SVB Wires API
The Wires API (v2.1) initiates and manages domestic and international wire transfers. Partners create wires at /v2/payment/wires, retrieve wire status by id, and cancel pending wires, supporting high-value, time-critical treasury payment flows. It is part of the SVB commercial banking API family under First Citizens BancShares, secured with OAuth2 and JWS, and ships a wire-specific error catalog.
