Create Subitem

Create a subitem nested under an existing item. Use when the row belongs to a parent item; use Create Item for a top-level row. Set Board ID (the parent item's board), Parent Item ID and Item Name. Gotcha: subitems live on a separate subitems board, so Column Values must use that board's column IDs — run List Columns against the subitems board, not the board selected here. Example: Item Name Draft copy, Column Values { "status": "Done" }. Returns the new subitem's ID as a string. See the documentation

IMPLEMENTATION

Call this tool

Connect a user's monday account once, then configure and run Create Subitem from your backend or agent.

import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "monday-create-subitem",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    monday: { authProvisionId: "apn_xxxxxxx" },
    boardId: "Board ID",
    parentItemId: "Item ID",
  },
})

console.log(result)

Inputs

Pipedream supplies the connected account. Your application provides the operation-specific values below. Dynamic inputs are resolved against that user's account.

Create Subitem inputs
Property Type Description
boardId Board ID string
The board to act on, as a board ID (e.g. 2419687965). Use List Board ID Options to look up a board ID by name.
Required Dynamic
parentItemId Item ID string
Select a parent item or provide an item ID
Required Dynamic
itemName Item Name string
The new subitem's name
Required
columnValues Column Values object
The subitem column values to set, as column ID → value pairs. Example: { "status": "Done", "date4": "2026-09-02" }. These are the columns of the parent item's subitems board, which is a separate board from the one selected above — run List Columns against that subitems board to discover its column IDs. See the Column types reference for the value each column type expects
Optional
