VyOS API

For configuration and enabling the API see HTTP-API

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.

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

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)

API Endpoints

/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

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.

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.

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
}

respone:
{
  "success": true,
  "data": "",
  "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.

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.

--form data='{"op": "save"}' \
--form key='MY-HTTPS-API-PLAINTEXT-KEY'
