## AI overview

This announcement presents a Hitachi Ltd. case study about using Keycloak as the authorization server for an API management cloud service for Japanese banks. The service enables banks to expose APIs securely to third-party fintech companies and provides FAPI-conformant API authorization.

## Source excerpt

Hitachi Ltd. uses Keycloak to make financial grade security easier. They are providing an API management cloud service for Japanese banks. Banks can open their APIs (like accessing bank accounts) to third-party fintech companies securely by using the service. One of the biggest challenges in the development phase was authorizing APIs for financial grade security. For API authorization in the financial sector, Financial-grade API (FAPI) is specified by the OpenID Foundation and widely adopted. By using Keycloak as an authorization server of the API management cloud service, they can provide a fully FAPI conformant API authorization for their customers.
