My Facebook CAPI Sent Wrong Events for 3 Months

Here is a story I wish I did not have to tell.

I now check religiously. Shopify froze and it confused customers. What I learned: most merchants do not know this happens.

How to Prevent This

Eventually I found a workaround and things went back to normal. The most avoidable part? It had been broken for weeks. What I learned: testing your own store is the only safety net.

• What I learned: testing your own store is the only safety net.
• What bothers me is there was no warning.

• Turns out the setting was the culprit.
• I audit religiously.

The reality: testing your own store is the only safety net.

The Fix

I audit before any launch. Eventually I uninstalled the app and everything worked again.

Shopify crashed and it wasted hours. Eventually I reverted the change and things went back to normal. I review religiously.

I now check every day. Turns out the API call was corrupted. Here is the thing: you only find out when revenue drops.

3. Eventually I patched it manually and the problem was resolved.
⚠️ Warning: I spent the whole weekend trying to figure out what was happening.

I hope this saves someone else the money and headache. Check your settings. Test your checkout. Audit your apps. The platform will not do it for you.
