# Native SSO Logout Processing

`POST /api/{serviceId}/nativesso/logout`

The `/nativesso/logout` API is supposed to be used to support the concept of "logout from all applications"
in the context of [OpenID Connect Native SSO for Mobile Apps 1.0](https://openid.net/specs/openid-connect-native-sso-1_0.html)
(Native SSO). This is accomplished by deleting access/refresh token records associated with the
specified session ID. In Authlete's implementation, access/refresh token records can be associated
with a session ID only through the mechanism introduced by Native SSO.
