How can I make an OAuth request from my external application to any JIRA instance and make REST API calls?

Question

I have an external application(consumer of the API) that needs to make an authenticated request to any JIRA instance using OAuth and make REST API calls to obtain information from that instance. Setting up an application link allows me to create a link from my JIRA instance to an external application. I am trying to achieve the opposite. Is it possible to use Jira's REST API similar to that of Facebook or Twitter by creating a developer account and registering the consumer application to receive the consumer ID and secret? My question is similar to this.

Unfortunately the JIRA authentication documentation is not the best. I believe JIRA only supports OAuth1, so the authentication process will be slightly different from the other providers you mentioned.
