Goldman Sachs

Goldman Sachs Transaction Banking (TxB) API

Goldman Sachs Transaction Banking (TxB) provides programmatic access for eligible partners and clients to embed treasury and banking capabilities into their own ecosystem, organized around three functional domains: creating virtual accounts, originating payments and collections, and tracking balances and transaction activity. TxB APIs are payment-rail agnostic, executing domestic and cross-border payments across US Fedwire, US ACH and SWIFT. They are secured with mutual TLS and IP allowlisting, with per-call JWT step-up authentication; the documented test base is api.test.txb.gs.com. HTML-only docs, no public OpenAPI download.
