Access the REST API as a specific user rather than an overall system

[Beckah Sheeler]

So, right now, I am accessing the JIRA Rest API through my rails app.

If a user of my app wants change the "status" of an issue, I check to see if their associated JIRA user account is a member of groups with permissions to change that issue's status. 

For instance, if the JIRA username "Beckah" is part of the "jira-administrators" groups, they can change an issue's status from "In Progress" to "Complete".

My question is, is there a way to enforce these kinds of rules through Jira's rest API? In plain English, with a Rest PUT request, "User Beckah wants to move Issue NEM-11 to Complete" and see if it JIRA responds with an error or success based on Beckah's permissions to update that issue. 

Let me know if that makes any sense or if more details are needed.

You need to use oAuth instead of basic auth in your rails app. You also need to support user impersination. https://developer.atlassian.com/cloud/jira/platform/jira-rest-api-oauth-authentication/
