Adds or updates 
{stack-ov}/security-privileges.html#application-privileges[application privileges].

==== Request

`POST /_xpack/security/privilege` +

`PUT /_xpack/security/privilege`


==== Description

This API creates or updates privileges. To remove privileges, use the 
<<security-api-delete-privilege,delete application privilege API>>. 

For more information, see 
{stack-ov}/defining-roles.html#roles-application-priv[Application privileges].

To check a user's application privileges, use the
<<security-api-has-privileges,has privileges API>>.

==== Request Body

The body is a JSON object where the names of the fields are the application
names and the value of each field is an object. The fields in this inner
object are the names of the privileges and each value is a JSON object that 
includes the following fields:

`actions`:: (array-of-string) A list of action names that are granted by this
privilege. This field must exist and cannot be an empty array.

`metadata`:: (object) Optional meta-data. Within the `metadata` object, keys
that begin with `_` are reserved for system usage.


[[security-api-app-privileges-validation]]
==== Validation

Application Names::
    Application names are formed from a _prefix_, with an optional _suffix_ that
    conform to the following rules:
    * The prefix must begin with a lowercase ASCII letter
    * The prefix must contain only ASCII letters or digits
    * The prefix must be at least 3 characters long
    * If the suffix exists, it must begin with either `-` or `_`
    * The suffix cannot contain any of the following characters:
      `\\`, `/`, `*`, `?`, `"`, `<`, `>`, `|`, `,`, `*`
    * No part of the name can contain whitespace.

Privilege Names::
    Privilege names must begin with a lowercase ASCII letter and must contain
    only ASCII letters and digits along with the characters `_`, `-` and `.`

Action Names::
    Action names can contain any number of printable ASCII characters and must 
    contain at least one of the following characters: `/` `*`, `:`

==== Authorization

To use this API, you must have either:

- the `manage_security` cluster privilege (or a greater privilege such as `all`); _or_
- the _"Manage Application Privileges"_ global privilege for the application being referenced
  in the request

==== Examples

To add a single privilege, submit a PUT or POST request to the
`/_xpack/security/privilege/<application>/<privilege>` endpoint. For example:

[source,js]
--------------------------------------------------
PUT /_xpack/security/privilege
{
  "myapp": {
    "read": {
      "actions": [ <1>
        "data:read/*" , <2> 
        "action:login" ], 
        "metadata": { <3>
          "description": "Read access to myapp"
        }
      }
    }
}
--------------------------------------------------
// CONSOLE
<1> These strings have significance within the "myapp" application. {es} does not 
    assign any meaning to them.
<2> The use of a wildcard here (`*`) means that this privilege grants access to 
    all actions that start with `data:read/`. {es} does not assign any meaning 
    to these actions. However, if the request includes an application privilege 
    such as `data:read/users` or `data:read/settings`, the 
    <<security-api-has-privileges,has privileges API>> respects the use of a 
    wildcard and returns `true`.
<3> The metadata object is optional.

A successful call returns a JSON structure that shows whether the privilege has
been created or updated.

[source,js]
--------------------------------------------------
{
  "myapp": {
    "read": {
      "created": true <1>
    }
  }
}
--------------------------------------------------
// TESTRESPONSE
<1> When an existing privilege is updated, `created` is set to false.

To add multiple privileges, submit a POST request to the 
`/_xpack/security/privilege/` endpoint. For example:

[source,js]
--------------------------------------------------
PUT /_xpack/security/privilege
{
  "app01": {
    "read": {
      "actions": [ "action:login", "data:read/*" ]
    },
    "write": {
      "actions": [ "action:login", "data:write/*" ]
    }
  },
  "app02": {
    "all": {
      "actions": [ "*" ]
    }
  }
}
--------------------------------------------------
// CONSOLE

A successful call returns a JSON structure that shows whether the privileges 
have been created or updated.

[source,js]
--------------------------------------------------
{
  "app02": {
    "all": {
      "created": true
    }
  },
  "app01": {
    "read": {
      "created": true
    },
    "write": {
      "created": true
    }
  }
}
