Subscriptions

A Subscription resource represents a recurring charge to a Payment Instrument at regular intervals. Subscribers can be buyers, customers, or merchants.

When creating a Subscription, you have the option to use a Subscription Plan.

Limitations

  • Supported countries: At this time, subscriptions are available in the United States.
  • Supported payment methods: Subscriptions currently support recurring card payments and recurring bank account payments (ACH in USA).
  • Approved merchants: At this time, only approved merchants with one of the following processors can create subscriptions: DUMMY_V1 and FINIX_V1.

Create a Subscription

Create a Subscription resource to charge a Payment Instrument regularly.

If there is no trial period, the subscription will create a Transfer shortly after creation (within 60 minutes).

The following options are available when creating a subscription.

Adding a trial period

You can create a subscription with a trial period by providing trial_details in the request body. After creating a subscription, a Transfer will occur after the trial period has elapsed. The first_charge_at property in the response determines when the transfer will take place.

Using a Subscription Plan

Think of a Subscription Plan as a template for the Subscription resource. When creating a subscription, you can use a Subscription Plan by providing a subscription_plan_id. Doing so lets you base a subscription on existing values for amount, billing_interval, and more.

Update a Subscription
Update an existing Subscription resource, typically used for subscriptions created without a Subscription Plan. Note that you can only update specific resource fields.


Two common use cases for updating a Subscription are:


Updating the payment amount


This operation allows for adjusting the payment amount, such as when a subscriber decides to donate more or less money to a charity or upgrade/downgrade a product or service.


Updating billing details


If the subscriber wishes to change their payment details, you can update the [buyer_details.instrument_id] property with a new Payment Instrument.
