+## Redis Connection Settings
+
+[Redis](https://redis.io/) is a key-value store which functions as a very lightweight database. It is required when enabling NetBox [webhooks](../miscellaneous/webhooks/). A Redis connection is configured using a dictionary similar to the following:
+
+```
+REDIS = {
+    'HOST': 'localhost',
+    'PORT': 6379,
+    'PASSWORD': '',
+    'DATABASE': 0,

+
+### PORT
+
+Default: 6379
+
+The TCP port to use when connecting to the Redis server.

+
+The password to use when authenticating to the Redis server (optional).

 This section entails features of NetBox which are not crucial to its primary functions, but provide additional value.
 
+# Tags
+
+Tags are freeform labels which can be assigned to a variety of objects in NetBox. Tags can be used to categorize and filter objects in addition to built-in and custom fields. Each tag consists of a text label, as well as an auto-generated URL-friendly slug value. Objects can be filtered by the tags assigned to them. Tags can be used across different object types.
+
 # Custom Fields
 
 Each object in NetBox is represented in the database as a discrete table, and each attribute of an object exists as a column within its table. For example, sites are stored in the `dcim_site` table, which has columns named `name`, `facility`, `physical_address`, and so on. As new attributes are added to objects throughout the development of NetBox, tables are expanded to include new rows.
@@ -27,6 +31,10 @@ When a single object is edited, the form will include any custom fields which ha
 
 When editing multiple objects, custom field values are saved in bulk. There is no significant difference in overhead when saving a custom field value for 100 objects versus one object. However, the bulk operation must be performed separately for each custom field.
 
+# Contextual Configuration Data
+
+Sometimes it is desirable to associate arbitrary data with a group of devices to aid in their configuration. (For example, you might want to associate a set of syslog servers for all devices at a particular site.) Context data enables the association of arbitrary data (expressed in JSON format) to devices and virtual machines grouped by region, site, role, platform, and/or tenancy. Context data is arranged hierarchically, so that data with a higher weight can be entered to override more general lower-weight data. Multiple instances of data are automatically merged by NetBox to present a single dictionary for each object.

 # Export Templates
 
 NetBox allows users to define custom templates that can be used when exporting objects. To create an export template, navigate to Extras > Export Templates under the admin interface.

     If you experience a server error while attempting to upload an image attachment, verify that the system user NetBox runs as has write permission to the media root directory (`netbox/media/`).
+
+# 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.
+
+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.
+
+## Requests
+
+The webhook POST request is structured as so (assuming `application/json` as the Content-Type):
+
+```no-highlight
+{
+    "event": "created",
+    "signal_received_timestamp": 1508769597,
+    "model": "Site"
+    "data": {
+        ...
+    }
+}
+```
+
+`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:
+
+```no-highlight
+{
+    "event": "deleted",
+    "signal_received_timestamp": 1508781858.544069,
+    "model": "Site",
+    "data": {
+        "asn": None,
+        "comments": "",
+        "contact_email": "",
+        "contact_name": "",
+        "contact_phone": "",
+        "count_circuits": 0,
+        "count_devices": 0,
+        "count_prefixes": 0,
+        "count_racks": 0,
+        "count_vlans": 0,
+        "custom_fields": {},
+        "facility": "",

+        "name": "test",
+        "physical_address": "",
+        "region": None,
+        "shipping_address": "",
+        "slug": "test",
+        "tenant": None
+    }
+}
+```
+
+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/.
