SignalRelay Documentation

SignalRelay is a multi-platform server-side conversion tracking engine for WordPress built specifically for lead generation, professional services, rental properties, and real estate.

It delivers conversion events directly to Meta, TikTok, Google, and Pinterest through their official server-to-server APIs (Conversions API / Events API), solving the 20% to 40% loss caused by ad blockers, iOS/ITP, and third-party cookie deprecation.

What Makes SignalRelay Different?

  1. True Cache-Safe Deduplication: The event_id is generated inside the visitor’s browser at runtime. If your site runs a full-page cache like WP Rocket, LiteSpeed, or Cloudflare, it will never freeze a shared ID across visitors.
  2. First-Party Identity Persistence: Maintains an anonymous first-party visitor identifier and captures campaign parameters (utm_*, fbclid, ttclid, gclid) to preserve attribution even after cookies expire.
  3. Privacy by Design: Native integration with the official WP Consent API and Google Consent Mode v2. All personally identifiable information (email, phone) is hashed using SHA-256 on your server before transmission.
