Facebook Pixel: Consent and cookies

How the Facebook Pixel plugin for Shopware 6.7 handles consent: Klaro integration, recognised consent cookies, behaviour without consent and the Klaro service that is created on activation.

Facebook Pixel: Consent and cookies

Live Demo: Try this and other plugins live — no installation, no risk: demo.markus-michalski.net

The plugin has three operating modes. Which one applies depends on two settings. The same rule applies to the browser and to the Conversions API.

Mode Settings Pixel in the browser Conversions API
No consent check Klaro off, Require Cookie Consent off Loads immediately on every page Sends immediately
Own cookie check Klaro off, Require Cookie Consent on Only with a recognised consent cookie, otherwise nothing is output Only with a recognised consent cookie
Klaro Use Klaro Consent Manager on Scripts are delivered blocked and released by Klaro Only if the Klaro cookie contains consent for the service

Privacy: The mode "No consent check" is the default: The pixel loads without consent, and Meta receives data from the first page view on. For visitors in the EU, choose one of the other two modes.

With Require Cookie Consent, the server checks whether consent exists while rendering the page. Without consent, the plugin outputs no pixel script. The check runs server-side on every page request, so consent given takes effect from the next page that is loaded.

Consent is assumed when one of the following conditions is met:

Cookie Counts as consent when
fb_consent the value is 1, true, yes, accepted or allow
CookieConsent the value is 1, true, yes, accepted or allow
CookieControl the value is 1, true, yes, accepted or allow
cookie-agreed the value is 1, true, yes, accepted or allow
cookie-preference the content is a JSON object with "marketing": true

Upper and lower case and whitespace around the values do not matter. All other values, including false or maybe, count as no consent. If your consent solution sets none of these cookies, you can configure it to set fb_consent=1.

Klaro integration

The prerequisite is the MmdKlaroConsent plugin.

  1. Install and configure the MmdKlaroConsent plugin
  2. Activate Facebook Pixel, which creates the Klaro service (see below)
  3. Switch on Use Klaro Consent Manager in the configuration
  4. Check the Klaro Service Name. It has to match the service in MmdKlaroConsent (default facebook-pixel).

With the Klaro integration active, the plugin outputs the pixel script as <script type="text/plain" data-type="text/javascript" data-name="...">, with the service name in the data-name attribute. Klaro runs the script only after consent. This applies to the base code including PageView and to all event scripts.

For the Conversions API, the plugin reads the klaro cookie on the server. It must be a JSON object in which the service name has the value true. If the cookie or the entry is missing, the Conversions API sends nothing.

With the Klaro integration active, Require Cookie Consent is not evaluated. Only Klaro and the klaro cookie decide.

Privacy: The fallback for browsers without JavaScript (the noscript image from facebook.com) is also output in Klaro mode. Without JavaScript, Klaro cannot ask for consent, so such a browser requests the image without consent.

The Klaro service

On activation of the plugin and in its migration, the plugin creates a cookie service, provided the MmdKlaroConsent table exists and no service with the technical name facebook-pixel exists yet. If MmdKlaroConsent was installed after Facebook Pixel, the service is created when you activate the plugin again.

Property Value
Technical name facebook-pixel
Purpose marketing
Required / enabled by default no / no
Cookies _fbp, _fbc (path /) and fr (domain .facebook.com)
Position 20
Assignment all storefront sales channels
Title Facebook Pixel (DE and EN)
Description DE Ermöglicht die Messung und Optimierung von Facebook-Werbekampagnen. Facebook sammelt Daten über Ihre Interaktion mit unserer Website.
Description EN Enables measurement and optimization of Facebook advertising campaigns. Facebook collects data about your interaction with our website.

The automatically created service is always named facebook-pixel. If you change the Klaro Service Name setting, you have to create a service with the new name in MmdKlaroConsent yourself.

Cookies from Meta

The plugin itself sets no cookies. The Meta script creates the cookies _fbp and _fbc in the browser, among others. The Conversions API reads them when present and passes them on to Meta to match events, see Privacy.
