About Amanda Trends and Venture
Amanda Trends and Venture (amandatrendsandventure.org) is an online store built on Wix, with its Meta Pixel connected through Wix's built-in Meta partner integration.
Project overview
Amanda Trends and Venture's Wix store already sent browser events to Meta through Wix's partner integration, but browser-only events are exposed to ad blockers and tracking prevention. The store needed a Conversions API layer that could send the same funnel events from a server without double counting them.
I built a web GTM container that pairs each Meta event with a server-bound GA4 event, routed that stream to a server-side GTM container on Stape behind a custom tracking subdomain, and forwarded it to Meta and GA4. Every step was checked in GTM preview, GA4 DebugView and Meta Events Manager test events.
Goals
- Send PageView, ViewItemList, ViewContent, AddToCart, InitiateCheckout and Purchase through the Conversions API
- Deduplicate server events against the browser events from Wix's Meta integration
- Serve server-side tracking from a first-party tracking subdomain
- Track the GA4 ecommerce funnel from product list to purchase
- Capture Wix checkout steps such as contact and address info submission
Challenges
- Browser-only Pixel events are lost to ad blockers and tracking prevention
- Wix already fires its own browser Pixel events, so server events had to match them for deduplication
- Wix checkout steps are not standard GA4 ecommerce events
- One GA4 stream had to feed both Meta and GA4 from the server container
Strategy
I kept Wix's Meta partner integration for browser events and added a server-side layer next to it. In web GTM, Meta Pixel tags sit alongside matching "Fb Server" GA4 event tags that send each interaction to a server-side GTM container on Stape, served from a custom tracking subdomain. There, a Conversions API tag forwards the events to Meta with event IDs that line up with the browser events, so Meta deduplicates the pair, while a GA4 tag records the same ecommerce stream.
What I implemented
Web GTM container
- Meta Pixel browser tags for PageView, View Item List, ViewContent, AddToCart, Checkout and Purchase
- Matching "Fb Server" GA4 event tags that send each interaction to the server container
- GA4 events for Contact Info Submit and Address Info Submit on the Wix checkout
- GA4 configuration tag on all pages
Server-side GTM on Stape
- Conversions API tag fired from the incoming Meta event stream
- GA4 ecommerce tracking tag fired on all GA4 events
- Stape container on a custom tracking subdomain, verified as Ready with a CNAME record
GA4 eCommerce
- page_view, ViewItemList, view_item, add_to_cart, begin_checkout and purchase events
- Verified the full sequence in GA4 DebugView during a test order
QA in Meta Events Manager
- Test events checked for PageView, ViewItemList, View content, Add to cart, Initiate checkout and Purchase
- Browser copies received through the Wix partner integration and server copies through the manual CAPI setup
- Server copy of each event marked as deduplicated
- Wix's own WixOrderPlaced event confirmed alongside Purchase on the test order
Tools used
Results
- Purchase and Initiate checkout received from both browser and server, with the server copy deduplicated
- Add to cart, View content, ViewItemList and PageView received from browser and server and deduplicated
- Server-side Conversions API and GA4 ecommerce tags each fired 13 times in preview, with no tags left unfired
- Full GA4 funnel from page_view through view_item, add_to_cart and begin_checkout to purchase verified in DebugView
- Custom tracking subdomain live on Stape, with 559 requests sent in the current cycle
