==== Examples

The following example invalidates the API key identified by specified `id` immediately:

[source,js]
--------------------------------------------------
DELETE /_security/api_key
{
  "id" : "dGhpcyBpcyBub3QgYSByZWFsIHRva2VuIGJ1dCBpdCBpcyBvbmx5IHRlc3QgZGF0YS4gZG8gbm90IHRyeSB0byByZWFkIHRva2VuIQ=="
}
--------------------------------------------------
// NOTCONSOLE

whereas the following example invalidates the API key identified by specified `name` immediately:

[source,js]
--------------------------------------------------
DELETE /_security/api_key
{
  "name" : "hadoop_myuser_key"
}
--------------------------------------------------
// NOTCONSOLE

The following example invalidates all API keys for the `native1` realm immediately:

[source,js]
--------------------------------------------------
DELETE /_security/api_key
{
  "realm_name" : "native1"
}
--------------------------------------------------
// NOTCONSOLE

The following example invalidates all API keys for the user `myuser` in all realms immediately:

[source,js]
--------------------------------------------------
DELETE /_security/api_key
{
  "username" : "myuser"
}
--------------------------------------------------
// NOTCONSOLE

Finally, the following example invalidates all API keys for the user `myuser` in
 the `native1` realm immediately:

[source,js]
--------------------------------------------------
DELETE /_security/api_key
{
  "username" : "myuser",
  "realm_name" : "native1"
}
--------------------------------------------------
// NOTCONSOLE

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