Why can't I use mirror columns in monday.com's native automations?

Mirror columns are read-only reflections of data from connected boards. monday.com's automation builder does not recognise them as selectable columns — you cannot choose them as triggers, conditions, or action targets. This trigger fills that gap.

Does the trigger fire for every type of mirror column change?

Yes. Whether the mirrored value is a status, number, text, date, or person — any change in the reflected value fires the trigger.

What happens if the source item on the connected board is deleted?

If the connected item is removed, the mirror column goes blank. This counts as a change, so the trigger will fire — you can use that to set up cleanup automations when linked items are deleted.

Trigger

Mirror Column Change Trigger

“When a mirror column's reflected value changes”

Fire an automation whenever a mirrored value updates. Mirror columns are invisible to monday.com's native automation builder — this trigger makes them actionable.

Use Cases

Notify account managers instantly when a mirrored customer tier changes on the CRM board

Change a local status when a mirrored project phase updates on the master board

Trigger a workflow when a mirrored deadline date shifts on a connected board

Real-World Example

Your team board mirrors a 'Priority' status from the master project board. When the project lead upgrades priority from 'Normal' to 'Urgent' on the master board, the mirrored value changes on your board and this trigger fires — instantly notifying your team and moving the item to the 'Urgent' group without anyone switching boards.
