Can I use Facebook pixel with my third-party tracking provider to track conversions?
Yes, you can use Facebook pixel with your third-party tracking provider (e.g. DoubleClick). The Facebook pixel can piggyback and fire off of the existing pixel implementations without requiring you to edit the HTML on your website, if that feature is available from your third-party provider.
In most cases, you need to copy the content of the HTML tag inside the
DFA tags
You can piggyback your Facebook pixel off DFA tags by copying and pasting only the URL portion of the Facebook pixel. Bear in mind that this isn't the entire JavaScript code. This is the portion of code that your copy should mirror:
Check that the URL includes "https" to ensure that you're using secure tags.
Secure:
Non-secure:
You should also use the Default tag rather than Publisher tag so that you don't miss any cross-device conversions.
