+
+# Send notifications to Gotify
+
+[Gotify](https://gotify.net/) is a self-hosted push notification service created for sending and receiving messages in real time.
+
+## Configuring Gotify
+
+### Prerequisites
+
+To use Gotify as your notification service, you need an application token. 
+You can generate a new token in the Gotify Web UI. 
+
+### Configuration
+
+To set up Gotify in Netdata: 
+
+1. Switch to your [config
+directory](/docs/configure/nodes.md) and edit the file `health_alarm_notify.conf` using the edit config script.
+ 
+   ```bash
+   ./edit-config health_alarm_notify.conf
+   ```
+
+2. Change the variable `GOTIFY_APP_TOKEN` to the application token you generated in the Gotify Web UI. Change
+`GOTIFY_APP_URL` to point to your Gotify instance.
+
+   ```conf
+   SEND_GOTIFY="YES"
+
+   # Application token
+   # Gotify instance url
+   GOTIFY_APP_TOKEN=XXXXXXXXXXXXXXX
+   GOTIFY_APP_URL=https://push.example.de/
+   ```
+
+   Changes to `health_alarm_notify.conf` do not require a Netdata restart. 
+   
+3. Test your Gotify notifications configuration by running the following commands, replacing `ROLE` with your preferred role:
+
+   ```sh
+   # become user netdata
+   sudo su -s /bin/bash netdata
+
+   # send a test alarm
+   /usr/libexec/netdata/plugins.d/alarm-notify.sh test ROLE
+   ```
+
+   🟢 If everything works, you'll see alarms in Gotify:
+
+   ![Example alarm notifications in Gotify](https://user-images.githubusercontent.com/103264516/162509205-1e88e5d9-96b6-4f7f-9426-182776158128.png)
+
+   🔴 If sending the test notifications fails, check `/var/log/netdata/error.log` to find the relevant error message:
+
+   ```log 
+   2020-09-03 23:07:00: alarm-notify.sh: ERROR: failed to send Gotify notification for: hades test.chart.test_alarm is CRITICAL, with HTTP error code 401.
+   ```
