# API

The security plugin REST API lets you programmatically create and manage users, roles, role mappings, action groups, and tenants.

## Access control for the API

Just like OpenSearch permissions, you control access to the security plugin REST API using roles. Specify roles in `opensearch.yml`:

```yml
opensearch_security.restapi.roles_enabled: ["<role>", ...]
```

These roles can now access all APIs. To prevent access to certain APIs:

```yml
opensearch_security.restapi.endpoints_disabled.<role>.<endpoint>: ["<method>", ...]
```

Possible values for `endpoint` are:

- ACTIONGROUPS
- ROLES
- ROLESMAPPING
- INTERNALUSERS
- CONFIG
- CACHE
- LICENSE
- SYSTEMINFO

Possible values for `method` are:

- GET
- PUT
- POST
- DELETE
- PATCH

For example, the following configuration grants three roles access to the REST API, but then prevents `test-role` from making PUT, POST, DELETE, or PATCH requests to `_opensearch/_security/api/roles` or `_opensearch/_security/api/internalusers`:

```yml
opensearch_security.restapi.roles_enabled: ["all_access", "security_rest_api_access", "test-role"]
opensearch_security.restapi.endpoints_disabled.test-role.ROLES: ["PUT", "POST", "DELETE", "PATCH"]
opensearch_security.restapi.endpoints_disabled.test-role.INTERNALUSERS: ["PUT", "POST", "DELETE", "PATCH"]
```

To use the PUT and PATCH methods for the [configuration APIs](#configuration), add the following line to `opensearch.yml`:

```yml
opensearch_security.unsupported.restapi.allow_securityconfig_modification: true
```


## Reserved and hidden resources

You can mark users, role, role mappings, and action groups as reserved. Resources that have this flag set to true can't be changed using the REST API or OpenSearch Dashboards.

To mark a resource as reserved, add the following flag:

```yml
kibana_user:
  reserved: true
```

Likewise, you can mark users, role, role mappings, and action groups as hidden. Resources that have this flag set to true are not returned by the REST API and not visible in OpenSearch Dashboards:

```yml
kibana_user:
  hidden: true
```

Hidden resources are automatically reserved.

To add or remove these flags, you need to modify `plugins/opensearch-security/securityconfig/internal_users.yml` and run `plugins/opensearch-security/tools/securityadmin.sh`.

## Account

### Get account details

Returns account details for the current user. For example, if you sign the request as the `admin` user, the response includes details for that user.

## Users

These calls let you create, update, and delete internal users. If you use an external authentication backend, you probably don't need to worry about internal users.


### Get user

#### Request

```
GET _opensearch/_security/api/internalusers/<username>
```


#### Sample response

```json
{
  "kirk": {
    "hash": "",
    "roles": [ "captains", "starfleet" ],
    "attributes": {
       "attribute1": "value1",
       "attribute2": "value2",
    }
  }
}
```


### Get users

#### Request

```
GET _opensearch/_security/api/internalusers/
```

#### Sample response

```json
{
  "kirk": {
    "hash": "",
    "roles": [ "captains", "starfleet" ],
    "attributes": {
       "attribute1": "value1",
       "attribute2": "value2",
    }
  }
}
```


### Delete user

#### Request

```
DELETE _opensearch/_security/api/internalusers/<username>
```

#### Sample response

```json
{
  "status":"OK",
  "message":"user kirk deleted."
}
```


### Create user

Creates or replaces the specified user. You must specify either `password` (plain text) or `hash` (the hashed user password). If you specify `password`, the security plugin automatically hashes the password before storing it.

Note that any role you supply in the `opensearch_security_roles` array must already exist for the security plugin to map the user to that role. To see predefined roles, refer to [the list of predefined roles](../users-roles/#predefined-roles). For instructions on how to create a role, refer to [creating a role](./#create-role).

#### Request

```json
PUT _opensearch/_security/api/internalusers/<username>
{
  "password": "kirkpass",
  "opensearch_security_roles": ["maintenance_staff", "weapons"],
  "backend_roles": ["captains", "starfleet"],
  "attributes": {
    "attribute1": "value1",
    "attribute2": "value2"
  }
}
```

#### Sample response

```json
{
  "status":"CREATED",
  "message":"User kirk created"
}
```


### Patch user

#### Request

```json
