Server-Side Tracking for E-commerce, Without GTM Complexity
Send consented conversion events directly from PrestaShop, WooCommerce, Shopware, Shopify or your own application to Meta CAPI, GA4, Google Ads, TikTok, Pinterest and Microsoft Advertising.
DataFirefly gives you reliable, deduplicated server-side tracking through one lightweight integration, without requiring you to host or maintain a server-side GTM container.
What is server-side tracking?
Server-side tracking is a method of collecting and sending website or e-commerce events through a controlled server endpoint instead of relying exclusively on scripts running in the visitor's browser.
With traditional client-side tracking, browser restrictions, ad blockers and tracking prevention can stop analytics and advertising tags from loading. Server-side tracking creates a more reliable path for consented events such as product views, checkouts and purchases.
Server-side tracking without a GTM server container
Google Tag Manager server-side is one way to implement server-side tracking: often called server-side tagging, but it requires a server container, hosting, tags and ongoing maintenance. If those two terms sound interchangeable, our page on server-side tagging versus server-side tracking explains what an sGTM container really is and when it is the better choice.
DataFirefly uses a more direct approach. Your store sends signed events to the EU-hosted DataFirefly dispatcher, which delivers them directly to the conversion APIs you have configured. There is no GTM server container to create or maintain. See the detailed comparison.
Why e-commerce stores need server-side tracking
Conversion tracking has always run in the visitor's browser. That worked until the browser became the bottleneck.
-
Ad-blockers
stop tags from ever loading, so the conversion is never recorded.
-
Safari ITP
and similar protections shorten or remove the cookies your tags depend on.
-
Cookie restrictions and consent friction
further reduce what browser-side tracking can capture.
The result: incomplete conversion data, weaker ad match quality, and campaigns optimising on a partial view. You're paying for results you can't fully measure.
Server-side conversion tracking, straight to the source
DataFirefly moves tracking out of the fragile browser layer. Your events are sent server-to-server, directly to each platform's conversion API (CAPI): the channel ad and analytics platforms built specifically for reliable, first-party conversion data.
Recovered conversions
The signal no longer depends on browser tags surviving ad-blockers and ITP, so you recover conversions that would otherwise be lost.
Richer match quality
The data you do send carries richer, more reliable match quality: improving attribution and platform optimisation.
One integration
One integration on your site feeds every platform you've configured.

DataFirefly or server-side GTM hosting?
Stape, Addingwell and other sGTM hosts rent you the infrastructure of a Google Tag Manager container that you configure and maintain. DataFirefly removes the container: your events go straight to the conversion APIs.
| sGTM hosting (Stape, Addingwell…) | DataFirefly Server-Side | |
|---|---|---|
| GTM container | To create, configure and maintain | None, direct CAPI dispatch |
| Getting started | Tag setup by a GTM expert, site by site | Connector + connection key, in minutes |
| Maintenance | Tags and templates on your plate | API connectors maintained by DataFirefly |
| Multiple shops | One container (often one plan) per site | Every shop under one subscription |
| Skills required | Server-side GTM | None, the client area is all you need |

Frequently asked questions about server-side tracking
What is server-side tracking, and how is it different from my current tags?
Today your tags run in the visitor's browser, where ad-blockers, Safari ITP, and cookie restrictions can stop them. Server-side tracking sends your events from a server, directly to each platform's conversion API, so the data gets through even when browser tags would be blocked.
Is server-side tracking the same as server-side tagging?
Not exactly. Server-side tracking describes the overall method of sending events through a server. Server-side tagging usually refers to managing those events through a server-side tag-management container, such as Google Tag Manager server-side. DataFirefly performs server-side tracking through direct conversion API integrations, without requiring a GTM server container.
Does server-side tracking bypass ad blockers?
Server-side delivery reduces the number of conversions lost when client-side tags are blocked. It should not be used to bypass consent choices, and DataFirefly only sends events when the required consent is available.
Does server-side tracking work without cookies?
Server-side tracking reduces reliance on browser cookies, but cookies and browser identifiers may still be used for attribution, deduplication and event matching when consent is present. It is not completely cookieless tracking.
Will I record the same conversion twice?
No. DataFirefly performs client + server deduplication: browser and server events for the same action are matched and deduplicated, so conversions aren't double-counted.
Do I still need a consent banner?
Yes. Moving tracking to a server does not remove GDPR or consent obligations. DataFirefly integrates with consent-management systems and prevents events from being sent when the required consent has not been given.
Is this GDPR-compliant?
DataFirefly is GDPR-friendly by design. The dispatcher is EU-hosted in Germany, personal data is redacted (no raw PII is exposed), ingestion is HMAC-authenticated, and tracking is consent-aware: events fire only with the visitor's consent. DataFirefly's cookie-banner modules (WordPress, PrestaShop) implement Google Consent Mode v2 natively.
Which platforms can I send events to?
Six destinations: Meta Conversions API, GA4 Measurement Protocol, TikTok Events API, Pinterest Conversions API, Google Ads (Data Manager API), and Microsoft Advertising (Conversions API). You configure once and deliver to all of them server-side.
What do I need to install?
A lightweight connector: a PrestaShop module, a WooCommerce plugin or a Shopware plugin. On Shopify, connect your webhooks in minutes from your client area. On any other platform, our signed HTTP API works on any site.
Do I need to host a server-side GTM container?
No. DataFirefly sends events directly to each platform's conversion API, so there's no server-side GTM container to host or maintain. That's what makes it simpler to set up and cheaper to run.
Can I see what's actually being sent?
Yes. The Event Inspector lets you review events one by one to verify what's being delivered. It's GDPR-safe: personal data is redacted.
Can one account cover several sites?
Yes. One subscription covers all the sites on your account, billed on a single consolidated invoice. Higher tiers include more sites and more monthly events.
