Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featurePixelRelay sends your Shopify events server-to-server — orders, add to carts, checkout starts, and more — to Google Ads, Meta, TikTok, GA4, Bing, and Segment, with more integrations coming. Captures conversion data browser-based pixels often miss due to ad blockers, iOS, and cookie restrictions. Includes Enhanced Conversions, click ID capture, GDPR Consent Mode v2, and event deduplication.
Prism ties each Shopify order to the channel, campaign, ad set and ad that drove it. A first-party pixel and server-side tracking capture the journey. When a browser blocks the pixel, Prism rebuilds it from Shopify order data. Compare six attribution models or build your own, and send purchases to Meta Conversions API and Google Ads so they optimize on real sales.
- Server-side tracking that bypasses ad blockers, iOS & cookie blockers
- Sends events server-side to Google Ads, Meta, TikTok, GA4, Bing, and Segment
- Order webhooks catch every purchase — even when browser pixels are blocked

- Multi-touch attribution (event tracking, custom & proprietary models)
- Real-time customer journey (marketing channels)
- P&L view & tracking (customizable cost buckets)
- RoAS tracking (integrates with Meta and Google Ads)
