        Only applies to subscriptions with `collection_method=charge_automatically`.

        Use `allow_incomplete` to create Subscriptions with `status=incomplete` if the first invoice can't be paid. Creating Subscriptions with this status allows you to manage scenarios where additional customer actions are needed to pay a subscription's invoice. For example, SCA regulation may require 3DS authentication to complete payment. See the [SCA Migration Guide](https://stripe.com/docs/billing/migration/strong-customer-authentication) for Billing to learn more. This is the default behavior.

        Use `default_incomplete` to create Subscriptions with `status=incomplete` when the first invoice requires payment, otherwise start as active. Subscriptions transition to `status=active` when successfully confirming the PaymentIntent on the first invoice. This allows simpler management of scenarios where additional customer actions are needed to pay a subscription's invoice, such as failed payments, [SCA regulation](https://stripe.com/docs/billing/migration/strong-customer-authentication), or collecting a mandate for a bank debit payment method. If the PaymentIntent is not confirmed within 23 hours Subscriptions transition to `status=incomplete_expired`, which is a terminal state.

        Use `error_if_incomplete` if you want Stripe to return an HTTP 402 status code if a subscription's first invoice can't be paid. For example, if a payment method requires 3DS authentication due to SCA regulation and further customer action is needed, this parameter doesn't create a Subscription and returns an error instead. This was the default behavior for API versions prior to 2019-03-14. See the [changelog](https://stripe.com/docs/upgrades#2019-03-14) to learn more.

        `pending_if_incomplete` is only used with updates and cannot be passed when creating a Subscription.

        Subscriptions with `collection_method=send_invoice` are automatically activated regardless of the first Invoice status.

        Use `allow_incomplete` to transition the subscription to `status=past_due` if a payment is required but cannot be paid. This allows you to manage scenarios where additional user actions are needed to pay a subscription's invoice. For example, SCA regulation may require 3DS authentication to complete payment. See the [SCA Migration Guide](https://stripe.com/docs/billing/migration/strong-customer-authentication) for Billing to learn more. This is the default behavior.

        Use `default_incomplete` to transition the subscription to `status=past_due` when payment is required and await explicit confirmation of the invoice's payment intent. This allows simpler management of scenarios where additional user actions are needed to pay a subscription's invoice. Such as failed payments, [SCA regulation](https://stripe.com/docs/billing/migration/strong-customer-authentication), or collecting a mandate for a bank debit payment method.

        Use `pending_if_incomplete` to update the subscription using [pending updates](https://stripe.com/docs/billing/subscriptions/pending-updates). When you use `pending_if_incomplete` you can only pass the parameters [supported by pending updates](https://stripe.com/docs/billing/pending-updates-reference#supported-attributes).

        Use `error_if_incomplete` if you want Stripe to return an HTTP 402 status code if a subscription's invoice cannot be paid. For example, if a payment method requires 3DS authentication due to SCA regulation and further user action is needed, this parameter does not update the subscription and returns an error instead.

    Possible values are `incomplete`, `incomplete_expired`, `trialing`, `active`, `past_due`, `canceled`, `unpaid`, or `paused`.

    For `collection_method=charge_automatically` a subscription moves into `incomplete` if the initial payment attempt fails. A subscription in this status can only have metadata and default_source updated. Once the first invoice is paid, the subscription moves into an `active` status. If the first invoice is not paid within 23 hours, the subscription transitions to `incomplete_expired`. This is a terminal status, the open invoice will be voided and no further invoices will be generated.

    A subscription that is currently in a trial period is `trialing` and moves to `active` when the trial period is over.

    A subscription can only enter a `paused` status [when a trial ends without a payment method](https://stripe.com/docs/billing/subscriptions/trials#create-free-trials-without-payment). A `paused` subscription doesn't generate invoices and can be resumed after your customer adds their payment method. The `paused` status is different from [pausing collection](https://stripe.com/docs/billing/subscriptions/pause-payment), which still generates invoices and leaves the subscription's status unchanged.

    If subscription `collection_method=charge_automatically`, it becomes `past_due` when payment is required but cannot be paid (due to failed payment or awaiting additional user actions). Once Stripe has exhausted all payment retry attempts, the subscription will become `canceled` or `unpaid` (depending on your subscriptions settings).

    If subscription `collection_method=send_invoice` it becomes `past_due` when its invoice is not paid by the due date, and `canceled` or `unpaid` if it is still not paid by an additional deadline after that. Note that when a subscription has a status of `unpaid`, no subsequent invoices will be attempted (invoices will be created, but then immediately automatically closed). After receiving updated payment information from a customer, you may choose to reopen and pay their closed invoices.

        Updates an existing subscription to match the specified parameters.
        When changing prices or quantities, we optionally prorate the price we charge next month to make up for any price changes.
        To preview how the proration is calculated, use the [create preview](https://stripe.com/docs/api/invoices/create_preview) endpoint.

        By default, we prorate subscription changes. For example, if a customer signs up on May 1 for a 100 price, they'll be billed 100 immediately. If on May 15 they switch to a 200 price, then on June 1 they'll be billed 250 (200 for a renewal of her subscription, plus a 50 prorating adjustment for half of the previous month's 100 difference). Similarly, a downgrade generates a credit that is applied to the next invoice. We also prorate when you make quantity changes.

        Switching prices does not normally change the billing date or generate an immediate charge unless:


        The billing interval is changed (for example, from monthly to yearly).
        The subscription moves from free to paid.
        A trial starts or ends.


        In these cases, we apply a credit for the unused time on the previous price, immediately charge the customer using the new price, and reset the billing date. Learn about how [Stripe immediately attempts payment for subscription changes](https://stripe.com/docs/billing/subscriptions/upgrade-downgrade#immediate-payment).

        If you want to charge for an upgrade immediately, pass proration_behavior as always_invoice to create prorations, automatically invoice the customer for those proration adjustments, and attempt to collect payment. If you pass create_prorations, the prorations are created but not automatically invoiced. If you want to bill the customer for the prorations before the subscription's renewal date, you need to manually [invoice the customer](https://stripe.com/docs/api/invoices/create).

        If you don't want to prorate, set the proration_behavior option to none. With this option, the customer is billed 100 on May 1 and 200 on June 1. Similarly, if you set proration_behavior to none when switching between different billing intervals (for example, from monthly to yearly), we don't generate any credits for the old subscription's unused time. We still reset the billing date and bill immediately for the new subscription.

        Updating the quantity on a subscription many times in an hour may result in [rate limiting. If you need to bill for a frequently changing quantity, consider integrating <a href="/docs/billing/subscriptions/usage-based">usage-based billing](https://stripe.com/docs/rate-limits) instead.

        If you don't want to prorate, set the proration_behavior option to none. With this option, the customer is billed 100 on May 1 and 200 on June 1. Similarly, if you set proration_behavior to none when switching between different billing intervals (for example, from monthly to yearly), we don't generate any credits for the old subscription's unused time. We still reset the billing date and bill immediately for the new subscription.

        Updating the quantity on a subscription many times in an hour may result in [rate limiting. If you need to bill for a frequently changing quantity, consider integrating <a href="/docs/billing/subscriptions/usage-based">usage-based billing](https://stripe.com/docs/rate-limits) instead.
