Ad attribution that actually fires on COD orders

Shopify's built-in pixel integration tracks standard checkout — not COD. Preventify fires the right events (InitiateCheckout, Purchase, and more) to Meta, TikTok, and Snapchat the moment a COD order is placed, so your ROAS data is finally accurate.

The Problem

Shopify's default pixel fires on standard checkout — not COD

When you bypass Shopify checkout with a COD form, Shopify's built-in pixel integration never sees the purchase event. Your Meta Ads Manager shows zero conversions while your orders keep coming in — making ROAS look terrible and starving the algorithm of data.

Platform Support

Every major ad platform your performance team runs

One Preventify integration handles Meta, TikTok, Snapchat, and custom GTM — so you don't need a separate setup per platform.

Full Conversions API (CAPI) server-side delivery for maximum match rate — even with ad blockers active.

Server-Side Delivery

Events that reach the platform — even through ad blockers

Client-side pixels are blocked by browsers and ad blockers at increasing rates. Preventify fires events server-side via each platform's Conversions API — so you capture the conversions your competitor's pixel misses.

  • Dual delivery (server + client)Deduplication handled automatically — events aren't counted twice in your ad account.
  • Higher event match ratePhone number and order ID are sent as match keys alongside hashed PII — improving Meta's event match score.
  • Reliable in restricted regionsServer-side delivery works even in markets with heavy browser privacy restrictions.

Common Questions

Frequently asked

Why doesn't Shopify's built-in Meta pixel track COD orders?
Shopify's pixel fires events on the standard Shopify checkout flow. When you replace that checkout with a COD form, the order is created via the API and Shopify's pixel never sees it. Preventify hooks directly into the order creation event and fires to each platform independently.
Will events be duplicated if I have both Shopify's native pixel and Preventify?
No duplication issue — because Shopify's native pixel doesn't fire on COD form orders at all. If you ever mix checkout flows, Preventify includes deduplication logic using the order ID as the event ID.
Do I need to configure the Meta Conversions API separately?
No. Preventify handles the CAPI connection for you. Just enter your pixel ID and access token in the Preventify dashboard — no developer setup, no direct Meta API work.
Can I run pixels for multiple brands on the same Shopify store?
Yes. Add as many pixel IDs as you need for Meta, TikTok, or Snapchat. Every order fires to all configured pixels simultaneously — ideal for agency setups or multi-brand stores.
Is pixel tracking available on the free plan?
Yes — Meta, TikTok, and Snapchat pixel integration is included on all plans including Free (within the 200-order/month limit). Multiple pixels per platform and Conversions API are available on Basic and Pro plans.
