=== SAML logout API
Submits a request to invalidate an access token and refresh token.
NOTE: This API is intended for use by custom web applications other than {kib}.
If you are using {kib}, see the <<saml-guide>>.
[[security-api-saml-logout-request]]
==== {api-request-title}
`POST /_security/saml/logout`
[[security-api-saml-logout-desc]]
==== {api-description-title}
This API invalidates the tokens that were generated for a user by the
<<security-api-saml-authenticate,SAML authenticate API>>.
If the SAML realm in {es} is configured accordingly and the SAML IdP supports
this, the {es} response contains a URL to redirect the user to the IdP
that contains a SAML logout request (starting an SP-initiated SAML Single Logout).
{es} exposes all the necessary SAML related functionality via the SAML APIs.
These APIs are used internally by {kib} in order to provide SAML based
authentication, but can also be used by other custom web applications or other
clients. See also <<security-api-saml-authenticate,SAML authenticate API>>,
<<security-api-saml-prepare-authentication,SAML prepare authentication API>>,
and <<security-api-saml-invalidate,SAML invalidate API>>.
[[security-api-saml-logout-request-body]]
==== {api-request-body-title}
`token`::
(Required, string) The access token that was returned as a response to calling the
<<security-api-saml-authenticate,SAML authenticate API>>. Alternatively, the most
recent token that was received after refreshing the original one by using a
`refresh_token`.
`refresh_token`::
(Optional, string) The refresh token that was returned as a response to calling the
<<security-api-saml-authenticate,SAML authenticate API>>. Alternatively, the
most recent refresh token that was received after refreshing the original access token.
[[security-api-saml-logout-response-body]]
==== {api-response-body-title}
`redirect`::
(string) A URL that contains a SAML logout request as a parameter. The user
can use this URL to be redirected back to the SAML IdP and to initiate Single
Logout.
[[security-api-saml-logout-example]]
==== {api-examples-title}
The following example invalidates the pair of tokens that were generated by
calling the <<security-api-saml-authenticate,SAML authenticate API>>
with a successful SAML response:
[source,console]
--------------------------------------------------
POST /_security/saml/logout
{
"token" : "46ToAxZVaXVVZTVKOVF5YU04ZFJVUDVSZlV3",
"refresh_token" : "mJdXLtmvTUSpoLwMvdBt_w"
}
--------------------------------------------------
// TEST[skip:can't test this without a valid SAML Response]
The API returns the following response:
[source,js]
--------------------------------------------------
{
"redirect" : "https://my-idp.org/logout/SAMLRequest=...."
}
