+# Webhook URLs
+
+BareRTC supports setting up webhook URLs so the chat server can call out to _your_ website in response to certain events, such as allowing users to send you reports about messages they receive on chat.
+
+Webhooks are configured in your settings.toml file and look like so:
+
+```toml
+[[WebhookURLs]]
+  Name = "report"
+  Enabled = true
+  URL = "http://localhost:8080/v1/barertc/report"
+```
+
+All Webhooks will be called as **POST** requests and will contain a JSON payload that will always have the following two keys:
+
+* `Action` will be the name of the webhook (e.g. "report")
+* `APIKey` will be your AdminAPIKey as configure in the settings.toml (shared secret so your web app can authenticate BareRTC's webhooks).
+
+The JSON payload may also contain a relevant object per the Action -- see the specific examples below.
+
+## Report Webhook
+
+Enabling this webhook will cause BareRTC to display a red "Report" flag button underneath user messages on chat so that they can report problematic messages to your website.
+
+The webhook name for your settings.toml is "report"
+
+Example JSON payload posted to the webhook:
+
+```javascript
+{
+    "Action": "report",
+    "APIKey": "shared secret from settings.toml#AdminAPIKey",
+    "Report": {
+        "FromUsername": "sender",
+        "AboutUsername": "user being reported on",
+        "Channel": "lobby",  // or "@username" for DM threads
+        "Timestamp": "(stringified timestamp of chat message)",
+        "Reason": "It's spam",
+        "Comment": "custom user note about the report",
+        "Message": "the actual message that was being reported on",
+    }
+}
+```
+
+BareRTC expects your webhook URL to return a 200 OK status code or it will surface an error in chat to the reporter.

 # Tour of the Codebase
 
 This app uses WebSockets and WebRTC at the very simplest levels, without using a framework like `Socket.io`. Here is a tour of the codebase with the more interesting modules listed first.
