Certificate-based authentication lets you mutually authenticate inbound API requests using certificates from a trusted certificate authority (CA).

Certificate-based authentication for inbound web services

:   Authenticate inbound requests to ServiceNow SOAP and REST APIs. To set up mutual authentication for inbound web services, see [Set up certificate-based authentication](https://www.servicenow.com/docs/wcDYuVgSjDWkfiSWlnnhPA "Set up mutual authentication for either user interface-based logins or inbound web services.").

Note:  
* Certificate Based Authentication is not supported on the On-Prem and edge encryption enabled instance.
