Question: How can I address the deduplication of events with Facebook?
Unfortunately, We cannot assist with editing or adding of the parameter needed, as this is beyond our support scope. If you are not familiar with doing this, I would recommend reaching out to Facebook to see how they can assist you in eliminating the duplicate events by assisting with adding the parameter.
Facebook also has a handy article on deduplication here: https://developers.facebook.com/docs/marketing-api/conversions-api/deduplicate-pixel-and-server-events/
