The checkbox column represents a simple true or false value on a board. You can filter, read, update, and clear the checkbox column via the API.

Filtering the checkbox column

Using the items_page object, you can easily filter a board's items by specific columns or column values. The table below contains the checkbox column's supported operators and compare values.

OperatorsCompare values
is_emptynull
is_not_emptynull

Examples

The following example returns all items on the specified board that have an unchecked checkbox column.

query {
  boards (ids: 1234567890) {
    items_page (query_params: {rules: [{column_id: "check", compare_value: [null], operator:is_empty}]}) {
      items {
        id
        name
      }
    }
  }
}

Reading the checkbox column

You can query the checkbox column using the column_values object that enables you to return column-specific subfields by sending a fragment in your query. Values for the checkbox column are of the CheckboxValue type.

query {
  items (ids:[1234567890, 9876543210]) {
    column_values {
      ... on CheckboxValue {
        checked
        updated_at
      }
    }
  }
}

Fields

FieldDescription
checked BooleanReturns true if the column is checked.
column Column!The column the value belongs to.
id ID!The column's unique identifier.
text StringThe column's value as text. This field will return "" if the column has an empty value.
type ColumnType!The column's type.
updated_at DateThe column's last updated date.
value JSONThe column's JSON-formatted raw value.

Updating the checkbox column

You can update a checkbox column using the change_multiple_column_values mutation and passing a JSON string in the column_values argument. Simple string updates are not supported.

JSON

To check the box, send {"checked" : "true"} in the column_values argument. Check out this mutation in action in our Postman library or follow along with these code samples!

mutation {
  change_multiple_column_values(item_id:1234567890, board_id:9876543210, column_values: "{\"checkbox\" : {\"checked\" : \"true\"}}") {
    id
  }
}
fetch ("https://api.monday.com/v2", {
  method: 'post',
  headers: {
    'Content-Type': 'application/json',
    'Authorization' : 'YOUR_API_KEY_HERE'
  },
  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: 1234567890,
      myItemId: 9876543210,
      myColumnValues: JSON.stringify({ checkbox: { checked: "true" }})
    })
  })
})

Clearing the checkbox column

You can also clear (uncheck) a checkbox column using the change_multiple_column_values mutation and passing null in the column_values argument. Check out this mutation in action in our Postman library or follow along with these code samples!

mutation {
  change_multiple_column_values(item_id:9876543210, board_id:1234567890, column_values: "{\"checkbox\" : null}"){
    id
  }
}
fetch ("https://api.monday.com/v2", {
  method: 'post',
  headers: {
    'Content-Type': 'application/json',
    'Authorization' : 'YOUR_API_KEY_HERE'
  },
  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: 1234567890,
      myItemId: 9876543210,
      myColumnValues: JSON.stringify({ checkbox: { null }})
    })
  })
})
