# /oauth2/connect/checkSession

Endpoint to check session state as per [OpenID Connect Session Management 1.0 - draft 5](https://openid.net/specs/openid-connect-session-1_0-10.html).

The relying party client creates an invisible iframe that embeds the URL to the endpoint (by setting it as the `src` attribute of the `iframe` tag).

The endpoint accepts postMessage API requests from the iframe, and it postMessages back with the login status of the user in AM.

The endpoint is always accessed from the root realm. For example, `https://openam.example.com:8443/openam/oauth2/connect/checkSession`.
