+# Custom
+
+Netdata allows you to send custom notifications to any endpoint you choose.
+
+To configure custom notifications, you will need to customize `health_alarm_notify.conf`. You can look at the other senders in `/usr/libexec/netdata/plugins.d/alarm-notify.sh` for examples of how to modify the `custom_sender()` function in `health_alarm_notify.conf`. Ensure you follow the instructions of changing any configuration file to [persist your configuration](/docs/configuration-guide.md#persist-my-configuration).
+
+As with other notifications, you will also need to define the recipient list in `DEFAULT_RECIPIENT_CUSTOM` and/or the `role_recipients_custom` array.
+
+The following is a sample `custom_sender` function in `health_alarm_notify.conf`, to send an SMS via an imaginary HTTPS endpoint to the SMS gateway:
+
+```
+ custom_sender() {
+    # example human readable SMS
+    local msg="${host} ${status_message}: ${alarm} ${raised_for}"
+
+    # limit it to 160 characters and encode it for use in a URL
+    urlencode "${msg:0:160}" >/dev/null; msg="${REPLY}"
+
+    # a space separated list of the recipients to send alarms to
+    to="${1}"
+
+    for phone in ${to}; do
+      httpcode=$(docurl -X POST \
+				    --data-urlencode "From=XXX" \
+				    --data-urlencode "To=${phone}" \
+				    --data-urlencode "Body=${msg}" \
+				    -u "${accountsid}:${accounttoken}" \
+        https://domain.website.com/)
+
+       if [ "${httpcode}" = "200" ]; then
+         info "sent custom notification ${msg} to ${phone}"
+         sent=$((sent + 1))
+       else
+         error "failed to send custom notification ${msg} to ${phone} with HTTP error code ${httpcode}."
+       fi
+    done
+}
+```
+
+Variables available to the custom_sender:
+

+-   `${old_value}`          the previous value of the alarm
+-   `${src}`                the line number and file the alarm has been configured
+-   `${duration}`           the duration in seconds of the previous alarm state
+-   `${duration_txt}`       same as `${duration}` for humans
+-   `${non_clear_duration}` the total duration in seconds this is/was non-clear
+-   `${non_clear_duration_txt}` same as `${non_clear_duration}` for humans
+-   `${units}`              the units of the value
+-   `${info}`               a short description of the alarm

+-   `${total_critical}`     the total number of alarms in CRITICAL state on the host
+
+The following are more human friendly:
+
+-   `${alarm}`              like "name = value units"
+-   `${status_message}`     like "needs attention", "recovered", "is critical"
+-   `${severity}`           like "Escalated to CRITICAL", "Recovered from WARNING"
+-   `${raised_for}`         like "(alarm was raised for 10 minutes)"
