# Adds more flexibility for how you manage subscription end-of-period cancellations ## What’s new We introduced new [cancel_at](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview#create_subscription-cancel_at) enum values for subscriptions configured with [flexible behavior](https://docs.stripe.com/billing/subscriptions/billing-mode.md) (which have [billing_mode](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-04-30.preview#create_subscription-billing_mode) set to `flexible`). This change simplifies canceling a subscription at the end of a billing period with [mixed intervals](https://docs.stripe.com/billing/subscriptions/mixed-interval.md). The new [cancel_at](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview#create_subscription-cancel_at) enum values are: - `min_period_end` - `max_period_end` Use these values to cancel the earliest and latest [items.data.current_period_end](https://docs.stripe.com/api/subscriptions/object.md?api-version=2025-05-28.preview#subscription_object-items-data-current_period_end) amongst all subscription items. These new enum values set the cancelation date based on the current subscription’s `items.data.current_period_end`. Unlike [cancel_at_period_end](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview#create_subscription-cancel_at_period_end), these values are resolved to timestamps immediately and aren’t affected by further changes to `items.data.current_period_end`. The [cancel_at_period_end](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview#create_subscription-cancel_at_period_end) parameter is now deprecated. The behavior of this parameter is unchanged, but in the context of mixed interval subscriptions, it defaults to canceling at the earliest period end. ## Impact The following API endpoints support these new values: - [Create a subscription](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview) - [Update a subscription](https://docs.stripe.com/api/subscriptions/update.md?api-version=2025-05-28.preview) - [Create an invoice preview](https://docs.stripe.com/api/invoices/create_preview.md?api-version=2025-05-28.preview) If your integration currently uses the deprecated [cancel_at_period_end](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview#create_subscription-cancel_at_period_end) parameter to cancel subscriptions, use the new [cancel_at](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-05-28.preview#create_subscription-cancel_at) parameter with the `min_period_end` enum value instead. The `cancel_at_period_end` field on a Subscription isn’t compatible with the new `cancel_at` helpers. ## Changes #### REST API | Fields | Change | From → to | |
