```ts automations/highlevel-cancel-scheduled-message.automation.ts theme={null}
import { automation, markSignificant } from "automate.ax"
import { highlevel } from "automate.ax/highlevel"

export default automation("Cancel scheduled message", () => {

## Input

Automate.ax supplies the connected sub-account's location ID. Optional second argument `{ account }` selects a named HighLevel binding.

## Output

| `status`  | `number` | Yes      | HTTP Status code of the request |

This action calls `DELETE /conversations/messages/{messageId}/schedule` with HighLevel API version `2021-04-15` and requires `conversations/message.write`. HighLevel validation and permission errors fail the action. Rate limits honor the provider's retry timing.
