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 and emails you the moment anything stops.

PixelGuard is the Shopify app that compares the orders your store actually took against how many your checkout tracking actually fired on, shows the gap in money daily for free, and relays purchase events to the Meta Conversions API server-side on the paid plan.

Paste your store address and see which Meta pixel IDs it fires — and whether two of them are firing and double-counting your sales.

  • 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.
  • We catch double-tracking before it costs you“More conversions than orders” means two integrations are both sending Purchase. The free audit detects that and warns you before you turn anything on.
  • We're not a replacement for Shopify's Meta channel. We're the check on it.Shopify's native Facebook & Instagram channel sends events to Meta. It has nothing to compare its own count against and it will never tell you when it stops. PixelGuard reads your actual Shopify order ledger and shows you the difference — keep the native channel, and let us audit it.

How PixelGuard protects your conversion tracking

  1. Install & audit — see which pixels are at risk of breaking after the checkout migration, and whether your store already sends Purchase events to Meta.
  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 and monitors it 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. The audit first checks whether your store already sends Purchase events to Meta, so you don't end up with two integrations running at once.
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.
Why pay for PixelGuard when Shopify's Facebook & Instagram sales channel already sends conversions to Meta for free?
Because they answer different questions, and most PixelGuard users should keep the native channel running. Shopify's Facebook & Instagram channel sends events to Meta. It does not tell you whether they arrived, it has nothing to compare its own count against, and it will not notify you when it stops — which, judging by its own App Store reviews, it sometimes does. PixelGuard is the thing that checks it: it reads Shopify's own order ledger and compares it against how many of those orders your checkout tracking actually fired on, then prices the gap in your currency, daily. Nothing without access to your order data can do that, which is why no free pixel app does. The audit and that daily comparison are free in PixelGuard too — you are not paying for them. What $49.99/month buys is the fix: when the comparison shows a gap, PixelGuard relays the missing conversions to Meta server-side with hashed Advanced Matching. If you only want to know when the native channel breaks, stay on the free plan and connect nothing — the audit and the daily comparison run without any Meta credentials at all.
Will PixelGuard double-count my conversions?
Only if you run it alongside another Purchase event without turning one off. Shopify's Web Pixel sandbox can't share an event ID with a browser-side pixel, so PixelGuard is designed to be the single source of Purchase events, not a second one. The free audit detects whether your store already sends Purchase to Meta and warns you before you enable the relay — and monitor-only mode lets you keep your existing setup and just use PixelGuard's alerting.
Does PixelGuard work with my existing Meta Pixel?
It depends on what your existing setup does. If your browser pixel or Shopify's native Meta integration is already sending Purchase events successfully, run PixelGuard in monitor-only mode — you keep your setup and get alerted the moment it breaks. If your Purchase tracking is broken, blocked, or gone after the checkout migration, switch the relay on and PixelGuard becomes your source of truth.
What happens after the 14-day free trial?
You move to the free plan, not to nothing. The pixel audit, the daily tracking-accuracy report (your Shopify orders against how many your checkout tracking fired on) and the gap alert emails all keep running, forever, with no card required. What pauses is the paid part: PixelGuard stops relaying conversions to Meta server-side. Subscribe at $49.99/month or $499.99/year to turn it back on. Cancel anytime from within the app.
What do I get for free, and what do I have to pay for?
Free forever: the pixel audit, the daily tracking-accuracy report that compares your real Shopify order count against how many orders your checkout tracking actually fired on and prices the gap in your own currency, and an email alert when that gap gets large enough to matter. Paid ($49.99/month): the fix — PixelGuard relays your conversions to Meta server-side via the Conversions API with hashed Advanced Matching, plus 24/7 delivery monitoring and a weekly health digest.
