 # Webhooks
 
-A webhook defines an HTTP request that is sent to an external application when certain types of objects are created, updated, and/or deleted in NetBox. When a webhook is triggered, a POST request is sent to its configured URL. This request will include a full representation of the object being modified for consumption by the receiver. Webhooks are configured via the admin UI under Extras > Webhooks.
+A webhook is a mechanism for conveying to some external system a change that took place in NetBox. For example, you may want to notify a monitoring system whenever a device status is changed in NetBox. This can be done by creating a webhook for the device model in NetBox. When NetBox detects a change to a device, an HTTP request containing the details of the change and who made it be sent to the specified receiver. Webhooks are configured in the admin UI under Extras > Webhooks.
 
-An optional secret key can be configured for each webhook. This will append a `X-Hook-Signature` header to the request, consisting of a HMAC (SHA-512) hex digest of the request body using the secret as the key. This digest can be used by the receiver to authenticate the request's content.
+## Configuration
 
-## Requests
+* **Name** - A unique name for the webhook. The name is not included with outbound messages.
+* **Object type(s)** - The type or types of NetBox object that will trigger the webhook.
+* **Enabled** - If unchecked, the webhook will be inactive.
+* **Events** - A webhook may trigger on any combination of create, update, and delete events. At least one event type must be selected.
+* **HTTP method** - The type of HTTP request to send. Options include GET, POST, PUT, PATCH, and DELETE.
+* **URL** - The fuly-qualified URL of the request to be sent. This may specify a destination port number if needed.
+* **HTTP content type** - The value of the request's `Content-Type` header. (Defaults to `application/json`)
+* **Additional headers** - Any additional headers to include with the request (optional). Add one header per line in the format `Name: Value`. Jinja2 templating is supported for this field (see below).
+* **Body template** - The content of the request being sent (optional). Jinja2 templating is supported for this field (see below). If blank, NetBox will populate the request body with a raw dump of the webhook context. (If the HTTP cotent type is set to `application/json`, this will be formatted as a JSON object.)
+* **Secret** - A secret string used to prove authenticity of the request (optional). This will append a `X-Hook-Signature` header to the request, consisting of a HMAC (SHA-512) hex digest of the request body using the secret as the key.
+* **SSL verification** - Uncheck this option to disable validation of the receiver's SSL certificate. (Disable with caution!)
+* **CA file path** - The file path to a particular certificate authority (CA) file to use when validating the receiver's SSL certificate (optional).
 
-The webhook POST request is structured as so (assuming `application/json` as the Content-Type):
+## Jinja2 Template Support
+
+[Jinja2 templating](https://jinja.palletsprojects.com/) is supported for the `additional_headers` and `body_template` fields. This enables the user to convey change data in the request headers as well as to craft a customized request body. Request content can be crafted to enable the direct interaction with external systems by ensuring the outgoing message is in a format the receiver expects and understands.
+
+For example, you might create a NetBox webhook to [trigger a Slack message](https://api.slack.com/messaging/webhooks) any time an IP address is created. You can accomplish this using the following configuration:
+
+* Object type: IPAM > IP address
+* HTTP method: POST
+* URL: <Slack incoming webhook URL>
+* HTTP content type: `application/json`
+* Body template: `{"text": "IP address {{ data['address'] }} was created by {{ username }}!"}`
+
+### Available Context
+
+The following data is available as context for Jinja2 templates:
+
+* `event` - The type of event which triggered the webhook: created, updated, or deleted.
+* `model` - The NetBox model which triggered the change.
+* `timestamp` - The time at which the event occurred (in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format).
+* `username` - The name of the user account associated with the change.
+* `request_id` - The unique request ID. This may be used to correlate multiple changes associated with a single request.
+* `data` - A serialized representation of the object _after_ the change was made. This is typically equivalent to the model's representation in NetBox's REST API.
+
+### Default Request Body
+
+If no body template is specified, the request body will be populated with a JSON object containing the context data. For example, a newly created site might appear as follows:
 
 ```no-highlight
 {
     "event": "created",
-    "timestamp": "2019-10-12 12:51:29.746944",
-    "username": "admin",
+    "timestamp": "2020-02-25 15:10:26.010582+00:00",
     "model": "site",
-    "request_id": "43d8e212-94c7-4f67-b544-0dcde4fc0f43",
+    "username": "jstretch",
+    "request_id": "fdbca812-3142-4783-b364-2e2bd5c16c6a",
     "data": {

+        "name": "Site 1",
+        "slug": "site-1",
+        "status":

+        },
+        "region": null,
         ...
     }
 }
 ```
 
-`data` is the serialized representation of the model instance(s) from the event. The same serializers from the NetBox API are used. So an example of the payload for a Site delete event would be:
+## Webhook Processing
 
-```no-highlight

-}
-```
+When a change is detected, any resulting webhooks are placed into a Redis queue for processing. This allows the user's request to complete without needing to wait for the outgoing webhook(s) to be processed. The webhooks are then extracted from the queue by the `rqworker` process and HTTP requests are sent to their respective destinations. The current webhook queue and any failed webhooks can be inspected in the admin UI under Django RQ > Queues.
 
-A request is considered successful if the response status code is any one of a list of "good" statuses defined in the [requests library](https://github.com/requests/requests/blob/205755834d34a8a6ecf2b0b5b2e9c3e6a7f4e4b6/requests/models.py#L688), otherwise the request is marked as having failed. The user may manually retry a failed request.
-
-## Backend Status
-
-Django-rq includes a status page in the admin site which can be used to view the result of processed webhooks and manually retry any failed webhooks. Access it from http://netbox.local/admin/webhook-backend-status/.
+A request is considered successful if the response has a 2XX status code; otherwise, the request is marked as having failed. Failed requests may be retried manually via the admin UI.

+# API Filtering
+
+The NetBox API supports robust filtering of results based on the fields of each model.
+Generally speaking you are able to filter based on the attributes (fields) present in
+the response body. Please note however that certain read-only or metadata fields are not
+filterable.
+
+Filtering is achieved by passing HTTP query parameters and the parameter name is the
+name of the field you wish to filter on and the value is the field value.
+
+E.g. filtering based on a device's name:
+```
+/api/dcim/devices/?name=DC-SPINE-1
+```
+
+## Multi Value Logic
+
+While you are able to filter based on an arbitrary number of fields, you are also able to
+pass multiple values for the same field. In most cases filtering on multiple values is
+implemented as a logical OR operation. A notible exception is the `tag` filter which
+is a logical AND. Passing multiple values for one field, can be combined with other fields.
+
+For example, filtering for devices with either the name of DC-SPINE-1 _or_ DC-LEAF-4:
+```
+/api/dcim/devices/?name=DC-SPINE-1&name=DC-LEAF-4
+```
+
+Filtering for devices with tag `router` and `customer-a` will return only devices with
+_both_ of those tags applied:
+```
+/api/dcim/devices/?tag=router&tag=customer-a
+```
+
+## Lookup Expressions
+
+Certain model fields also support filtering using additonal lookup expressions. This allows
+for negation and other context specific filtering.
+
+These lookup expressions can be applied by adding a suffix to the desired field's name.
+E.g. `mac_address__n`. In this case, the filter expression is for negation and it is seperated
+by two underscores. Below are the lookup expressions that are supported across different field
+types.
+
+### Numeric Fields
+
+Numeric based fields (ASN, VLAN ID, etc) support these lookup expressions:
+
+- `n` - not equal (negation)
+- `lt` - less than
+- `lte` - less than or equal
+- `gt` - greater than
+- `gte` - greater than or equal
+
+### String Fields
+
+String based (char) fields (Name, Address, etc) support these lookup expressions:
+
+- `n` - not equal (negation)
+- `ic` - case insensitive contains
+- `nic` - negated case insensitive contains
+- `isw` - case insensitive starts with
+- `nisw` - negated case insensitive starts with
+- `iew` - case insensitive ends with
+- `niew` - negated case insensitive ends with
+- `ie` - case sensitive exact match
+- `nie` - negated case sensitive exact match
+
+### Foreign Keys & Other Fields
+
+Certain other fields, namely foreign key relationships support just the negation
+expression: `n`.
