal, WebSockets, and Slack/Discord to ensure reliable message delivery with automatic fallback mechanisms.

What is the best way to handle notification delivery failures with a fallback mechanism?▼

Smart routing with fallback mechanisms handles delivery failures by automatically rerouting messages. If a primary channel like push fails, the system redirects the notification to an alternative channel like email to ensure reliable delivery.

Does this notification system comply with OWASP security best practices?▼

Yes, the system implements OWASP security compliance to prevent common vulnerabilities like broken access control and injection attacks. This ensures secure message delivery and webhook communication across all integrated channels.

How do I manage user notification preferences and opt-out controls?▼

The system manages user preferences by allowing individuals to select preferred channels and opt-out of non-essential communications. Smart routing uses these settings to deliver messages only through user-authorized channels.

Can I use SendGrid and OneSignal together for critical security alerts?▼

Yes, you can integrate SendGrid for email and OneSignal for push notifications simultaneously. The system routes critical security alerts across both channels and applies fallback mechanisms if either delivery method fails.

When do I need webhook delivery for in-app notifications?▼

You need webhook delivery when pushing event-driven updates to external platforms like Slack or Discord. While WebSockets handle internal in-app notifications, webhooks extend reach to external communication endpoints for comprehensive message delivery.
