The checkbox column represents a simple true or false value on a board. Our API supports this column, so you can read and update the checkbox column via the API.

Reading the checkbox column

You can return the data in a checkbox column in two different formats. The text field will return the data as a simple string, and the value field will return the data as a JSON string.

{
  "text": "v",
  "value": "{\"checked\":\"true\",\"changed_at\":\"2022-07-14T12:00:00.000Z\"}"
}

Updating the checkbox column

JSON

You can update a checkbox column with a JSON string. Simple string updates are not supported.

To check the box in the checkbox column, send: {"checked" : "true"}

mutation {
  change_multiple_column_values(item_id: 1234567890, board_id: 1122334455, column_values: "{\"checkbox\" : {\"checked\" : \"true\"}}") {
    id
  }
}
fetch ("https://api.monday.com/v2", {
  method: 'post',
  headers: {
    'Content-Type': 'application/json',
    'Authorization' : 'YOUR_API_KEY'
  },
  body: JSON.stringify({
    query : "mutation ($myBoardId:Int!, $myItemId:Int!, $myColumnValues:JSON!) { change_multiple_column_values(item_id:$myItemId, board_id:$myBoardId, column_values: $myColumnValues) { id } }",
    variables : JSON.stringify({
      myBoardId: 162169280,
      myItemId: 162169283,
      myColumnValues: "{\"checkbox\" : {\"checked\" : \"true\"}}"
    })
  })
})

You can find the Postman request to check a checkbox here.

Clearing the checkbox column

You can clear the checkbox column with a change_multiple_column_values.

mutation {
  change_multiple_column_values(item_id: 2973227073, board_id: 2973227049, column_values: "{\"check\" : null}"){
    id
  }
}

You can also find the Postman request to uncheck a checkbox here.
