Hi, I want to create a custom app that will trigger when a mirror column changes, then my custom action is to send a webhook with the whole payload,
The only issue I face is when I’m selecting the native trigger “when a column changes”, it doesn’t show me the mirror columns in the dropdown, why is that?
Mirror columns are not supported as triggers for most automations, and definitely not with apps. The only automations that support mirrors as triggers are a handful of built-in automation templates you can find in the automation center under the “mirror” category.
There are possible workarounds developers have created, but I would not expect them to divulge their proprietary work, so likely you’ll need to figure out how to work around it yourself.
