vCAC 6.1 API – Authentication

With the release of vCAC 6. 1(or rather vRealize Automation – that still takes some getting used to), the API which was in beta and a real pain to interact with in 6.0 has been made publicly available.

In order to interact with vRA 6.1, you first need to authenticate. Once you’ve authenticated and received your token, you then need to “stamp” every request with that token or your requests will be rejected. Examples of this will be provided with the examples in future posts.

Example 1.1 – Requesting a Token


Content-Type: application/json

Accept: application/json


POST https:///identity/api/tokens

Request Body:


Note: The values associated here are examples, insert the appropriate values for your environment.

If you are interacting with the API via RESTClient (or a similar plugin) you can add an additional header value of “Authorization: Bearer ” to future interactions. Note that the token will expire (I remember reading the default value for this, but appear to have misplaced the reference) so you shouldn’t hard code this token id anywhere.

Request Token

Add Authorization Header


If you prefer Python, then take a look at the following.

Example 1.2 – Requesting a Token with Python

from __future__ import unicode_literals
import requests, json

vcac_hostname = 'vcac.lab.local'
sa = 'administrator@vsphere.local’
sa_password= 'VMware1!'
default_tenant = 'vsphere.local'
headers = {'Content-Type' : 'application/json', 'Accept' : 'application/json’}
sa_auth_headers = {'Content-Type' : 'application/json', 'Accept' : 'application/json', 'Authorization': sa_token}

def token_for_username(sa):
    url = 'https://' + vcac_hostname + '/identity/api/tokens'
    data = {"username": sa,"password": sa_password,"tenant": default_tenant}
    req = = url, data = json.dumps(data), headers = headers, verify = False)
    commit_data = req.json()
    sa_token = 'Bearer ' + commit_data[u'id']
    if r.status_code != 200:
        print "Authentication Failed for " + sa + " with error text " + r.text
        print "Authentication Suceeded for " + sa + "."
        return sa_token

That’s it for authentication – short and sweet. Next up we’ll look at some Tenant creation and configuration examples.
