The timeline column contains a range of dates. This is useful should your item(s) require more than a single date to be stored.

Check out our help center to learn more about the column: The Timeline Column.

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

JSON

To update a timeline column, send the start and end dates in a YYYY-MM-DD format, where the start date is “from” and the end date is “to”.

For example: "{"from":"2019-06-03","to":"2019-06-07"}".

Code example

mutation {
  change_multiple_column_values(item_id:11111, board_id:22222, column_values: "{\"timeline_2\" : {\"from\" : \"2019-06-03\", \"to\" : \"2019-06-07\"}}") {
    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: YOUR_BOARD_ID,
      myItemId: YOUR_ITEM_ID,
      myColumnValues: "{\"timeline_2\" : {\"from\" : \"2019-06-03\", \"to\": \"2019-06-07\"}}"
    })
  })
})
