You can’t look up the bank name directly through CyberSource, but you can resolve it yourself by referencing the official ACH Directory published by Nacha (the organization that maintains routing numbers). You can download their ACH Directory in CSV format and import it into your system, then query the routing number to return the bank’s name. Alternatively, there are several public APIs and data services (such as the Federal Reserve’s RDFI directory or third-party services) that let you submit a routing number and retrieve the corresponding bank information in real time. Just be sure to cache responses or maintain a local copy of the directory to avoid hitting rate limits or incurring excessive API costs. See details
