The Subscription object

A subscription bills your customer on a recurring schedule. The subscription groups billable items, tracks the billing cycle, and generates an invoice for each period. The subscription reflects whether billing is active, in a trial, or canceled.

Attribute	Type	Description
`id`	`string`	Unique identifier for the subscription.
`object`	`string`	Type of the object. Always `subscription`.
`billing_cycle_anchor`	`string`	Reference point used to align future invoices. ISO 8601 datetime in UTC.
`collection_method`	`string`	One of `charge_automatically` or `send_invoice`. With `charge_automatically`, Fintoc collects each invoice using the attached payment method. With `send_invoice`, Fintoc leaves each invoice open for you to collect.
`created_at`	`string`	ISO 8601 datetime in UTC when the subscription was created.
`customer`	`string`	ID of the customer this subscription bills.
`items`	`array`	List of subscription item objects. See the Subscription Item attributes below.
`metadata`	`object`	Set of key-value pairs you can attach to the subscription, useful for storing additional structured information.
`mode`	`string`	One of `live` or `test`.
`payment_method`	`string` or `null`	ID of the payment method used to charge this subscription automatically. `null` if no payment method is attached.
`status`	`string`	One of `active`, `incomplete` (the first invoice payment has not yet succeeded), `trialing` (the trial period has not ended), or `canceled` (the subscription stopped generating invoices). With `send_invoice`, the subscription starts `active` because Fintoc does not start an automatic charge. With `charge_automatically`, the subscription starts `incomplete` and turns `active` once the first payment succeeds.
`trial_end`	`string` or `null`	ISO 8601 datetime in UTC marking the end of the trial period. `null` if the subscription has no trial.

With send_invoice, Fintoc never contacts your customer. Collecting each invoice is your responsibility, whether you send its payment link, charge it on demand, or take the money outside Fintoc. An active subscription means Fintoc keeps generating invoices, not that your customer keeps paying those invoices.

Attaching a payment method to a subscription does not change how Fintoc collects its invoices. The collection method changes only through Update a subscription.
