How to connect our Jira using nodejs
<p>I'm beginner in this territory! 
My question is how to connect to our Jira ( <a href="https://mycompany.atlassian.net" rel="nofollow noreferrer">https://mycompany.atlassian.net</a> (cloud)) for get all data from our jira projects (ex. user stories, tasks, issues ...).
 - I have access to admin jira !
 - I saw this: <a href="https://docs.atlassian.com/jira/REST/cloud/" rel="nofollow noreferrer">https://docs.atlassian.com/jira/REST/cloud/</a>
 - Should I have to buy an another licence for access to get data from api?</p>

<p>What are the first steps?     </p>
