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/
Important Note: If you receive a duplication event error, you will need to use tools like cfpowerscripts or funnelish as they prevent the duplication and adds more parameters for you to manage your pixel events. Below is an example of how it identifies duplicate events and how they are managed. The screenshot was taken inside of cfpowerscripts. You can navigate to CF Power Scripts and choose from the different Facebook power scripts that have been created to help you manage your Facebook events more effectively.
