Welcome to the JIRA developer community!
- If you are using JIRA Cloud, head over to our new JIRA Cloud documentation and check out our Getting started with JIRA Cloud guide.
- If you are using JIRA Server, read our Getting started with Plugins2.
Note, the Atlassian Connect framework can only be used to build add-ons for Atlassian Cloud. If you want to build an add-on for JIRA server, read this guide on getting started with Plugins2 development. If you just want to integrate your existing application with JIRA remotely, head straight to the JIRA REST API docs .
