  title: Availability of Funds
  x-ibm-name: sibs-psd2-funds-confirmation-api
  description: |
    Confirmation on the availability of funds API enables to check in real time if your clients have enough available funds to honor a purchase they are doing with the card you issued to them.

    With this API you may reduce the risk of being unable to recover the funds from your clients, after having guaranteed a payment to an acquirer or merchant.


    This API intends to provide an interface to access PSD2 Availability of Funds service.

    The API is designed on a REST model using JSON structures.
