how to solve "{"message":"Client must be authenticated to access this resource.","status-code":401}"

I know that it was discussed before, but I don't see any solution for this error :

{"message":"Client must be authenticated to access this resource.","status-code":401}% 

I'm not working with UI ( User Interface) and I am working from backend, I want to authenticate myself (my users) to be able to run some API call.


I want to run this code :

curl --request GET \
--url '' \
--header 'Accept: application/json'

or in python :

import requests
import json
url = ""
headers = {
"Accept": "application/json"
response = requests.request(
print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))


But I'm getting this error :


{"message":"Client must be authenticated to access this resource.","status-code":401}% 


the question is how to authenticate it before or at same time (in same line) ?

Hi @Maziar Sojoudian ,

of course you are getting 401, there is no authentication header in your request.

I know you said username:password is not working anymore, but it does... so maybe you did something wrong.

Note that username:password need to be encoded in base64, so for example:

useradmin:passadmin = "dXNlcmFkbWluOnBhc3NhZG1pbg==" (and this is what you need to put in your authentication header).


You said you are working with python, so your request should be like that:

import requests

url = ""

payload = ""
headers = {
'Authorization': "Basic dXNlcmFkbWluOnBhc3NhZG1pbg=="

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

Hi Maziar


did you already have a look to the

there is explained how to use Basic Auth etc.

curl -u username:password -X GET -H "Content-Type: application/json" http://localhost:8080/rest/api/2/issue/createmeta



Hello Kurt,


Can I bind these two together ?


(And if you are not aware of that, (just saying) username:password is not working any more)

@Maziar Sojoudian 


Either you use username:password and if that does not work you can use a token based approach

I"m using the Basic authentication, but it looks like the response depends on the URL (i.e. the resource) I'm using..

Does anybody knows if I can use the same credentials I use to access Jira Service Desk or do I need to create a special user for API access?

Do I need to provide the user with special access privileges?

Does also the "expansion" of the JSON response depends on the user privileges?
