Introduction

Open-AudIT has a JSON Restful API to be used both in the web interface and via JSON requests.

Open-AudIT's API

Open-AudIT is basing its API on http://jsonapi.org with the intention of providing simple and intuitive access in a manner familiar to developers.

In addition to this API, the web interface will use the same request format and supply some additional actions.

Access Model

The API is using our new model of access. Instead of a user <-> group model, we're using user <-> organisation. If you're having trouble at this early stage, just use the 'administrator' or 'open-audit_enterprise' account(s). We have not created the GUI screens to associate a user to an organisation as yet. If you wish to use another account you could run the below SQL directly to create the association:

INSERT INTO oa_user_org VALUES (NULL, $user_id, $org_id, 10, '');

Where your new $user_id and $org_id can be found in the Open-AudIT web interface.

The API uses a cookie. You can request a cookie by sending a POST to the URL below, containing the username and password attributes and values:

http://{server}/omk/open-audit/login

POSTing data

To create a resource, you should POST the required data. The format of your data shoudl be in the form:

data[attributes][ATTRIBUTE_NAME]

You should substitute the required column (eg, org_id) for ATTRIBUTE_NAME.

In the case where we store several fields (usually in JSON format) inside a BIGTEXT MySQL field (eg: credentials.credentials - the credentials column in the credentials table), you should use the format:

data[attributes][credentials][credentials][username]

Examples at the bottom of this page.

All endpoints also have a minimum list of required fields. These are:

applications -  'name', 'org_id'
attributes -    'name', 'org_id', 'type', 'resource', 'value'
collectors -    'name', 'org_id', 'status'
configuration - 'value'
connections -   'name', 'org_id'
credentials -   'name', 'org_id', 'type', 'credentials'
dashboards -    'name', 'options'
discoveries -   'name', 'org_id', 'type', 'network_address', 'other'
fields -        'name', 'org_id', 'type', 'placement', 'group_id'
files -         'name', 'org_id', 'path'
groups -        'name', 'org_id', 'sql'
ldap_servers -  'name', 'org_id', 'lang', 'host', 'port', 'secure', 'domain', 'type', 'version', 'use_roles', 'refresh'
licenses -      'name', 'org_id', 'org_descendants', 'purchase_count', 'match_string'
locations -     'name', 'org_id'
networks -      'name', 'org_id', 'network'
orgs -          'name', 'parent_id'
queries -       'name', 'org_id', 'sql', 'menu_category', 'menu_display'
roles -         'name', 'permissions'
scripts -       'name', 'org_id', 'options', 'based_on'
summaries -     'name', 'org_id', 'table', 'column', 'menu_category'
tasks -         'name', 'org_id', 'type', 'sub_resource_id', 'uuid', 'enabled', 'minute', 'hour', 'day_of_month', 'month', 'day_of_week'
users -         'name', 'org_id', 'lang', 'active', 'roles', 'orgs'
widgets -       'name', 'org_id', 'type'

The Endpoints

At present we have endpoints for nearly every collection. They are listed here - Collections.

Options

Format

Using the format option is useful when using a web browser but you wish to see the result in JSON format. Adding format=json achieves this. Normally a web browser will set its accept header to HTML, so in that case, we return the rendered page. Using an API to retrieve JSON you should set the accept header to "json/application". You can override this by providing the format option in the URL.

We tend to use the Google Chrome extension called Postman for testing actual restful queries. You might like to install and test with that. http://www.getpostman.com.

Action

When using the API the default action is determined according to the format and URL. You can override this by providing the 'action' option in the URL. An example of this is when creating a new item. You would normally use POST to /item but in the case of a web user, you need a web form to be able to fill out the item details. In that case, there is no facility for this in a typical JSON Restful API. We work around this by providing action=create in a GET request for the URL. IE - http://{server}/omk/open-audit/networks?action=create. The default action if nothing matches below is to return a collection of items.

API Routes

Request Method	ID	Resulting Function	Permission Required	URL Example	Notes
POST	n	create	{collection}::create	/{collection}	Insert a new {collection} entry.
GET	y	read	{collection}::read	/{collection}/{id}	Returns a {collection} details.
PATCH	y	update	{collection}::update	/{collection}/{id}	Update an attribute of a {collection} entry.
DELETE	y	delete	{collection}::delete	/{collection}/{id}	Delete a {collection} entry.
GET	n	collection	{collection}::read	/{collection}	Returns a list of {collection}.

Web Application Routes

Request Method	ID	Action	Resulting Function	Permission Required	URL Example	Notes
GET	n	create	create_form	{collection}::create	/{collection}/create	Displays a standard web form for submission to POST /{collection}.
GET	y	update	update_form	{collection}::update	/{collection}/{id}/update	Show the script details with the option to update attributes using PATCH to /{collection}/{id}
GET	n	import	import_form	{collection}::create	/{collection}/import	Displays a standard web form for submission to POST /{collection}/import.
POST	n	import	import	{collection}::create	/{collection}/import	Import multiple {collection} using a CSV.

Sort

To sort by a database column, user "sort={attribute}". To reverse sort, insert a minus, thus "sort=-{attribute}".

sort=[-]{attribute}

Current

By default, only attributes with "current=y" are retrieved. To override this, set current as below.

current={y|n|all}

GroupBy

groupby={attribute}

Limit

When requesting JSON, by default no limit is set.

When requesting screen display, the limit is set to 1000 by default.

limit={int}

Offset

The offset is the count of devices you wish to return data from.

offset={int}

Properties

Requested properties should be in a comma-separated list. Properties should be fully qualified - ie, system.hostname (not just hostname).

properties=id,name,status

You can also specify properties using the below format.

properties=["id","name","status"]

Filter

To filter by a property value, use the property name. Operators that should precede the value are !=, >, >=, <, <=, 'like' and '!like'. If no operator is specified, the default is =. Properties should be fully qualified - ie, system.hostname (not just hostname).

{attribute}=[operator]{value}

End Points

All endpoints URLs are of the format http://{server}/omk/open-audit/{endpoint}

Devices

Type	Endpoint
GET	/devices	Return a collection of devices with the default set of columns from the system table (system.system_id, system.icon, system.man_type, system.hostname, system.domain, system.man_ip_address, system.man_description, system.man_os_family, system.man_status)
GET	/devices/{id}	Return an individual devices details.
GET	/devices?sub_resource={sub_resource name}	To return all items in a sub_resource for a collection of devices. If you wanted all software you would use http://{server}/open-audit/index.php/devices?sub_resource=software
GET	/devices/{id}?sub_resource={sub_resource name}	To return all items in a sub_resource for a specific device.
GET	/devices?sub_resource={sub_resource name}&sub_resource_id={sub_resource id}	To return a specific item in a sub_resource for a collection of devices - not especially useful. You would more likely use the below (request a sub_resource items from a specific device)
GET	/devices{id}?sub_resource={sub_resource name}&sub_resource_id={sub_resource id}	To return a specific sub_resource item for a specific device.
