What is the function of directory APIs in Faster Payments?

• A. To manage currency exchange rates
• B. To grant access to information related to customers or entities
• C. To establish transaction limits
• D. To verify user identity during transactions

Answer: (B)

The function of directory APIs in the context of Faster Payments primarily focuses on granting access to information related to customers or entities. These APIs play a crucial role in facilitating real-time payments by providing essential data about payees, such as their payment details and relevant identifiers. This access enables financial institutions to ensure that the correct recipient receives the payment, enhancing the overall speed and accuracy of transactions.

While other aspects of payment processing, such as transaction limits or customer verification, are essential for the secure and efficient completion of transactions, they are not the primary function of directory APIs. Instead, these APIs serve as a bridge of communication, allowing institutions to retrieve needed information to process payments accurately and efficiently. This integration of data supports a smooth and seamless experience for users participating in Faster Payments.
