The Clearing House (RTP)

RTP Network (ISO 20022 Messaging)

The RTP network is The Clearing House's real-time payments scheme for the United States, moving credit-push payments instantly, 24/7/365, with final settlement up to $10 million per transaction. It is defined by published ISO 20022 message specifications rather than an open self-serve REST API: Credit Transfer (pacs.008), Message Status Report (pacs.002), Request for Payment (pain.013/pain.014), Request for Information (camt.026/camt.028), Request for Return of Funds (camt.056/camt.029), Payment Acknowledgement (camt.035), Stand-Alone Remittance Advice (remt.001), and the Business Application Header (BAH). Access is via participating financial institutions and registered technology providers; no downloadable OpenAPI is published by TCH.
