Also, in 6.3, the API endpoint was different : [https://www.elastic.co/guide/en/elasticsearch/reference/6.3/security-api-put-user.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/security-api-put-user.html) But as @dadoonet said, do update to a recent version please ---

Do you have to work with kibana and elasticsearch in the same version? I can not pass if it is noon ☹ ---

You posted the docs page for version 7.9 while you are using version 6.3. I shared the docs page for version 6.3 that illustrates that you should be using a different API endpoint because back in 6.3, the endpoint was different. ---
