Update a subscription on a customer

Changed on Sep 29, 2026

Updates an existing subscription on a customer to match the specified parameters. When changing plans or quantities, we will optionally prorate the price we charge next month to make up for any price changes. To preview how the proration will be calculated, use the upcoming invoice endpoint.

Request

Base URL: https://api.stripe.com
URL: https://api.stripe.com/v1/customers/{customer}/subscriptions/{subscription_exposed_id}
Auth: one of:
- HTTP basic
- HTTP bearer

Path parameters

customerstring required

subscription_exposed_idstring required

Response

Successful response.

application_fee_percentnumber nullable

A non-negative decimal between 0 and 100, with at most two decimal places. This represents the percentage of the subscription invoice total that will be transferred to the application owner's Stripe account.

billing_cycle_anchorinteger required

The reference point that aligns future billing cycle dates. It sets the day of week for week intervals, the day of month for month and year intervals, and the month of year for year intervals. The timestamp is in UTC format.

cancel_atinteger nullable

A date in the future at which the subscription will automatically get canceled

cancel_at_period_endboolean required

Whether this subscription will (if status=active) or did (if status=canceled) cancel at the end of the current billing period.

canceled_atinteger nullable

If the subscription has been canceled, the date of that cancellation. If the subscription was canceled with cancel_at_period_end, canceled_at will reflect the time of the most recent update request, not the end of the subscription period when the subscription is automatically moved to a canceled state.

collection_method'charge_automatically' | 'send_invoice' required

Either charge_automatically, or send_invoice. When charging automatically, Stripe will attempt to pay this subscription at the end of the cycle using the default source attached to the customer. When sending an invoice, Stripe will email your customer an invoice with payment instructions and mark the subscription as active.

createdinteger required

Time at which the object was created. Measured in seconds since the Unix epoch.

currencystring currency required

Three-letter ISO currency code, in lowercase. Must be a supported currency.

customer_accountstring nullable

ID of the account representing the customer who owns the subscription.

days_until_dueinteger nullable

Number of days a customer has to pay invoices generated by this subscription. This value will be null for subscriptions where collection_method=charge_automatically.

descriptionstring nullable

The subscription's description, meant to be displayable to the customer. Use this field to optionally store an explanation of the subscription for rendering in Stripe surfaces and certain local payment methods UIs.

ended_atinteger nullable

If the subscription has ended, the date the subscription ended.

idstring required

Unique identifier for the object.

livemodeboolean required

If the object exists in live mode, the value is true. If the object exists in test mode, the value is false.

metadataobject required

Set of key-value pairs that you can attach to an object. This can be useful for storing additional information about the object in a structured format.

next_pending_invoice_item_invoiceinteger nullable

Specifies the approximate timestamp on which any pending invoice items will be billed according to the schedule provided at pending_invoice_item_interval.

object'subscription' required

String representing the object's type. Objects of the same type share the same value.

start_dateinteger required

Date when the subscription was first created. The date might differ from the created date due to backdating.

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. 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, 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.

trial_endinteger nullable

If the subscription has a trial, the end of that trial.

trial_startinteger nullable

If the subscription has a trial, the beginning of that trial.
