Authentication

All endpoints only listen on HTTP POST requests and the API KEY must set as
``key`` in the formdata.

Below see one example for curl and one for python.
The rest of the documentation is reduced to curl.

.. code-block:: none

   curl --location --request POST 'https://vyos/retrieve' \
   --form data='{"op": "showConfig", "path": []}' \
   --form key='MY-HTTPS-API-PLAINTEXT-KEY'

.. code-block:: python

   import requests
   url = "https://vyos/retrieve"
   payload={'data': '{"op": "showConfig", "path": []}',
            'key': 'MY-HTTPS-API-PLAINTEXT-KEY'
           }
   headers = {}
   response = requests.request("POST", url, headers=headers, data=payload)
   print(response.text)

/retrieve
=========

With the ``retrieve`` endpoint you get parts or the whole configuration.

To get the whole configuration, pass an empty list to the ``path`` field 

.. code-block:: none

   curl --location --request POST 'https://vyos/retrieve' \
   --form data='{"op": "showConfig", "path": []}' \
   --form key='MY-HTTPS-API-PLAINTEXT-KEY'


   response (shorted)
   {
      "success": true,
      "data": {
         "interfaces": {
               "ethernet": {
                  "eth0": {
                     "address": "dhcp",
                     "duplex": "auto",
                     "hw-id": "50:00:00:01:00:00",
                     "speed": "auto"
                  },
                  "eth1": {
                     "duplex": "auto",
                     "hw-id": "50:00:00:01:00:01",
                     "speed": "auto"
      ...
      },
      "error": null
   }


To only get a part of the configuration, for example ``system syslog``.

.. code-block:: none

   curl -k --location --request POST 'https://vyos/retrieve' \
   --form data='{"op": "showConfig", "path": ["system", "syslog"]}' \

                  "all": {
                     "level": "info"
                  },
                  "protocols": {
                     "level": "debug"
                  }

other tunnels require full configuration for commit. 
The endpoint will process multiple commands when you pass them as a list to
the ``data`` field.
