TxB APIs allow you to originate payments and collections requests on-demand via US Fedwire, US ACH, CHAPS, and SWIFT payment methods. TxB APIs are payment rail and geography agnostic, so you don't need to learn a new API every time you add a new payment rail. Use these services to create customer facing payment applications (e.g., a checkout flow) or to power internal automated payment procedures (e.g., automatically paying a supplier once an invoice has been approved).
