Deleting the decommissioned VMs from commvault using the rest api

I have to remove/Delete the VM from commvault using the Rest API

https://api.commvault.com/docs/api/cv/OpenAPI3/delete-virtual-machine

I have tried test running the api using python and I got the below mentioned error:

C:\Users\Ansible_user\Downloads>python vmdel.py WIN-C6TBRLJG6IM <commandcenter username> <commandcenter password

import requests
import urllib

#proxies={
	#'http':'http://10.***.***.***:8080',
	#'https':'http://10.***.***.***:8080'
#}
url = "https://win-c6tbrljg6im/commandcenter/api/V4/VirtualMachines/:<VM UUID>"

payload={}
headers = {
  'Accept': 'application/json',
  'Authtoken': '*******'
}

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

print(response.text)
