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.
