Need to setup Meta Pixel & CAPI for 2 Websites

I need a complete Meta Pixel and server-side Conversions API rollout for two WordPress sites. , so the job starts from a clean slate and must follow Meta’s latest iOS 14+ guidelines.

My overarching aim is to lift overall ad performance by tracking every lead, WhatsApp, and Messenger action with zero data loss. That means full domain verification, event deduplication, and rigorous testing inside Meta Events Manager until every event fires once—and only once—across browser and server.

Deliverables
• Install Meta Pixel on both domains
• Build and connect server-side CAPI, including multi-domain mapping
• Verify each domain and configure eight-event prioritisation
• Set up lead, WhatsApp, and Messenger conversion events with deduplication
• Test, troubleshoot, and supply proof of accurate firing (screenshots or Loom walkthrough)

When you reply, please outline:

I’ll review proposals as they arrive and move quickly once I see a solid fit.
