+### Booking No-show Updated webhook payload
+
+This webhook is triggered when an attendee is manually marked or unmarked as no-show on the `/bookings/past` page.
+
+**Example payload when marking an attendee as no-show:**
+
+```json
+{
+  "triggerEvent": "BOOKING_NO_SHOW_UPDATED",
+  "createdAt": "2025-12-01T12:34:34.774Z",
+  "payload": {
+    "message": "[email protected] marked as no-show",
+    "attendees": [
+      {
+        "email": "[email protected]",
+        "noShow": true
+      }
+    ],
+    "bookingUid": "5vQFqxDFMjdgKGMijqtqRw",
+    "bookingId": 31
+  }
+}
+```
+
+**Example payload when unmarking an attendee as no-show:**
+
+```json
+{
+  "triggerEvent": "BOOKING_NO_SHOW_UPDATED",
+  "createdAt": "2025-12-01T12:38:31.663Z",
+  "payload": {
+    "message": "[email protected] unmarked as no-show",
+    "attendees": [
+      {
+        "email": "[email protected]",
+        "noShow": false
+      }
+    ],
+    "bookingUid": "5vQFqxDFMjdgKGMijqtqRw",
+    "bookingId": 31
+  }
+}
+```
+
+### Cal Video No-Show Detection webhooks
+
+These webhooks are triggered **automatically** when hosts or guests don't join a Cal Video meeting within the configured time after the booking starts. Unlike `BOOKING_NO_SHOW_UPDATED` which requires manual action, these are detected automatically by checking Cal Video participant data.
+
+<Note>
+These webhooks only work for bookings that use Cal Video as the meeting location.
+</Note>
+
+**Example payload when host didn't join (`AFTER_HOSTS_CAL_VIDEO_NO_SHOW`):**
+
+```json
