The mirror column shows a column value from another board through a linked item. This column is partially supported by our API, so you can read the mirror column via the API but cannot update it.

Reading the mirror column

You can return the data in a mirror column in just one format. The text field will return the data as a simple string that displays the data from the other board. The value field will always return null.

  "value": null,
  "text": "Working on it"

You can also query the source board directly to return the necessary fields. To update the mirror column, directly update the column value on the source board.
