Creates a payment intent that charges a previously saved payment method, in the live or test mode of the API key used. Unlike POST /v1/payment_intents, which starts a customer-present flow completed through the Fintoc widget, this endpoint charges the payment_method directly, with no customer interaction and no widget token. This endpoint does not accept v1-only parameters such as recipient_account, customer_email, payment_type, or expires_at. The charge starts in the created status; Fintoc processes the charge asynchronously, so subscribe to webhooks to track the charge's progress. Available for organizations on API version 2026-02-01 or later.
