+Notification settings
+=====================
+
+Endpoints for reading and updating the current user's notification preferences, including delivery platform, granularity, schedule, reminders, and snoozing.
+
+Endpoints:
+
+- [Get notification settings](#get-notification-settings)
+- [Update notification settings](#update-notification-settings)
+- [Snooze notifications](#snooze-notifications)
+
+
+Get notification settings
+-------------------------
+
+* `GET /my/notifications/settings.json` will return the current user's notification settings.
+
+###### Example JSON Response
+<!-- START GET /my/notifications/settings.json -->
+```json
+{
+  "platform": "web_and_email",
+  "granularity": "everything",
+  "show_badge_counts": true,
+  "schedule_enabled": false,
+  "schedule": null,
+  "bundle_enabled": true,
+  "schedule_entries_reminders": true,
+  "due_assignments_reminders": true,
+  "state": "on"
+}
+```
+<!-- END GET /my/notifications/settings.json -->
+
+When `schedule_enabled` is `true`, the `schedule` object is included:
+
+```json
+{
+  "schedule_enabled": true,
+  "schedule": {
+    "start_hour": 9,
+    "end_hour": 17,
+    "work_days": [1, 2, 3, 4, 5]
+  }
+}
+```
+
+###### Copy as cURL
+
+```shell
+curl -s -H "Authorization: Bearer $ACCESS_TOKEN" https://3.basecampapi.com/$ACCOUNT_ID/my/notifications/settings.json
+```
+
+
+Update notification settings
+----------------------------
+
+* `PUT /my/notifications/settings.json` will update the current user's notification settings. Only the provided parameters are changed; omitted parameters remain unchanged. Returns `204 No Content` on success.
+
+_Optional parameters_:
+
+* `platform` - delivery platform. Valid options: `web`, `email`, `web_and_email`.
+* `granularity` - notification granularity. Valid options: `everything`, `pings_and_mentions`.
+* `show_badge_counts` - whether to show badge counts. JSON `true` or `false` (not strings).
+* `schedule_enabled` - whether the notification schedule is active. JSON `true` or `false` (not strings). When `true`, also provide `schedule`.
+* `schedule` - an object with `start_hour` (integer 0–23), `end_hour` (integer 0–23, must be greater than `start_hour`), and `work_days` (non-empty array of integers, 0=Sunday through 6=Saturday).
+* `bundle_enabled` - whether notification bundling is enabled. JSON `true` or `false` (not strings).
+* `reminders` - an array of reminder types to enable. Valid values: `schedule_entries`, `due_assignments`. Pass an empty array to disable all reminders. These correspond to the `schedule_entries_reminders` and `due_assignments_reminders` boolean fields in the GET response.
+
+Providing an invalid `platform` or `granularity` returns `422 Unprocessable Entity` with an error listing the valid options:
+
+```json
+{
+  "errors": ["Invalid platform 'carrier_pigeon'. Valid options: web, email, web_and_email"]
+}
+```
