Create Card Payment
Pays down the outstanding balance of a payment card. The repayment is settled synchronously against the card’s loan application and returns status: posted on success. Autopay must be disabled on the card unless your partner configuration settles from a partner FBO account. Omit account_id to debit the DDA account attached to the card.
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Path parameters
Request
Settlement rail. Defaults to book_transfer, the only rail currently implemented. ach and instant are reserved for future use — sending either records the repayment with status: error and returns a 400 payment_error.
Response
Always posted on a 201 response — the repayment is settled before the response is returned. Attempts that fail to settle return an error status code instead.
