OAuth based authentication validates the identity of the client that attempts to establish a trust on the system by using an authentication protocol.

OAuth 2.0 - Open Authorization is the industry-standard protocol for authorization that focuses on client developer simplicity while providing specific authorization flows for web applications, desktop applications, and mobile
devices.

## Inbound {#oauth-inbound-and-outbound__section_rjz_bgl_nwb}

Create an endpoint for external clients that access your instance. This creates an OAuth client application record and generates a client ID and client secret that the client requires access to the restricted resources on the
instance. For more information, see [OAuth inbound](https://www.servicenow.com/docs/pmiLPtw7E6o5Y8MdkgHGdQ "OAuth Inbound authentication allows trusted external applications to securely access ServiceNow APIs, helping to keep connections controlled and authorized.").
