The request
“We were cleaning up the site and removing old apps and started noticing pixel failures. Product IDs don't match the catalog and events are inconsistent. Your team has always kept us running so I'm hoping you can sort this.”
App removal had disturbed the tracking setup. Ads were misattributing and the catalog was out of sync.
The approach
We reinstalled the Meta pixel cleanly, matched product IDs to the catalog feed, and verified each standard event fired once with correct parameters. Deduplication was set up so browser and server events didn't double-count.
