+### Notifications
+
+Currently, only webhook notification is available. Webhook sends a POST request to the specified endpoint in json format.
+
+Request body example:
+```json
+{
+  "old_ip": "xxx.xxx.xxx.xxx",
+  "new_ip": "xxx.xxx.xxx.xxx",
+  "checked_at": "2023-05-04T17:39:42.942850354+02:00",
+  "resolver_tag": "ifconfig.me",
+  "domain": "my.domain.com"
+}
+```
+
+Other notification methods will be implemented later (check future plans section).
