I've configured OAuth on JIRA. How do I send it to login?

[Nicole Masarova]

Basically, for my personal application which I am publishing through GitHub, I have configured the OAuth on JIRA, to my application and it is working and operational through there. However, I want the website to send you to log in with JIRA when you submit a form. So far this is my code. I have been searching through a bunch of websites and these are the only three structures that I have found so far. None of them are working. Can anyone tell me what to do or how to structure it - or what the structure here means?

Thanks.

What do these mean? Are these right? Can they be inserted into html? I tried putting these as the action of the form tag. Sort of like this: 

<form action="(one of the links shown)"><other independant code></html>

1. http://example.com/auth
2. http:// ?response_type=code&
   client_id=CLIENT_ID&redirect_uri=REDIRECT_URI://callback&scope=SCOPE&state=KEY_SUPPLIED_BY_APPLICATION
3. http://example.com/auth/agile/1/session
