  %Stripe.Params.BillingPortal.ConfigurationUpdateParams.Features.SubscriptionCancel{
    cancellation_reason:
      Stripe.Params.BillingPortal.ConfigurationUpdateParams.Features.SubscriptionCancel.CancellationReason.t()
      | nil,
    enabled: boolean() | nil,
    mode: String.t() | nil,
    proration_behavior: String.t() | nil
  }
```

* `cancellation_reason` - Whether the cancellation reasons will be collected in the portal and which options are exposed to the customer
* `enabled` - Whether the feature is enabled.
* `mode` - Whether to cancel subscriptions immediately or at the end of the billing period. Possible values: `at_period_end`, `immediately`.
* `proration_behavior` - Whether to create prorations when canceling subscriptions. Possible values are `none` and `create_prorations`, which is only compatible with `mode=immediately`.

Possible values: `always_invoice`, `create_prorations`, `none`.
