How do I fix a Meta Pixel that is firing purchase events on the wrong thank-you URL?

This misfire happens when your custom conversion rules rely on overly broad page-view triggers (like /thank-you) that accidentally execute when a user refreshes their receipt or views older order details.

“This tends to crop up when your conversion trigger is set too broadly, so it fires again every time someone refreshes an old receipt. I’ll tighten the trigger and have it accurate within 24 hours for $99.”
