 ## 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 during these events:
 1) Always during a notification event.
 2) (optional) If `API_RUN` is set to `schedule` on a specified cron-like schedule specified by the `API_RUN_SCHD` setting.
 3) (optional) If `API_RUN` is set to `interval` every N seconds specified by the `API_RUN_INTERVAL` setting (minimum 5).
 ### 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](https://github.com/jokob-sk/Pi.Alert/blob/main/back/webhook_json_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](https://github.com/jokob-sk/Pi.Alert/tree/main/pholus) (A multicast DNS and DNS Service Discovery Security Assessment Tool) scan results. |
  | `table_events_pending_alert.json` | The list of the unprocessed (pending) notification events. |
  | `table_custom_endpoint.json` | A custom endpoint generated by the SQL query specified by the `API_CUSTOM_SQL` setting. |
  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:
 ```JSON
 {
  "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):
 ```JSON
 {
  "data": [
        {
          "dev_MAC": "Internet",

 ## How to setup your Network page
 Make sure you have a root device with the MAC `Internet` (No other MAC addresses are currently support as root)
 To setup a device named `rapberrypi` as a `Switch` in our network. 
 ### 1) Device details page
 - Go to the `Devices` (1) page:
 ![Device details](/docs/img/NETWORK_TREE/Device_Details_Network_Type.png)
 - In the (2) `Details` tab navigate to the the `Type` (3) dropdown and select the type `Switch` (4).
 > Note: Only the following device types will show up as selectable Network nodes ( = devices you can connect other devices to):
 > AP, Firewall, Gateway, PLC, Powerline, Router, Switch, USB LAN Adapter, USB WIFI Adapter and WLAN.
 - Assign a device to your root device from the `Node` (5) dropdown whitch has the MAC `Internet` (6) (Your name may differ, but the MAC needs to be set to `Internet` - this is done by default). 
 - Save your changes (7)
 ### 1) Network page
 - Navigate to your `Network` (1) page:
 ![Network page](/docs/img/NETWORK_TREE/Network_Page.png)
 - Notice the newly added `raspberrypi` (2) tab which now represents a network node, also showing up in the tree (3).
 - As we asssigned the `raspberrypi` in the previous 1) Device details page section to the `Internet` parent network node in step (6), the link is also showing up in the tree diagram (4)
 - We can now assign the device `(AppleTV)` (5) to this `raspberrypi` node, representing a network Switch in this example
 ### 1) Network page with 2 levels
 - After clicking the `Assign` button in the previous section, the `(AppleTV)` (1) device is now connected to our `raspberrypi` (2).
 ![Network page with 2 levels](/docs/img/NETWORK_TREE/Network_Page_2_Levels.png)
 - You can see the `raspberrypi` represents the Network node type `Switch` (3)
 - The `(AppleTV)` to `raspberrypi` connection is also displayed in the table of `Connected devices` (4).
 - You can also see that our `raspberrypi` node is connected to it's Parent network device node with the MAC `Internet` (5). This connection again shows up in the tree (6) as well.
