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

👍

Pro tip

items_page is only available in API version 2023-10 for now.

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. The object has different fields based on which API version you are using. Column values v2 fields will be available in API versions 2023-10 and later, while column values v1 fields are only supported in versions 2023-07 and 2023-04.

Column values v2

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

👍

Pro tip

column_values v2 fields are only available in API version 2023-10.

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.
type ColumnType!The column's type.
updated_at DateThe column's last updated date.
value JSONThe column's JSON-formatted raw value.

Column values v1

You can return the data in a checkbox column in two different formats when you query by column values. The text field will return the data as a simple string; the result will be empty if the column is unchecked. The value field will return metadata about the column as a JSON string.

🚧

Removing column values v1 support

column_values v1 fields will no longer be supported in API versions 2023-10 and later.

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

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: "{\"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: "{\"checkbox\" : null}"
    })
  })
})
