**************
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"]}' \
   --form key='MY-HTTPS-API-PLAINTEXT-KEY'


   response:
   {
      "success": true,
      "data": {
         "global": {
               "facility": {
                  "all": {
                     "level": "info"
                  },
                  "protocols": {
                     "level": "debug"
                  }
               }
         }
      },
      "error": null
   }

if you just want the Value of a multi-valued node, use the ``returnValues``
operation.

For example, get the addresses of a ``dum0`` interface.

.. code-block:: none

   curl -k --location --request POST 'https://vyos/retrieve' \
   --form data='{"op": "returnValues", "path": ["interfaces","dummy","dum0","address"]}' \
   --form key='MY-HTTPS-API-PLAINTEXT-KEY'

   respone:
   {
      "success": true,
      "data": [
         "10.10.10.10/24",
         "10.10.10.11/24",
         "10.10.10.12/24"
      ],
      "error": null
   }

The API pushes every request to a session and commit it.
But some of VyOS components like DHCP and PPPoE Servers, IPSec, VXLAN, and
other tunnels require full configuration for commit. 
The endpoint will process multiple commands when you pass them as a list to
the ``data`` field.

.. code-block:: none

   curl -k --location --request POST 'https://vyos/configure' \
   --form data='[{"op": "set","path":["interfaces","vxlan","vxlan1","remote","203.0.113.99"]}, {"op": "set","path":["interfaces","vxlan","vxlan1","vni","1"]}]' \
   --form key='MY-HTTPS-API-PLAINTEXT-KEY'

   response:
   {
      "success": true,
      "data": null,
      "error": null
   }


/config-file
============

The endpoint ``/config-file`` is to save or load a configuration.

Save a running configuration to the startup configuration.
When you don't specify the file when saving, it saves to
``/config/config.boot``.

.. code-block:: none

   curl -k --location --request POST 'https://vyos/config-file' \
   --form data='{"op": "save"}' \
