Describes the API structure.
# <a name="api-structure">`Structure`</a> [`top`](#top)
## <a name="api-versioning">`Versioning`</a> [`top`](#top)
Versioning an API is a minefield which saw us looking at numerous options on how to do this. Paul wrote an excellent blog post which touches on this: http://blog.librenms.org/2014/09/restful-apis/
We have currently settled on using versioning within the API end point itself `/api/v0` . As the API itself is new and still in active development we also decided that v0 would be the best starting point to indicate it's in development.
## <a name="api-tokens">`Tokens`</a> [`top`](#top)
To access any of the token end points you will be required to authenticate using a token. Tokens can be created directly from within the LibreNMS web interface by going to `/api-access/` .
- Click on 'Create API access token'.
- Select the user you would like to generate the token for.
- Enter an optional description.
- Click Create API Token.
## <a name="api-end_points">`Endpoints`</a> [`top`](#top)
Whilst this documentation will describe and show examples of the end points, we've designed the API so you should be able to traverse through it without know any of the available API routes.
You can do this by first calling `/api/v0` :
```curl
curl -H 'X-Auth-Token: YOURAPITOKENHERE' https://librenms.org/api/v0
Output
{
"list_bgp": "https://librenms.org/api/v0/bgp",
...
"edit_rule": "https://librenms.org/api/v0/rules"
}
```
## <a name="api-input">`Input`</a> [`top`](#top)
Input to the API is done in three different ways, sometimes a combination two or three of these.
- Passing parameters via the api route. For example when obtaining a devices details you will pass the hostname of the device in the route: `/api/v0/devices/:hostname` .
- Passing parameters via the query string. For example you can list all devices on your install but limit the output to devices that are currently down: `/api/v0/devices?type=down`
- Passing data in via JSON, this will mainly be used when adding or updating information via the API, for instance adding a new device:
```curl
curl -X POST -d '{"hostname":"localhost.localdomain","version":"v1","community":"public"}'-H 'X-Auth-Token: YOURAPITOKENHERE' https://librenms.org/api/v0/devices
```
## <a name="api-output">`Output`</a> [`top`](#top)
Output from the API currently is via two output types.
- JSON Most API responses will output json. As show in the example for calling the API endpoint.
- PNG This is for when the request is for an image such as a graph for a switch port.
# <a name="api-endpoints">`Endpoints`</a> [`top`](#top)

- severity: The severity level the alert will be raised against, Ok, Warning, Critical.
- disabled: Whether the rule will be disabled or not, 0 = enabled, 1 = disabled
- count: This is how many polling runs before an alert will trigger and the frequency.
- delay: Delay is when to start alerting and how frequently. The value is stored in seconds but you can specify minutes, hours or days by doing 5 m, 5 h, 5 d for each one.
- mute: If mute is enabled then an alert will never be sent but will show up in the Web UI (true or false).

- invert: This would invert the rules check.
- name: This is the name of the rule and is mandatory.

### <a name="api-route-19">Function: `edit_rule`</a> [`top`](#top)
Edit an existing alert rule
Route: /api/v0/rules
-
Input (JSON):
- rule_id: You must specify the rule_id to edit an existing rule, if this is absent then a new rule will be created.
- device_id: This is either the device id or -1 for a global rule
- rule: The rule which should be in the format %entity $condition $value (i.e %devices.status != 0 for devices marked as down).
- severity: The severity level the alert will be raised against, Ok, Warning, Critical.
- disabled: Whether the rule will be disabled or not, 0 = enabled, 1 = disabled
- count: This is how many polling runs before an alert will trigger and the frequency.
- delay: Delay is when to start alerting and how frequently. The value is stored in seconds but you can specify minutes, hours or days by doing 5 m, 5 h, 5 d for each one.

## <a name="api-inventory">`Inventory`</a> [`top`](#top)
### <a name="api-route-20">Function: `get_inventory`</a> [`top`](#top)
Retrieve the inventory for a device. If you call this without any parameters then you will only get part of the inventory. This is because a lot of devices nest each component, for instance you may initially have the chassis, within this the ports - 1 being an sfp cage, then the sfp itself. The way this API call is designed is to enable a recursive lookup. The first call will retrieve the root entry, included within this response will be entPhysicalIndex, you can then call for entPhysicalContainedIn which will then return the next layer of results.
Route: /api/v0/inventory/:hostname
- hostname can be either the device hostname or the device id
Input:
- entPhysicalClass: This is used to restrict the class of the inventory, for example you can specify chassis to only return items in the inventory that are labelled as chassis.
- entPhysicalContainedIn: This is used to retrieve items within the inventory assigned to a previous component, for example specifying the chassis (entPhysicalIndex) will retrieve all items where the chassis is the parent.
Example:
```curl
curl -H 'X-Auth-Token: YOURAPITOKENHERE' https://librenms.org/api/v0/inventory/localhost?entPhysicalContainedIn=65536
```
