n8n workflow that sends server-side

n8n workflow that sends server-side conversion events straight to Meta Conversions API, bypassing browser blockers for accurate ad attribution. Problem: iOS 14+ and ad blockers were breaking browser-based Meta Pixel tracking, businesses were losing conversion data and making ad spend decisions on incomplete numbers.

Solution: Built a server-side webhook workflow that receives conversion events, sanitizes and SHA-256 hashes personal data to meet Meta's privacy standards, formats the payload with click IDs and user info, and sends it directly to Meta's Conversions API, bypassing the browser entirely.

Result: Accurate conversion tracking and attribution, no more data loss from blockers.
