# List card Custom Field values

> List typed Custom Field values stored on a Trello card.

`trello.listCardCustomFieldValues` lists every populated Custom Field value on one card.

```ts automations/list-trello-card-custom-field-values.automation.ts theme={null}
import { automation, onDashboardRun } from "automate.ax"
import { trello } from "automate.ax/trello"

export default automation("List Trello card Custom Field values", () => {
  onDashboardRun({ title: "List Trello card Custom Field values" })
  trello.listCardCustomFieldValues({ card: "card-id" })
})
```

Provide `card` as an ID, short link, or standard card URL. Optional second argument `{ account }` selects a Trello binding.

Returns `Signal<TrelloCustomFieldItem[]>`. Each item includes `id`, `cardId`, `customFieldId`, and a `value` discriminated by `type`: checkbox `checked`, date `date`, list `optionId`, number `number`, or text `text`.
