> Cancel a payment transaction that is still pending.

Canonical: https://docs.chiwapay.com/payment-cancel

`POST /payments/:id/cancel`

Cancel a transaction that is still `pending`.
The ShopeePay Partner SDK does not support cancellation.
When the request succeeds, the transaction status changes to `cancelled` and a `payment.cancelled` event is sent to webhooks.

The `POST /transactions/:id/cancel` alias is available with the same behavior.

## Status Rules

| `pending` | `cancelled` |
| `refund_processing` | `paid`, the refund process is cancelled. |
| `created`, `paid`, `expired`, `failed`, `cancelled`, `settled`, `refund_failed`, `refunded` | Cannot be cancelled. |

## Path Params

| Param | Type | Required | Description |
| --- | --- | --- | --- |
