Practical Hook Examples

This is a library of production-ready hook recipes you can copy into /includes/hooks/ and adapt — each one is tested against the actual Mumara Campaigns codebase.

The examples cover the most common extension scenarios:

• CRM sync — push contacts to HubSpot or Salesforce on AddContact, EditContact, and DeleteContact, including access-token caching.

• Notifications — Slack alerts on StartBroadcast, CompleteBroadcast, and SystemPauseBroadcast; email alerts on sending-domain verification events.

• Webhooks — HMAC-signed webhooks on contact, open (EmailOpened), and click (LinkClicked) events.

• Analytics — send open/click/campaign metrics to a custom endpoint, or inject Google Analytics via the HeadEnd and BodyEnd output hooks.

• UI customization — dashboard widgets (addPageHtml), sidebar menu items (PrimaryMenu), and alert bars.

• Validation & compliance — block disposable email domains, MX checks, GDPR audit logging, and rate limiting.

• Automation — auto-tag contacts by engagement and start drip sequences on events.

A dedicated section documents extending the Plan & Usage page (/plan) via the plan_tabs, plan_sections, and plan_hide filter hooks — adding addon tabs and sections, hiding core entries, choosing between the visible (hide entirely) and available (locked "contact admin" state) closures, and reusing the shared plan._meter partial. Every example wraps external calls in try-catch and logs failures, so a broken integration never blocks core operations — follow the same pattern in your own hooks.
