East West Bank Bridge Open Banking API
East West Bank's first-party commercial banking API program, delivered through the "Bridge Open Banking" developer portal for Global Transaction Services (GTS) clients. Documented capabilities let applications manage sub-accounts, retrieve account balances, transfer funds, and securely obtain information on commercial accounts. Developers create an application to obtain a single authentication credential and test against a sandbox of live test accounts and test payments. The program is early-stage and access is gated behind sales onboarding, so specifications are not publicly downloadable.
