# API
The Security plugin REST API lets you programmatically create and manage users, roles, role mappings, action groups, and tenants.
---
#### Table of contents
1. TOC
{:toc}

## 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
plugins.security.restapi.roles_enabled: ["<role>", ...]
```
{% include copy.html %}
These roles can now access all APIs. To prevent access to certain APIs:
```yml
plugins.security.restapi.endpoints_disabled.<role>.<endpoint>: ["<method>", ...]
```
{% include copy.html %}
Roles also allow you to control access to specific REST APIs. You can add individual or multiple cluster permissions to a role and grant users access to associated APIs when they are mapped to the role. The following list of cluster permissions includes the endpoints that correspond to the Security REST APIs:
| **Permission** | **APIs granted** | **Description** |
|:-------------------------------|:-----------------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------------|
| restapi:admin/actiongroups | `/actiongroup` and `/actiongroups` | Permission to get, delete, create, and patch actions groups (including bulk updates). |
| restapi:admin/allowlist | `/allowlist` | Permission to add any endpoints and HTTP requests to a list of allowed endpoints and requests. |
| restapi:admin/internalusers | `/internaluser` and `/user` | Permission to add, retrieve, modify, and delete any user in the cluster. |
| restapi:admin/nodesdn | `/nodesdn` | Permission to add, retrieve, update, or delete any distinguished names from an allow list and enable communication between clusters and/or nodes. |
| restapi:admin/roles | `/roles` | Permission to add, retrieve, modify, and delete any roles in the cluster. |
| restapi:admin/rolesmapping | `/rolesmapping` | Permission to add, retrieve, modify, and delete any roles-mapping. |
| restapi:admin/ssl/certs/info | `/ssl/certs/info` | Permission to view current Transport and HTTP certificates. |
| restapi:admin/ssl/certs/reload | `/ssl/certs/reload` | Permission to view reload Transport and HTTP certificates. |
| restapi:admin/tenants | `/tenants` | Permission to get, delete, create, and patch tenants. |
Possible values for `endpoint` are:
- ACTIONGROUPS
- ROLES
- ROLESMAPPING
- INTERNALUSERS
- CONFIG
- CACHE
- SYSTEMINFO
- NODESDN
- SSL
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 `_plugins/_security/api/roles` or `_plugins/_security/api/internalusers`:
```yml
plugins.security.restapi.roles_enabled: ["all_access", "security_rest_api_access", "test-role"]
plugins.security.restapi.endpoints_disabled.test-role.ROLES: ["PUT", "POST", "DELETE", "PATCH"]
plugins.security.restapi.endpoints_disabled.test-role.INTERNALUSERS: ["PUT", "POST", "DELETE", "PATCH"]
```
{% include copy.html %}
To use the PUT and PATCH methods for the [configuration APIs](#configuration), add the following line to `opensearch.yml`:
```yml
plugins.security.unsupported.restapi.allow_securityconfig_modification: true
```
{% include copy.html %}
## 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
```
{% include copy.html %}
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
```
{% include copy.html %}
Hidden resources are automatically reserved.
To add or remove these flags, modify `config/opensearch-security/internal_users.yml` and run `plugins/opensearch-security/tools/securityadmin.sh`.

```
### Create user
Introduced 1.0
{: .label .label-purple }
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 `opendistro_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]({{site.url}}{{site.baseurl}}/security/access-control/users-roles#predefined-roles). For instructions on how to create a role, refer to [creating a role](#create-role).
#### Request

>Due to word boundaries associated with Unicode special characters, the Unicode standard analyzer cannot index a [text field type]({{site.url}}{{site.baseurl}}/opensearch/supported-field-types/text/) value as a whole value when it includes one of these special characters. As a result, a text field value that includes a special character is parsed by the standard analyzer as multiple values separated by the special character, effectively tokenizing the different elements on either side of it.
>
>For example, since the values in the fields ```"user.id": "User-1"``` and ```"user.id": "User-2"``` contain the hyphen/minus sign, this special character will prevent the analyzer from distinguishing between the two different users for `user.id` and interpret them as one and the same. This can lead to unintentional filtering of documents and potentially compromise control over their access.
>
>To avoid this circumstance, you can use a custom analyzer or map the field as `keyword`, which performs an exact-match search. See [Keyword field type]({{site.url}}{{site.baseurl}}/opensearch/supported-field-types/keyword/) for the latter option.
>
>For a list of characters that should be avoided when field type is `text`, see [Word Boundaries](https://unicode.org/reports/tr29/#Word_Boundaries).

## Distinguished names
These REST APIs let a super admin (or a user with sufficient permissions to access this API) add, retrieve, update, or delete any distinguished names from an allow list to enable communication between clusters and/or nodes.
Before you can use the REST API to configure the allow list, you must first add the following line to `opensearch.yml`:
```yml
plugins.security.nodes_dn_dynamic_config_enabled: true
```
{% include copy.html %}
### Get distinguished names

## Audit logs
The following API is available for audit logging in the Security plugin.
### Enable Audit Logs
This API allows you to enable or disable audit logging, define the configuration for audit logging and compliance, and make updates to settings.
For details on using audit logging to track access to OpenSearch clusters, as well as information on further configurations, see [Audit logs]({{site.url}}{{site.baseurl}}/security/audit-logs/index/).
You can do an initial configuration of audit logging in the `audit.yml` file, found in the `opensearch-project/security/config` directory. Thereafter, you can use the REST API or Dashboards for further changes to the configuration.

```json
GET /_opendistro/_security/api/audit
```
{% include copy-curl.html %}
**PUT**
A PUT call updates the audit configuration.
```json
PUT /_opendistro/_security/api/audit/config
{
"enabled": true,
"audit": {
"ignore_users": [],
"ignore_requests": [],
"disabled_rest_categories": [
"AUTHENTICATED",

```
{% include copy-curl.html %}
**PATCH**
A PATCH call is used to update specified fields in the audit configuration. The PATCH method requires an operation, a path, and a value to complete a valid request. For details on using the PATCH method, see the following [Patching resources](https://en.wikipedia.org/wiki/PATCH_%28HTTP%29#Patching_resources) description at Wikipedia.
Using the PATCH method also requires a user to have a security configuration that includes admin certificates for encryption. To find out more about these certificates, see [Configuring admin certificates]({{site.url}}{{site.baseurl}}/security/configuration/tls/#configuring-admin-certificates).
```bash
curl -X PATCH -k -i --cert <admin_cert file name> --key <admin_cert_key file name> <domain>/_opendistro/_security/api/audit -H 'Content-Type: application/json' -d'[{"op":"add","path":"/config/enabled","value":"true"}]'
```
{% include copy.html %}
OpenSearch Dashboards Dev Tools do not currently support the PATCH method. You can use [curl](https://curl.se/), [Postman](https://www.postman.com/), or another alternative process to update the configuration using this method. To follow the GitHub issue for support of the PATCH method in Dashboards, see [issue #2343](https://github.com/opensearch-project/OpenSearch-Dashboards/issues/2343).
