Apparently, Facebook detected Credit Card data that appeared as "pr_rec_pid" coming from PageView events in the URL Query Parameter. Facebook says I need to update those URL's query parameters and to look where the specific parameter is shown to get it removed and solve the problem. They also explained that Credit Card data should never be sent to Facebook, so obviously I need to remove this data from those website URL's to help prevent this from occurring but I have no idea how to do it.
Since it says this issue may impact the performance of any ads optimizing on affected events, including those used in Custom Audiences or custom conversions, it is a big concern for my business.
I appreciate your help!
Solved! Go to the solution
I tried everything that I found on shopify support but the I still have the issue showing in violations. What's frustrating is that the URL'S with the issue are for FACEBOOK catalog products from IG. So if someone clicks on a product from our IG shop, and then clicks on the URL, this click will show up on the pixel diagnostic as a violation/potential issue. All the URL's affected end up with the below. I have contacted FB and Shopify and both don't know how to fix this. still looking for a solution.
