 NetBox v2.0 and later includes a full-featured REST API that allows its data model to be read and manipulated externally.
 
+# What is a REST API?
+
+REST stands for [representational state transfer](https://en.wikipedia.org/wiki/Representational_state_transfer). It's a particular type of API which employs HTTP to create, retrieve, update, and delete objects from a database. (This set of operations is commonly referred to as CRUD.) Each type of operation is associated with a particular HTTP verb:
+
+* `GET`: Retrieve an object or list of objects
+* `POST`: Create an object
+* `PUT` / `PATCH`: Modify an existing object. `PUT` requires all mandatory fields to be specified, while `PATCH` only expects the field that is being modified to be specified.
+* `DELETE`: Delete an existing object
+
+The NetBox API represents all objects in [JavaScript Object Notation (JSON)](http://www.json.org/). This makes it very easy to interact with NetBox data on the command line with common tools. For example, we can request an IP address from NetBox and output the JSON using `curl` and `jq`. (Piping the output through `jq` isn't strictly required but makes it much easier to read.)
+
+```
+$ curl -s http://localhost:8000/api/ipam/ip-addresses/2954/ | jq '.'
+{
+  "custom_fields": {},
+  "nat_outside": null,
+  "nat_inside": null,
+  "description": "An example IP address",
+  "id": 2954,
+  "family": 4,
+  "address": "5.101.108.132/26",
+  "vrf": null,
+  "tenant": null,
+  "status": {
+    "label": "Active",
+    "value": 1
+  },
+  "role": null,
+  "interface": null
+}
+```
+
+Each attribute of the NetBox object is expressed as a field in the dictionary. Fields may include their own nested objects, as in the case of the `status` field above. Every object includes a primary key named `id` which uniquely identifies it in the database.
+
 # URL Hierarchy
 
-NetBox's entire REST API is housed under the API root, `/api/`. The API's URL structure is divided at the root level by application: circuits, DCIM, extras, IPAM, secrets, and tenancy. Within each application, each model has its own path. For example, the provider and circuit objects are located under the "circuits" application:

When performing write api actions (`POST`, `PUT`, and `PATCH`), any `ForeignKey` relationships do not use the nested serializer, instead you will pass just the integer ID of the related model.  
 
 When a base serializer includes one or more nested serializers, the hierarchical structure precludes it from being used for write operations. Thus, a flat representation of an object may be provided using a writable serializer. This serializer includes only raw database values and is not typically used for retrieval, except as part of the response to the creation or updating of an object.

+## Static Choice Fields
+
+Some model fields, such as the `status` field in the above example, utilize static integers corresponding to static choices. The available choices can be retrieved from the read-only `_choices` endpoint within each app. A specific `model:field` tuple may optionally be specified in the URL.
+
+Each choice includes a human-friendly label and its corresponding numeric value. For example, `GET /api/ipam/_choices/prefix:status/` will return:
+
+```
+[
+    {
+        "value": 0,
+        "label": "Container"
+    },
+    {
+        "value": 1,
+        "label": "Active"
+    },
+    {
+        "value": 2,

+    },
+    {
+        "value": 3,
+        "label": "Deprecated"
+    }
+]
+```
+
+Thus, to set a prefix's status to "Reserved," it would be assigned the integer `2`.
+
+A request for `GET /api/ipam/_choices/` will return choices for _all_ fields belonging to models within the IPAM app.

+
+# Filtering
+
+A list of objects retrieved via the API can be filtered by passing one or more query parameters. The same parameters used by the web UI work for the API as well. For example, to return only prefixes with a status of "Active" (`1`):
+
+```
+GET /api/ipam/prefixes/?status=1
+```
+
+The same filter can be incldued multiple times. These will effect a logical OR and return objects matching any of the given values. For example, the following will return all active and reserved prefixes:
+
+```
+GET /api/ipam/prefixes/?status=1&status=2
+```
+
+## Custom Fields
+
+To filter on a custom field, prepend `cf_` to the field name. For example, the following query will return only sites where a custom field named `foo` is equal to 123:
+
+```
+GET /api/dcim/sites/?cf_foo=123
+```
+
+!!! note
+    Full versus partial matching when filtering is configurable per custom field. Filtering can be toggled (or disabled) for a custom field in the admin UI.

 Device types are instantiated as devices installed within racks. For example, you might define a device type to represent a Juniper EX4300-48T network switch with 48 Ethernet interfaces. You can then create multiple devices of this type named "switch1," "switch2," and so on. Each device will inherit the components (such as interfaces) of its device type.
 
+A device type can be a parent, child, or neither. Parent devices house child devices in device bays. This relationship is used to model things like blade servers, where child devices function independently but share physical resources like rack space and power. Note that this is **not** intended to model chassis-based devices, wherein child members share a common control plane.

Two special form factors exist: the "virtual" form factor can be used to designate logical interfaces (such as SVIs), and the "LAG" form factor can be used to desinate link aggregation groups to which physical interfaces can be assigned. Each interface can also be designated as management-only (for out-of-band management) and assigned a short description.
 
 Device bays represent the ability of a device to house child devices. For example, you might install four blade servers into a 2U chassis. The chassis would appear in the rack elevation as a 2U device with four device bays. Each server within it would be defined as a 0U device installed in one of the device bays. Child devices do not appear on rack elevations, but they are included in the "Non-Racked Devices" list within the rack view.

+# Virtual Chassis
+
+A virtual chassis represents a set of devices which share a single control plane: for example, a stack of switches which are managed as a single device. Each device in the virtual chassis is assigned a position and (optionally) a priority. Exactly one device is designated the virtual chassis master: This device will typically be assigned a name, secrets, services, and other attributes related to its management.
+
+It's important to recognize the distinction between a virtual chassis and a chassis-based device. For instance, a virtual chassis is not used to model a chassis switch with removable line cards such as the Juniper EX9208, as its line cards are _not_ physically separate devices capable of operating independently.

+# NetBox Reports
+
+A NetBox report is a mechanism for validating the integrity of data within NetBox. Running a report allows the user to verify that the objects defined within NetBox meet certain arbitrary conditions. For example, you can write reports to check that:
+
+* All top-of-rack switches have a console connection
+* Every router has a loopback interface with an IP address assigned
+* Each interface description conforms to a standard format
+* Every site has a minimum set of VLANs defined
+* All IP addresses have a parent prefix
+
+...and so on. Reports are completely customizable, so there's practically no limit to what you can test for.
+
+## Writing Reports
+
+Reports must be saved as files in the [`REPORTS_ROOT`](../configuration/optional-settings/#reports_root) path (which defaults to `netbox/reports/`). Each file created within this path is considered a separate module. Each module holds one or more reports (Python classes), each of which performs a certain function. The logic of each report is broken into discrete test methods, each of which applies a small portion of the logic comprising the overall test.
+
+!!! warning
+    The reports path includes a file named `__init__.py`, which registers the path as a Python module. Do not delete this file.
+
+For example, we can create a module named `devices.py` to hold all of our reports which pertain to devices in NetBox. Within that module, we might define several reports. Each report is defined as a Python class inheriting from `extras.reports.Report`.
+
+```
+from extras.reports import Report
+
+class DeviceConnectionsReport(Report):
+    description = "Validate the minimum physical connections for each device"
+
+class DeviceIPsReport(Report):
+    description = "Check that every device has a primary IP address assigned"
+```
+
+Within each report class, we'll create a number of test methods to execute our report's logic. In DeviceConnectionsReport, for instance, we want to ensure that every live device has a console connection, an out-of-band management connection, and two power connections.
+
+```
+from dcim.constants import CONNECTION_STATUS_PLANNED, DEVICE_STATUS_ACTIVE
+from dcim.models import ConsolePort, Device, PowerPort
+from extras.reports import Report
+
+
+class DeviceConnectionsReport(Report):
+    description = "Validate the minimum physical connections for each device"
+
+    def test_console_connection(self):
+
+        # Check that every console port for every active device has a connection defined.
+        for console_port in ConsolePort.objects.select_related('device').filter(device__status=DEVICE_STATUS_ACTIVE):
+            if console_port.cs_port is None:
+                self.log_failure(
+                    console_port.device,
+                    "No console connection defined for {}".format(console_port.name)
+                )
+            elif console_port.connection_status == CONNECTION_STATUS_PLANNED:

+            for power_port in PowerPort.objects.filter(device=device):

+                )
+            else:
+                self.log_success(device)
+```
+
+As you can see, reports are completely customizable. Validation logic can be as simple or as complex as needed.
+
+!!! warning
+    Reports should never alter data: If you find yourself using the `create()`, `save()`, `update()`, or `delete()` methods on objects within reports, stop and re-evaluate what you're trying to accomplish. Note that there are no safeguards against the accidental alteration or destruction of data.
+
+The following methods are available to log results within a report:
+
+* log(message)
+* log_success(object, message=None)
+* log_info(object, message)
+* log_warning(object, message)
+* log_failure(object, message)
+
+The recording of one or more failure messages will automatically flag a report as failed. It is advised to log a success for each object that is evaluated so that the results will reflect how many objects are being reported on. (The inclusion of a log message is optional for successes.) Messages recorded with `log()` will appear in a report's results but are not associated with a particular object or status.
+
+To perform additional tasks, such as sending an email or calling a webhook, after a report has been run, extend the `post_run()` method. The status of the report is available as `self.failed` and the results object is `self.result`.
+
+Once you have created a report, it will appear in the reports list. Initially, reports will have no results associated with them. To generate results, run the report.
+
+## Running Reports
+
+### Via the Web UI
+
+Reports can be run via the web UI by navigating to the report and clicking the "run report" button at top right. Note that a user must have permission to create ReportResults in order to run reports. (Permissions can be assigned through the admin UI.)
+
+Once a report has been run, its associated results will be included in the report view.
+
+### Via the API
+
+To run a report via the API, simply issue a POST request to its `run` endpoint. Reports are identified by their module and class name.
+
+```
+    POST /api/extras/reports/<module>.<name>/run/
+```
+
+Our example report above would be called as:
+
+```
+    POST /api/extras/reports/devices.DeviceConnectionsReport/run/
+```
+
+### Via the CLI
+
+Reports can be run on the CLI by invoking the management command:
+
+```
+python3 manage.py runreport <module>
+```
+
+One or more report modules may be specified.
