TikTok learns fastest from the whole journey.
The free channel app connects your store to TikTok. PixelRelay adds the measurement layer: the complete funnel relayed server-side to TikTok Events and to every other platform you run, with ttclid captured first-party and a per-order record of what actually arrived.
Keep the channel for the shop and in-feed placements. This is about the signal.
Short-form traffic browses far more than it buys.
On TikTok the gap between a view and a purchase is wide, which makes the middle of the funnel unusually valuable: add-to-carts and checkout starts are often the only volume a campaign has to optimise on before purchases accumulate.
PixelRelay relays the whole set server-side in TikTok's own event vocabulary, so optimisation and audience building read from the same complete record your other platforms get.
One authoritative path in. One event spec out.
Order capture is server-to-server: Shopify hands the order straight to our server, so there is no browser script on that path for anything to strip. A first-party script rides alongside it — served from your own store's domain, never a third-party one — purely to attach the ad-click receipts that earn your campaigns credit.
From there it's one set of rules fanned out to every destination you've connected — GA4, Meta, Google Ads, TikTok, Klaviyo, Bing, Reddit, Snapchat, Pinterest, LinkedIn and Segment, plus your own server endpoints. Change a rule once and every platform gets the change. No GTM container, no theme edits, and no digital fingerprinting — first-party signals only.
Each platform gets the proof of click it recognises.
A shopper can touch three platforms before they buy. PixelRelay captures every one of those ad-click receipts on a single first-party cookie, then hands each destination the parameter it understands — so the same order can be credited correctly everywhere, and you keep one owned record of the overlap.
Know it arrived. Know when it didn’t.
Most tracking setups give you a number in a platform dashboard. The number you actually need is which orders are behind it — and which ones aren’t.
Per-order reconciliation
Live delivery status for every order, per platform, checkable against your Shopify admin — with the reason when one didn’t relay: duplicate, stale order, quota, relay disabled.
Retries that surface
Failed sends are retried automatically, capped, and surfaced in your dashboard if they still can’t be delivered — so a failure becomes a task, not a silence.
Counted once
PixelRelay recognises sales an existing sender already reported and doesn’t send them again. One order stays one conversion, in every dashboard.
Breakage alerts
Threshold-based, not hopeful: events quiet for four hours, or delivery under 80% across a day, and you hear about it — instead of finding out at month end.
Two senders, one pixel.
PixelRelay deduplicates against events another sender already reported. Where two senders can't be matched, the same order can be counted twice — worth settling before you scale a campaign on the number.
Two senders, no decision
A doubled conversion count makes a campaign look twice as efficient as it is — and budget follows that number.
One canonical source
Decide which sender owns conversions, and keep a per-order ledger you can reconcile against Shopify.
What we do — and how to check what you have.
We’re not going to tell you what another app does under the hood; we don’t run it and it changes. Here’s what PixelRelay does, and the question that settles each row for your own store.
| Capability | PixelRelay | Check in your own admin |
|---|---|---|
| Event coverage | Product views, add-to-carts, cart views, checkout starts and purchases — the whole funnel, relayed server-side | Open your platform’s event dashboard. Which of those five are arriving, and which are marked server-side? |
| Destinations | One install, one event spec, 11+ destinations — including ones with no free channel app | Count the tracking apps on your store. To change one rule, how many places do you change it? |
| Ad-click receipts | gclid, gbraid and wbraid for iOS, fbclid and ttclid — captured on one first-party cookie with a 365-day window | Pull a recent converting order. Can you see which ad click it came from, on every platform at once? |
| Per-order delivery | Live delivery status per order, per platform — with the reason when one didn’t relay | Name an order from yesterday that didn’t reach the platform. Can you? |
| Retries | Automatic and capped on failed sends, surfaced in your dashboard if they still can’t be delivered | When a send fails today, where does that appear? |
| Breakage alerts | Threshold-based — events quiet 4h, or delivery under 80% over 24h | If tracking broke this morning, what would tell you, and how long would it take? |
| Counted once | Recognises sales an existing sender already reported, so one order stays one conversion | If you add a second sender to this dataset, what stops the same sale counting twice? |
| Conversion value | Adjusted for excluded products — gift cards, shipping protection — so you bid on revenue you actually want | Does the value you optimise against include line items you’d rather not bid on? |
| Subscriptions | Recharge subscription starts and renewals relay as conversions | Do renewals show up as conversions in your reporting today? |
| Headless | Works on Hydrogen and headless storefronts | If you moved off the Online Store theme tomorrow, what would still be tracking? |
The right-hand column is deliberately a question, not our description of another app. We don’t run it, and it changes.
When the free app on its own is enough.
Testing TikTok with a small budget, no other platforms in play, nobody reconciling anything? The free channel app on its own will tell you whether the channel works for you. That’s the question at that stage.
It stops being enough once TikTok is one of several platforms all claiming the same orders, or once you need the middle of the funnel to feed optimisation and audiences rather than just counting the sales that already happened.
