# Resume a subscription

Initiates resumption of a paused subscription, optionally resetting the billing cycle anchor and creating prorations. If no resumption invoice is generated, the subscription becomes `active` immediately. If a resumption invoice is generated, the subscription remains `paused` until the invoice is paid or marked uncollectible. If the invoice is not paid by the expiration date, it is voided and the subscription remains `paused`.

## Returns

The subscription object.

## Parameters

- `billing_cycle_anchor` (enum, optional)
  The billing cycle anchor that applies when the subscription is resumed. Either `now` or `unchanged`. The default is `now`. For more information, see the billing cycle [documentation](https://docs.stripe.com/docs/billing/subscriptions/billing-cycle.md).
Possible enum values:
  - `now`
    Reset the subscription’s billing cycle anchor to the current time (in UTC) and start a new billing period.

  - `unchanged`
    Advance the subscription to the period that surrounds the current time without resetting the billing cycle anchor.

- `proration_behavior` (enum, optional)
  Determines how to handle [prorations](https://docs.stripe.com/docs/billing/subscriptions/prorations.md) resulting from the `billing_cycle_anchor` being `unchanged`. When the `billing_cycle_anchor` is set to `now` (default value), no prorations are generated. If no value is passed, the default is `create_prorations`.
Possible enum values:
  - `always_invoice`
    Always invoice immediately for prorations.

  - `create_prorations`
    Will cause proration invoice items to be created when applicable. These proration items will only be invoiced immediately under [certain conditions](https://docs.stripe.com/docs/subscriptions/upgrading-downgrading.md#immediate-payment).

  - `none`
    Disable creating prorations in this request.

- `proration_date` (timestamp, optional)
  If set, prorations will be calculated as though the subscription was resumed at the given time. This can be used to apply exactly the same prorations that were previewed with the [create preview](https://stripe.com/docs/api/invoices/create_preview) endpoint.
