API endpoints

PiAlert comes with a simple API. These API endpoints are static files, that are periodically updated based on your settings.

When are the endpoints updated

Once you enable the API (ENABLE_API setting), the endpoints are updated when objects in the API endpoints are changed:

Location of the endpoints

In the container, these files are located under the /home/pi/pialert/front/api/ folder and thus on the <pialert_url>/api/<File name> url.

Available endpoints

You can access the following files:

File name	Description
notification_text.txt	The plain text version of the last notification.
notification_text.html	The full HTML of the last email notification.
notification_json_final.json	The json version of the last notification (e.g. used for webhooks - sample JSON).
table_devices.json	The current (at the time of the last update as mentioned above on this page) state of all of the available Devices detected by the app.
table_nmap_scan.json	The current state of the discovered ports by the regular NMAP scans.
table_pholus_scan.json	The latest state of the pholus (A multicast DNS and DNS Service Discovery Security Assessment Tool) scan results.
table_plugins_events.json	The list of the unprocessed (pending) notification events (plugins_events DB table).
table_plugins_history.json	The list of notification events history.
table_plugins_objects.json	The content of the plugins_objects table. Find more info on the Plugin system here
language_strings.json	The content of the language_strings table, which in turn is loaded from the plugins config.json definitions.
table_custom_endpoint.json	A custom endpoint generated by the SQL query specified by the API_CUSTOM_SQL setting.
table_settings.json	The content of the settings table.

Current/latest state of the aforementioned files depends on your settings.

JSON Data format

The endpoints starting with the table_ prefix contain most, if not all, data contained in the corresponding database table. The common format for those is:

{
  "data": [
        {
          "db_column_name": "data",
          "db_column_name2": "data2"      
        }, 
        {
          "db_column_name": "data3",
          "db_column_name2": "data4" 
        }
    ]
}

Example JSON of the table_devices.json endpoint with two Devices (database rows):
