# Create checklist

> Create or copy a checklist on a Trello card.

`createChecklist` creates an empty checklist or copies an existing checklist and its items.

```ts automations/create-trello-checklist.automation.ts theme={null}
import { automation, onHttpRequest } from "automate.ax"
import { createChecklist } from "automate.ax/trello"

export default automation("Create Trello checklist", () => {
  onHttpRequest({ scope: "automation" })
  createChecklist({ card: "card-id", name: "Launch", position: "bottom" })
})
```

`card` is required. `name` and `sourceChecklistId` are optional; `position` accepts `"top"`, `"bottom"`, or a nonnegative number and defaults to `"bottom"`; optional `account` defaults to the project binding. When copying, Trello controls how `name` interacts with the source name.

Returns the created `TrelloChecklist`, including any copied `checkItems` supplied by Trello.
