Yes, because you need to authenticate using credentials or a token... This is something that's missing apparently in the documentation (I'll make sure we fix it). In your code, you'll need to do something like the following:
` import requests
from requests.auth import HTTPBasicAuth

key = "<credential key for the user>"
secret = "<credential decreto fro the user>"

request_body = {
'ids': task_ids,
'status_reason': 'Tasks being spawned out of control'
}
url = ' '
x = requests.post(url, auth=HTTPBasicAuth(key, secret), json=request_body)
print(x) `
