Facebook Conversion API (Server-Side)

Recover the 30-60% of conversion data iOS 14.5+ broke — and teach Meta's algorithm on real revenue.

The problem
iOS 14.5+ broke the pixel. You're losing 30-60% of conversion data — Meta's algorithm is optimizing on noise, your CPL is climbing, and your reports lie about ROAS.
  • 60% of conversions lost without server-side tracking after iOS 14.5+
  • +10-15% ad efficiency on average after CAPI deployment
  • CPL drops 15-30% within 2 weeks as Meta re-learns on clean data
Our solution

Server-side event delivery via Make.com → Facebook Conversion API. Lead, Schedule, Purchase, and custom events fire from your CRM with hashed email, phone (E.164), name, city, and IP — Meta sees the full conversion within 15-30 minutes regardless of browser tracking.

How it works
  1. 01
    Event mapping
    Identify the events that matter: Lead (form submit), Schedule (call booked), Purchase (Shopify/Stripe payment), and any custom funnel steps.
  2. 02
    Make.com router
    Each event source (Pipedrive stage change, Cal.com booking, Shopify order) routes through one Make scenario.
  3. 03
    Data hashing
    Email lowercased + SHA-256, phone normalized to E.164 + SHA-256, name + city + IP packaged per Meta's CAPI spec.
  4. 04
    Send to Conversion API
    POST to graph.facebook.com Conversion API with proper event_id for deduplication against pixel events.
  5. 05
    Dedup with pixel
    Same event_id used by client-side pixel and server-side CAPI — Meta merges them, no double-count.
  6. 06
    Verify in Events Manager
    Test events with Test Event Code, monitor Event Match Quality (target 7+), validate within 48 hours.
