Can't get user properties using JIRA CLOUD REST API

[atlassian member]

Hi,

I'm trying to get user properties from their accountId using REST API, but I'm getting an unauthorized response.

{

    "code": 401,

    "message": "Unauthorized"

}

Here is the URL : https://api.atlassian.com/users/accountId/manage/profile and authorization is basic auth with the token I generated previously.

I can get fields from my cloud instance using the same API token, so the token is correct.

I can't find what's missing, any help would be much appreciated.

Thanks in advance.
