Dependency

Learn how to filter, read, update, and clear the dependency column on monday boards using the platform API

The dependency column allows you to set up connections between items in the same board. They can then be visually represented in the Gantt View or Widget, or combined with automations. You can filter, read, update, and clear the dependency column via the API.

Filter the dependency 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 dependency column's supported operators and compare values.

OperatorsCompare values
any_ofThe item IDs to filter by
not_any_ofThe item IDs to filter by
is_emptynull
is_not_emptynull

Examples

The following example returns all items on the specified board that are dependent on item 9876543210.

query {
  boards (ids: 1234567890) {
    items_page (query_params: {rules: [{column_id: "dependent_on", compare_value: [9876543210], operator:any_of}]}) {
      items {
        id
        name
      }
    }
  }
}

Read the dependency column

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

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

Fields

FieldDescription
column Column!The column the value belongs to.
display_value String!The names of the dependent items, separated by commas.
id ID!The column's unique identifier.
linked_item_ids ID!The unique identifiers of the linked items.
linked_items [Item!]!The linked items.
text StringThe column's value as text. This field will always return null. Use display_value instead.
type ColumnType!The column's type.
updated_at DateThe column's last updated date.
value JSONThe column's JSON-formatted raw value.

Update the dependency column

You can update a dependency 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 add a dependent-on item to the dependency column, send the item IDs as an array. You will get an error if the items do not belong to the connected board. 

mutation {
  change_multiple_column_values (item_id:9876543210, board_id:1234567890, column_values: "{\"dependency\" : {\"item_ids\" : [\"11223344\", \"44332211\"]}}") {
    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: "{\"dependency\" : {\"item_ids\" : [\"11223344\", \"44332211\"]}}
    })
  })
})

Clear the dependency column

You can also clear a dependency column using the change_multiple_column_values mutation and passing null or an empty object in the column_values argument. 

mutation {
 change_multiple_column_values(item_id:9876543210, board_id:1234567890, column_values: "{\"dependent_on\" : 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: "{\"dependent_on\" : null}"
    })
  })
})
