## Deletes or cancels (2)

### `recurly_cancel_customer_subscription`

- The name "recurly_cancel_customer_subscription" says "cancel": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Cancel a subscription. By default it stays active until the end of the current term (`term_end`); pass timeframe `bill_date` to cancel effective the next bill date. This changes billing state. Recurly: PUT /subscriptions/{subscription_id}/cancel.
```

### `recurly_pause_subscription`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Pause a subscription for a number of upcoming billing cycles. Set `remaining_pause_cycles` to 0 to resume/cancel an existing pause. This changes billing state. Recurly: PUT /subscriptions/{subscription_id}/pause.
