SVB Authorization API is one of 10 APIs that [First Citizens BancShares](https://apis.io/providers/first-citizens-bancshares/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication, Security, Commercial Banking, and United States. The published artifact set on APIs.io includes API documentation and an API reference.

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.
