Getting started with Weka REST API

The Weka system supports a RESTful API. This is useful when automating the interaction with the Weka system and when integrating it into your workflows or monitoring systems.

The API is accessible at port 14000, via the /api/v2 URL, you can explore it via /api/v2/docs when accessing from the cluster (e.g. https://weka01:14000/api/v2/docs).

Our static API documentation can be accessed from api.docs.weka.io (the version can be selected from the drop-down list). The .json file can also be used to create your client code, using an OpenAPI client generator.

Obtain an access token

You must provide an access token to use the Weka REST API.

To obtain access/refresh tokens via the CLI, refer to Obtaining an Authentication Token section (there you can also generate an access token with a longer expiry time). To obtain access/refresh tokens via the API, you can call the login API, providing it a username and password.

If you already obtained a refresh token, you can use the login/refresh API to refresh the access token.

Login

Python example calling the login API

import requests

url = "https://weka01:14000/api/v2/login"

payload="{\n    \"username\": \"admin\",\n    \"password\": \"admin\"\n}"
headers = {
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

Refresh

Python example calling the login refresh API

import requests

url = "https://weka01:14000/api/v2/login/refresh"

payload="{\n    \"refresh_token\": \"REPLACE-WITH-REFRESH-TOKEN\"\n}"
headers = {
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

In response, you will get an access token (valid for 5 minutes), that can be used in the other APIs that require token authentication, along with the refresh token (valid for 1 year), for getting additional access tokens without using the username/password.

Login/Refresh Response

{
  "data": [
    {
      "access_token": "ACCESS-TOKEN",
      "token_type": "Bearer",
      "expires_in": 300,
      "refresh_token": "REFRESH-TOKEN"
    }
  ]
}

Call the REST API

Now, that you have obtained an access token, you can call Weka REST API commands with it. For example, you can query the cluster status:

Python example calling cluster status API

import requests

url = "https://weka01:14000/api/v2/cluster"

payload={}
headers = {
  'Authorization': 'Bearer REPLACE-WITH-ACCESS-TOKEN'
}

response = requests.request("GET", url, headers=headers, data=payload)

print(response.text)
