Record an offline AP payment made to a vendor.

An offline payment is a payment made outside the BILL system. BILL simply applies the recorded payment amount to one or more bills for the vendor. BILL does not process the payment or transfer funds to the vendor when you record an AP payment with this endpoint.

Use POST /v3/payments to create a payment with the BILL system. When you pay with POST /v3/payments, BILL processes the payment and transfers funds from your BILL organization funding account to the vendor.
