Create Custom Field

trello.createCustomField creates a Custom Field definition on one board. The board must belong to a Standard, Premium, or Enterprise Workspace. Free Workspaces return Trello’s 403 Custom Fields Power-Up disabled for board response; see Authorization and raw API.

automations/create-trello-custom-field.automation.ts

import { automation, onDashboardRun } from "automate.ax"
import { trello } from "automate.ax/trello"

export default automation("Create Trello Custom Field", () => {
  onDashboardRun({ title: "Create Trello Custom Field" })
  trello.createCustomField({
    board: "board-id",
    displayOnCardFront: true,
    name: "Estimate",
    position: "bottom",
    type: "number",
  })
})

Provide board, non-empty name, and type as "checkbox", "date", "list", "number", or "text". displayOnCardFront defaults to true. position accepts "top", "bottom", or a nonnegative number and defaults to "bottom". Optional second argument { account } selects a Trello binding. Returns the created TrelloCustomField. Add dropdown choices separately with trello.createCustomFieldOption when type is "list".
