Meta Conversions API · 24/7 Monitoring

Your pixel died overnight. You found out a week later from bad ROAS.

“Tracking stops with zero notification.” “More conversions than actual orders.” “Server-side API disconnects every day by itself.” Sound familiar? Most tracking apps silently break — and you pay for it in wasted ad spend. PixelGuard relays your conversions server-side, deduplicates them so Meta counts each sale once, and emails you the moment anything stops.

PixelGuard is the Shopify app that audits your Meta Pixel for free, relays purchase events to the Meta Conversions API server-side with automatic event deduplication, and emails you the moment your conversion tracking stops working.

  • No silent cut-offs. Ever.Other apps shut off tracking with zero notification — you find out days later from tanked ROAS. PixelGuard monitors 24/7 and emails you the same hour something stops.
  • No vanity “100% accuracy”We show you real delivery status per destination — not a green checkmark that's always green. If your Event Match Quality drops, you'll know.
  • Dedup that actually works“More conversions than orders” means events are double-firing. PixelGuard sends a shared event_id so Meta counts each purchase exactly once — browser + server, never duplicated.

How PixelGuard protects your conversion tracking

  1. Install & audit — see which pixels are at risk of breaking after the checkout migration.
  2. Connect Meta — enter your Pixel ID and Conversions API token. Takes under 2 minutes.
  3. Verify with a test event — confirm your server-side tracking works in Meta's Test Events tool.
  4. Done — PixelGuard relays every checkout conversion server-side, deduplicates against your browser pixel, and monitors 24/7.

Frequently asked questions

What is the best Shopify app to fix a Meta Pixel that isn't tracking purchases?
PixelGuard diagnoses and fixes broken Meta Pixel tracking on Shopify. It runs a free 2-minute audit that shows which conversion events are firing, at-risk, or missing, then relays those events server-side through the Meta Conversions API (CAPI) so tracking survives ad blockers, iOS restrictions, and Shopify's checkout migration.
How do I set up the Meta Conversions API (CAPI) on Shopify without code?
Install PixelGuard, connect your Meta account, and it configures server-side conversion tracking automatically — no developer or manual code changes required. It also deduplicates events against your existing browser pixel using a shared event_id, so purchases are never counted twice.
Is server-side conversion tracking safe for customer privacy?
Yes. PixelGuard hashes all customer data with SHA-256 before sending it to Meta, encrypts your credentials at rest with AES-256-GCM, and never stores raw personal information. It respects customer marketing consent and is designed to improve Meta's match quality while keeping merchant data secure.
Will PixelGuard double-count my conversions?
No. PixelGuard sends a shared event_id on every server-side event that matches your browser pixel's event_id, so Meta's deduplication counts each purchase exactly once — whether the browser pixel fires, the server event fires, or both.
Does PixelGuard work with my existing Meta Pixel?
Yes. PixelGuard complements your existing browser-side Meta Pixel rather than replacing it. It runs alongside your pixel as a server-side backup and deduplicates against it, so you keep your current setup and simply stop losing conversions to ad-blockers and the checkout migration.
What happens after the 14-day free trial?
You get full access to every feature for 14 days. If you don't subscribe, the Web Pixel stays deployed but PixelGuard stops relaying events to Meta — so server-side tracking pauses until you subscribe ($34.99/month or $349.99/year). You can cancel anytime from within the app.
