Smart Alerting Hub is the central notification hub for WHMCS. Route 26 types of invoice, ticket, order, service, client, network, and admin events to 8 channels — Email, Slack, Telegram, Discord, WhatsApp, SMS, PagerDuty, or custom Webhooks — all managed from a unified dashboard.

Why Smart Alerting Hub

Most WHMCS installations rely on plain email notifications. As volume grows, important alerts get buried in inboxes, on-call staff miss after-hours incidents, and noise drowns out the signal. Smart Alerting Hub fixes this by routing the right events to the right channels, with deduplication, mute windows, on-call rotation, and digest batching.

26 WHMCS Events Out of the Box

Subscribe any channel to any combination of:

• Invoice events — created, paid, overdue, cancelled, refunded
• Ticket events — opened, replied, closed, priority changed, escalated
• Order events — placed, accepted, fraud, cancelled
• Service events — created, suspended, terminated, due soon
• Client events — signup, login from new IP, profile change
• Network / server events — server down, high load, daemon crash
• Admin events — admin login, failed login, settings change

Every event ships with contextual variables you can reference in custom message templates.

8 Notification Channels

The Free tier ships with Email plus one extra channel (Slack or Telegram). Pro unlocks the full lineup:

• Email — built on the standard WHMCS mail layer, no SMTP changes required
• Slack — incoming webhook with rich block formatting and per-channel routing
• Telegram — bot API with Markdown formatting and inline keyboards
• Discord — webhook with embeds and role mentions
• WhatsApp — via Twilio API for direct customer messaging
• SMS — Twilio, Vonage, and ClickSend support out of the box
• PagerDuty — Events API v2 for end-to-end incident response
• Custom Webhook — POST any JSON payload to in-house systems

Channel Health at a Glance

The dashboard widget tracks every configured channel and surfaces failures inline: last delivery status, recent error count, queue depth, and a one-click test-connection button. No more discovering that a Telegram bot token expired only after two weeks of missed pages.

Pro Tier: Deduplication, Mute Windows, Templates, On-Call

The Pro tier turns Smart Alerting Hub from a notification fan-out into a real incident response tool:

• Alert deduplication — fingerprint identical events and suppress repeats inside a configurable cooldown window
• Mute / silence periods — schedule maintenance windows where specific channels or event types are paused
• Custom message templates — Mustache-style {{variable}} placeholders with per-channel and per-event overrides
• On-call rotation — weekly recurrence plus event-type filtering, routing after-hours alerts to whoever is on shift
• Alert digest — hourly or daily batching for low-priority events keeps noisy channels readable
• Unlimited alerts with configurable history retention
