# Delete Column

`DELETE /studio/v1/audiences/{audienceId}/columns/{columnId}`

Permanently removes a specific column from an audience, including all cell values stored in that column across every row.

This action is irreversible — all data in the deleted column cannot be recovered.
Returns `204 No Content` on successful deletion.
Returns `400` if the column is not deletable.
Returns `404` if the `audienceId` or `columnId` does not exist.
