# Verify sending domains

{% hint style="info" %}
🦄**Protecting your data:** Verifying sending domain is a way for Facebook to know that you have permission to send conversion data from the site to the pixel. \
\
If they don't have this, imagine how everyone would be able to **send malicious data** to your pixel, messing up your pixel altogether!
