PrestaShop server-side tracking module
Install the datafirefly_serverside module on your PrestaShop store and send the purchase conversion server-side, directly to Meta Conversions API (CAPI), GA4, TikTok, Pinterest and Microsoft Advertising. Per-shop HMAC signing, fail-safe by design so a tracking error never breaks checkout, and GDPR consent gating. A single connection key, no pixel IDs to paste into PrestaShop.
The module installs from a ZIP uploaded in the module manager, no FTP access required.
Your PrestaShop browser tags are leaking sales
The Meta pixel, GA4 tag, or TikTok tag in your PrestaShop theme runs in the customer's browser: where it's increasingly blocked before it even gets to fire.
-
Ad-blockers
stop the tags from loading on the order confirmation page: the purchase is never reported to your platforms.
-
Safari ITP
and similar protections shorten or remove the cookies your conversion tags depend on.
-
Cookie restrictions and consent friction
further reduce what browser-side tracking can capture at the moment of purchase.
The result: incomplete PrestaShop conversions, degraded match quality, and campaigns optimising on a partial view. You're paying for sales you can't fully measure.
The PrestaShop purchase conversion, sent server-side
The datafirefly_serverside module captures the purchase on the actionValidateOrder hook, the moment the order is validated server-side, and sends it server-to-server, directly to each platform's conversion API (CAPI): the channel built for reliable, first-party conversion data.
Recovered purchases
The purchase conversion no longer depends on browser tags surviving ad-blockers and ITP, so you recover sales that would otherwise be lost.
Better match quality
The module captures the available browser identifiers (_fbp,
_fbc, _ttp, GA clientId) for a
richer, more reliable match signal.
Zero risk to checkout
Fail-safe by design: tight timeouts and full exception handling. A tracking error is logged but never interrupts the order.
Three steps to complete purchase tracking
Install the PrestaShop module
Upload datafirefly_serverside-1.0.1.zip in Modules → Module Manager. PrestaShop registers the actionValidateOrder hook automatically.
Paste your connection key
Enter your Tenant ID and HMAC secret, copied from "Connect your shop" in your DataFirefly account (/app). No pixel IDs to enter.
The purchase goes out server-side
On every validated order, the purchase event is HMAC-signed and delivered to the dispatcher, which fans it out to all your configured destinations. One install, every platform.

Server-side purchase conversion
Sends the purchase event on order validation (actionValidateOrder hook), directly to the conversion APIs.
HMAC-SHA256 signing
Every request is signed per shop (X-Dfss-Tenant, X-Dfss-Timestamp, X-Dfss-Signature headers). Destination credentials never touch the browser.
Fail-safe by design
Tight HTTP timeouts and full exception handling: a tracking error never breaks checkout. Failures are logged.
Consent gating
With "Require consent", the purchase is only sent if the customer consented to an advertising service: read server-side from the tarteaucitron / DataFirefly Cookie Manager cookie.
Richer match quality
Captures the available browser identifiers (_fbp, _fbc, _ttp, GA clientId) alongside order and customer data.
"Send test event" button
Verify connectivity and the signature from the configuration screen, before even placing a real test order.
.htaccess-protected source
The module ships with an .htaccess that denies direct web access to the module's source files.
EU-hosted
The dispatcher runs in Germany: your data stays in the EU.
Meta CAPI, GA4, TikTok, Pinterest and Microsoft Advertising from PrestaShop

Conversions API
Google Ads (Data Manager API) is available at the platform level. The PrestaShop module 1.0.1 delivers the purchase to Meta CAPI, GA4, TikTok, Pinterest and Microsoft Advertising.
Install the server-side module on PrestaShop
Requirements: PrestaShop 1.7.6.0 or newer, a DataFirefly server-side account, and outbound HTTPS access to serverside.datafirefly.com.
Get your connection key
In "Connect your shop" in your DataFirefly account (/app), copy your Tenant ID (e.g. shop_yourstore_xxxx) and your HMAC secret (64-character key). The endpoint is pre-filled to https://serverside.datafirefly.com/v1/events.
Upload the ZIP in the Back Office
Modules → Module Manager → Upload a module, then select datafirefly_serverside-1.0.1.zip (do not unzip). PrestaShop installs it and registers the actionValidateOrder hook automatically.
Configure the module
Click Configure. Enter Tenant ID, HMAC secret, leave the endpoint at its default, set Require consent to Yes (recommended for GDPR), then switch Enable tracking to Yes and save.
Verify the connection
Click Send test event: a success message confirms Tenant ID, HMAC secret and endpoint. Then place a real test order and open the Inspector in /app to confirm the purchase event arrives (value, currency, reference).
Delivery errors are logged under Advanced Parameters →
Logs (entries prefixed [DataFirefly SS]). A tracking
failure is logged but never interrupts the order.

Frequently asked questions: PrestaShop module
What is the server-side tracking module for PrestaShop?
The datafirefly_serverside module (version 1.0.1, compatible with PrestaShop 1.7.6 and up) sends your store's purchase conversion server-to-server, directly to each platform's conversion API (Meta CAPI, GA4, TikTok, Pinterest, Microsoft Advertising). The purchase event fires when the order is validated and is HMAC-signed for your shop. Destination credentials never pass through the browser.
Can the module break my PrestaShop checkout?
No. The module is fail-safe by design: tight HTTP timeouts and full
exception handling mean a tracking error can never interrupt the order
or the checkout. A failed delivery is logged (prefixed
[DataFirefly SS] in the PrestaShop logs) but the order
always completes normally.
Do I have to paste pixel IDs into PrestaShop?
No. You only enter your Tenant ID and HMAC secret, copied from the "Connect your shop" screen in your DataFirefly account (/app). The dispatcher knows which destinations to fan out to. You never paste a pixel ID or access token into the store.
Does the module respect GDPR consent?
Yes. With Require consent enabled, the purchase is only sent if the buyer has consented to an advertising service, read server-side from the tarteaucitron / DataFirefly Cookie Manager cookie. The dispatcher is EU-hosted (Germany) and personal data is redacted.
Do I need to host a server-side GTM container?
No. DataFirefly sends events directly to each platform's conversion API: there's no server-side GTM container to host or maintain. Setup is limited to the PrestaShop module and a single connection key.
