The Wire Transfer API, delivered through KeyBank's combined RTP and Wire Payments service, facilitates high-value domestic wire payments from commercial accounts. It provides operations to initiate a payment, validate payment details before submission, and look up RTP/wire network participants by routing number. Requests are authenticated with OAuth2 bearer tokens and mutual TLS client certificates and carry an x-fapi-interaction-id header; production runs on https://partner-api.key.com with a QV sandbox.
