We want to integrate our existing system to JIRA service desk cloud by allowing our existing users to create an issue from our web site without the need to login to JIRA customer portal. Our website has already a user login feature and what we want is when the user is already logged in to our custom web site they can go to customer portal without asking for a username and password. It is more like a single sign on. Is there a way to do this in JIRA cloud API?
