Subscriptions

Create a subscription

Creates a subscription that bills a customer on a recurring cadence, in the live or test mode of the API key used. Each item defines its price through price_data, referencing an existing product (product) or defining one inline (product_data). All items must share a compatible currency (CLF items bill alongside CLP) and the same recurring interval and interval_count. A subscription can have up to 10 items. The collection_method decides how Fintoc collects every invoice the subscription generates. With charge_automatically, the default, Fintoc charges payment_method on every billing cycle, so the payment method is required. With send_invoice, Fintoc leaves each invoice open for you to collect, and payment_method is optional. A payment_method must be active and have a type of pac or card; subscriptions do not support bank_transfer. Without trial_end, Fintoc sets the billing_cycle_anchor to the creation time and finalizes an initial invoice immediately. With charge_automatically, the subscription starts incomplete and becomes active once that first payment succeeds. With send_invoice, the subscription starts active and the initial invoice stays open. For a zero-amount subscription, Fintoc marks the initial invoice paid and the subscription starts active. With trial_end, the subscription’s status is trialing. Fintoc sets the billing_cycle_anchor to the trial end and generates the first invoice when the trial ends.
