Subscriptions

Update a subscription

Updates a subscription. Provide at least one of trial_end or payment_method.

Provide trial_end to set when the trial ends and the first paid billing period begins. trial_end must be at least one day in the future. Fintoc aligns the subscription’s billing_cycle_anchor to trial_end and sets its status to trialing until then.

Provide payment_method to swap the payment method the subscription charges against. The payment method must be active, belong to the subscription’s customer, and be a pac or card. After the swap, Fintoc charges every next payment against the new payment method, including any invoice that is already open. Swapping does not charge the subscription immediately.

Canceled subscriptions cannot be updated.
