Functions

Cancels a customer’s subscription immediately. The customer will not be charged again for the subscription.

Creates a new subscription on an existing customer. Each customer can have up to 500 active or scheduled subscriptions.

Removes the currently applied discount on a subscription.

By default, returns a list of subscriptions that have not been canceled. In order to list canceled subscriptions, specify status=canceled.

Initiates resumption of a paused subscription, optionally resetting the billing cycle anchor and creating prorations. If a resumption invoice is generated, it must be paid or marked uncollectible before the subscription will be unpaused. If payment succeeds the subscription will become active, and if payment fails the subscription will be past_due. The resumption invoice will void automatically if not paid by the expiration date.

Retrieves the subscription with the given ID.

Search for subscriptions you’ve previously created using Stripe’s Search Query Language.Don’t use search in read-after-write flows where strict consistency is necessary. Under normal operating conditions, data is searchable in less than a minute. Occasionally, propagation of new or updated data can be up to an hour behind during outages. Search functionality is not available to merchants in India.

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 upcoming invoice endpoint.

The subscription type.

  • application ID of the Connect Application that created the subscription.
  • application_fee_percent 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.
  • automatic_tax
  • billing_cycle_anchor 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.
  • billing_cycle_anchor_config The fixed values used to calculate the billing_cycle_anchor.
  • billing_thresholds Define thresholds at which an invoice will be sent, and the subscription advanced to a new billing period
  • cancel_at A date in the future at which the subscription will automatically get canceled
  • cancel_at_period_end If the subscription has been canceled with the at_period_end flag set to true, cancel_at_period_end on the subscription will be true. You can use this attribute to determine whether a subscription that has a status of active is scheduled to be canceled at the end of the current period.
  • canceled_at 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.
  • cancellation_details Details about why this subscription was cancelled
  • collection_method 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.
  • created Time at which the object was created. Measured in seconds since the Unix epoch.
  • currency Three-letter ISO currency code, in lowercase. Must be a supported currency.
  • current_period_end End of the current period that the subscription has been invoiced for. At the end of this period, a new invoice will be created.
  • current_period_start Start of the current period that the subscription has been invoiced for.
  • customer ID of the customer who owns the subscription.
  • days_until_due 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.
  • default_payment_method ID of the default payment method for the subscription. It must belong to the customer associated with the subscription. This takes precedence over default_source. If neither are set, invoices will use the customer's invoice_settings.default_payment_method or default_source.
  • default_source ID of the default payment source for the subscription. It must belong to the customer associated with the subscription and be in a chargeable state. If default_payment_method is also set, default_payment_method will take precedence. If neither are set, invoices will use the customer's invoice_settings.default_payment_method or default_source.
  • default_tax_rates The tax rates that will apply to any subscription item that does not have tax_rates set. Invoices created will have their default_tax_rates populated from the subscription.
  • description 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.
  • discount Describes the current discount applied to this subscription, if there is one. When billing, a discount applied to a subscription overrides a discount applied on a customer-wide basis.
  • ended_at If the subscription has ended, the date the subscription ended.
  • id Unique identifier for the object.
  • items List of subscription items, each with an attached price.
  • latest_invoice The most recent invoice this subscription has generated.
  • livemode Has the value true if the object exists in live mode or the value false if the object exists in test mode.
  • metadata 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_invoice Specifies the approximate timestamp on which any pending invoice items will be billed according to the schedule provided at pending_invoice_item_interval.
  • object String representing the object's type. Objects of the same type share the same value.
  • on_behalf_of The account (if any) the charge was made on behalf of for charges associated with this subscription. See the Connect documentation for details.
  • pause_collection If specified, payment collection for this subscription will be paused.
  • payment_settings Payment settings passed on to invoices created by the subscription.
  • pending_invoice_item_interval Specifies an interval for how often to bill for any pending invoice items. It is analogous to calling Create an invoice for the given subscription at the specified interval.
  • pending_setup_intent You can use this SetupIntent to collect user authentication when creating a subscription without immediate payment or updating a subscription's payment method, allowing you to optimize for off-session payments. Learn more in the SCA Migration Guide.
  • pending_update If specified, pending updates that will be applied to the subscription once the latest_invoice has been paid.
  • schedule The schedule attached to the subscription
  • start_date Date when the subscription was first created. The date might differ from the created date due to backdating.
  • status Possible values are incomplete, incomplete_expired, trialing, active, past_due, canceled, or unpaid.

For collection_method=charge_automatically a subscription moves into incomplete if the initial payment attempt fails. A subscription in this state can only have metadata and default_source updated. Once the first invoice is paid, the subscription moves into an active state. If the first invoice is not paid within 23 hours, the subscription transitions to incomplete_expired. This is a terminal state, 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.

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.

  • test_clock ID of the test clock this subscription belongs to.
  • transfer_data The account (if any) the subscription's payments will be attributed to for tax reporting, and where funds from each payment will be transferred to for each of the subscription's invoices.
  • trial_end If the subscription has a trial, the end of that trial.
  • trial_settings Settings related to subscription trials.
  • trial_start If the subscription has a trial, the beginning of that trial.
@type transfer_data() :: %{
  optional(:amount_percent) => number(),
  optional(:destination) => binary()
}

If specified, the funds from the subscription's invoices will be transferred to the destination and the ID of the resulting transfers will be found on the resulting charges.

  opts :: Keyword.t()
) :: {:ok, t()} | {:error, Stripe.ApiErrors.t()} | {:error, term()}

Cancels a customer’s subscription immediately. The customer will not be charged again for the subscription.

Note, however, that any pending invoice items that you’ve created will still be charged for at the end of the period, unless manually deleted. If you’ve set the subscription to cancel at the end of the period, any pending prorations will also be left in place and collected at the end of the period. But if the subscription is set to cancel immediately, pending prorations will be removed.

By default, upon subscription cancellation, Stripe will stop automatic collection of all finalized invoices for the customer. This is intended to prevent unexpected payment attempts after the customer has canceled a subscription. However, you can resume automatic collection of the invoices manually after subscription cancellation to have us proceed. Or, you could check for unpaid invoices before allowing the customer to cancel the subscription at all.

) :: {:ok, t()} | {:error, Stripe.ApiErrors.t()} | {:error, term()}

Creates a new subscription on an existing customer. Each customer can have up to 500 active or scheduled subscriptions.

When you create a subscription with collection_method=charge_automatically, the first invoice is finalized as part of the request.The payment_behavior parameter determines the exact behavior of the initial payment.

To start subscriptions where the first invoice always begins in a draft status, use subscription schedules instead.Schedules provide the flexibility to model more complex billing configurations that change over time.

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 upcoming invoice 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, or paid to free.
  • 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.

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.

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 usage-based billing instead.
