Facebook Pixel: Privacy

Which data the Facebook Pixel plugin for Shopware 6.7 transmits to Meta: browser pixel and Conversions API, what is hashed and what is not (IP address, user agent), and what to state in your privacy policy.

Facebook Pixel: Privacy

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

The plugin transmits data to Meta (Facebook). This page shows exactly what that data is. It is not legal advice.

Privacy: With the Conversions API, the visitor's IP address and user agent are not hashed. They are sent to Meta in plain text. Only the email address and phone number are hashed with SHA-256.

Browser pixel

What Where to When
Meta script fbevents.js is loaded connect.facebook.net As soon as the pixel is output (see Consent and cookies)
Pixel ID and event data (see Events and data) Meta, through the Meta script On every event
Image for browsers without JavaScript (noscript) www.facebook.com/tr with Pixel ID and ev=PageView On every page on which the pixel is output, also in Klaro mode

What the Meta script collects beyond that is determined by Meta. This includes what Meta learns from cookies, the IP address and the user agent of the browser.

Conversions API (server-side)

Only when the Conversions API is active and the event meets all conditions (see Conversions API). Data is sent to graph.facebook.com.

Field (user_data) Content Treatment
client_ip_address Visitor's IP address, falling back to 0.0.0.0 Not hashed
client_user_agent Browser user agent, truncated to 512 characters Not hashed
em Email address SHA-256, lowercased and trimmed beforehand
ph Phone number SHA-256, reduced to digits beforehand
fbc Value of the _fbc cookie, if present and in the expected format unchanged
fbp Value of the _fbp cookie, if present and in the expected format unchanged

In addition, event_source_url (full URL of the page, including the query string) and custom_data (the event data) are sent. The access token is in the request body.

Only the email address and phone number go through hashing. The IP address and user agent are deliberately sent unchanged, because Meta expects them that way.

When are email and phone number included?

Event Email Phone number
PageView, ViewContent, ViewCategory, AddToCart of the customer of the current session never
InitiateCheckout of the customer of the current session from the active billing address of that customer
Purchase of the orderer (also for guest orders) from the billing address of the order

"Customer of the current session" means: as soon as the Shopware session is assigned to a customer (customer account or guest customer with an active session), that customer's email address is sent along, hashed. Visitors without an assigned customer send neither email nor phone number, except on Purchase.

Temporary storage in the queue

Until the consumer processes the message, it sits in Shopware's message queue. The message contains the IP address, user agent, URL and the hashed values for email and phone number. Email address and phone number are never stored there in plain text.
