Dependency
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. Our API fully supports the dependency column, so you can filter, read, update, and clear it via the API.
Filtering 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.
Operators | Compare values |
---|---|
any_of | The item IDs to filter by |
not_any_of | The item IDs to filter by |
is_empty | null |
is_not_empty | null |
Pro tip
items_page
is only available in API version2023-10
for now.
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
}
}
}
}
Reading the dependency column
You can query the dependency 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 dependency column are of the DependencyValue
type.
Pro tip
column_values
v2 fields are only available in API version2023-10
.
query {
items (ids:[1234567890, 9876543210]) {
column_values {
... on DependencyValue {
linked_item_ids
updated_at
}
}
}
}
Fields
Field | Description |
---|---|
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 String | The column's value as text. Please note: this field will return no data in API version 2023-10 . Use display_value instead. |
type ColumnType! | The column's type. |
updated_at Date | The column's last updated date. |
value JSON | The column's JSON-formatted raw value. |
Column values v1
You can only return the data in a dependency column in one format when you query by column values. The text
field will return an empty result. The value
field will return metadata about the dependent-on items as a JSON string.
Removing column values v1 support
column_values
v1 fields will no longer be supported in API versions2023-10
and later.
{
"text": "",
"value": "{\"linkedPulseIds\":[{\"linkedPulseId\":2973227079}]}"
}
Updating 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: "{\"dependent_on\" : {\"item_ids\" : [0987654321]}}") {
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: $myColumnValues) { id } }",
'variables' : JSON.stringify({
myBoardId: 1234567890,
myItemId: 9876543210,
myColumnValues: "{\"dependent_on\" : {\"item_ids\" : [0987654321]}}
})
})
})
Clearing the dependency column
You can also clear a dependency column using the change_multiple_column_values
mutation and passing null
or an empty object in the column_values
argument. Check out this mutation in action in our Postman library or follow along with these code samples!
mutation {
change_multiple_column_values(item_id:9876543210, board_id:1234567890, column_values: "{\"dependent_on\" : null}") {
id
}
}
fetch ("https://api.monday.com/v2", {
method: 'post',
headers: {
'Content-Type': 'application/json',
'Authorization' : 'YOUR_API_KEY_HERE'
},
body: JSON.stringify({
query : "mutation ($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}"
})
})
})
