SVB Authorization API
The Authorization API issues OAuth2 access tokens for the SVB commercial banking platform (now part of First Citizens). Partners exchange client credentials at /v1/security/oauth/token for a bearer token, then sign request payloads with a JSON Web Signature (JWS) using their registered keys. This API is the entry point for every other commercial banking product on the portal and defines the OAuth2 client-credentials plus request-signing security model used across the platform.
