I am new to Jira and I am inheriting an application composed of an excel spreadsheet that is using a connector to query the mysql database behind Jira directly. Now, the database and Jira are going behind a firewall and the only access is to Jira behind a reverse proxy. I see that there is a plugin on the marketplace for a Jira connector; however, for reasons I won't go into I cannot use it. I was hoping that there is a way to issue a JQL query via the REST API; however, I didn't see any obvious support for this. I don't mind learning how to be a Jira developer, but I don't want to waste time if there is an easy solution. Any suggestions would be greatly appreciated!
