=== Invalidate token API
++++
<titleabbrev>Invalidate token</titleabbrev>
++++

Invalidates one or more access tokens or refresh tokens.

[[security-api-invalidate-token-request]]
==== {api-request-title}

`DELETE /_security/oauth2/token`

[[security-api-invalidate-token-desc]]
==== {api-description-title}

The access tokens returned by the <<security-api-get-token,get token API>> have a
finite period of time for which they are valid and after that time period, they 
can no longer be used. That time period is defined by the 
`xpack.security.authc.token.timeout` setting. For more information, see 
<<token-service-settings>>.

The refresh tokens returned by the <<security-api-get-token,get token API>> are
only valid for 24 hours. They can also be used exactly once.

If you want to invalidate one or more access or refresh tokens immediately, use
this invalidate token API.

[[security-api-invalidate-token-request-body]]
==== {api-request-body-title}

The following parameters can be specified in the body of a DELETE request and
pertain to invalidating tokens:

`token`::
(Optional, string) An access token. This parameter cannot be used any of
`refresh_token`, `realm_name` or `username` are used.

`refresh_token`::
(Optional, string) A refresh token. This parameter cannot be used any of
`refresh_token`, `realm_name` or `username` are used.

`realm_name`::
(Optional, string) The name of an authentication realm. This parameter cannot be
used with either `refresh_token` or `token`.

`username`::
(Optional, string) The username of a user. This parameter cannot be used with
either `refresh_token` or `token`

NOTE: While all parameters are optional, at least one of them is required. More
specifically, either one of `token` or `refresh_token` parameters is required.
If none of these two are specified, then `realm_name` and/or `username` need to
be specified.


[[security-api-invalidate-token-response-body]]
==== {api-response-body-title}

A successful call returns a JSON structure that contains the number of tokens
that were invalidated, the number of tokens that had already been invalidated,
and potentially a list of errors encountered while invalidating specific tokens.

[[security-api-invalidate-token-example]]
==== {api-examples-title}

For example, if you create a token using the `client_credentials` grant type as
follows:

[source,js]
--------------------------------------------------
POST /_security/oauth2/token
{
  "grant_type" : "client_credentials"
}
--------------------------------------------------
// CONSOLE
// TEST

The get token API returns the following information about the access token:

[source,js]
--------------------------------------------------
{
  "access_token" : "dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ==",
  "type" : "Bearer",
  "expires_in" : 1200
}
--------------------------------------------------
// CONSOLE
// TESTRESPONSE[s/dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ==/$body.access_token/]

This access token can now be immediately invalidated, as shown in the following
example:

[source,js]
--------------------------------------------------
DELETE /_security/oauth2/token
{
  "token" : "dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ=="
}
--------------------------------------------------
// CONSOLE
// TEST[s/dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ==/$body.access_token/]
// TEST[continued]

If you used the `password` grant type to obtain a token for a user, the response
might also contain a refresh token. For example:

[source,js]
--------------------------------------------------
POST /_security/oauth2/token
{
  "grant_type" : "password",
  "username" : "test_admin",
  "password" : "x-pack-test-password"
}
--------------------------------------------------
// CONSOLE
// TEST

The get token API returns the following information:

[source,js]
--------------------------------------------------
{
  "access_token" : "dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ==",
  "type" : "Bearer",
  "expires_in" : 1200,
  "refresh_token": "vLBPvmAB6KvwvJZr27cS"
}
--------------------------------------------------
// CONSOLE
// TESTRESPONSE[s/dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ==/$body.access_token/]
// TESTRESPONSE[s/vLBPvmAB6KvwvJZr27cS/$body.refresh_token/]

The refresh token can now also be immediately invalidated as shown 
in the following example:

[source,js]
--------------------------------------------------
DELETE /_security/oauth2/token
{
  "refresh_token" : "vLBPvmAB6KvwvJZr27cS"
}
--------------------------------------------------
// CONSOLE
// TEST[s/vLBPvmAB6KvwvJZr27cS/$body.refresh_token/]
// TEST[continued]

The following example invalidates all access tokens and refresh tokens for the
`saml1` realm immediately:

[source,js]
--------------------------------------------------
DELETE /_security/oauth2/token
{
  "realm_name" : "saml1"
}
--------------------------------------------------
// CONSOLE
// TEST

The following example invalidates all access tokens and refresh tokens for the
user `myuser` in all realms immediately:

[source,js]
--------------------------------------------------
DELETE /_security/oauth2/token
{
  "username" : "myuser"
}
--------------------------------------------------
// CONSOLE
// TEST

Finally, the following example invalidates all access tokens and refresh tokens
for the user `myuser` in the `saml1` realm immediately:

[source,js]
--------------------------------------------------
DELETE /_security/oauth2/token
{
  "username" : "myuser",
  "realm_name" : "saml1"
}
--------------------------------------------------
// CONSOLE
// TEST

[source,js]
