[Back](./) # How do I change a subscription that never expires to expire after a specific number of billing cycles? The **Expires After** field is only available when creating a new subscription. For an existing subscription, you can set this using Zoho Billing’s [Update a Subscription](/billing/api/v1/#Subscriptions_Update_a_subscription) API. Pass the number of billing cycles as the value for the `billing_cycles` parameter. The subscription will automatically expire after the specified number of cycles. * * *
