JIRA platform

This documentation is for JIRA Server.
If you are using JIRA Cloud, see this documentation instead: JIRA Cloud development platform.

Every JIRA application (JIRA Software, JIRA Service Desk, JIRA Core) is built on the JIRA platform. The JIRA platform provides a set of base functionality that is shared across all JIRA applications, like issues, workflows, search, email, and more. You can extend and modify this functionality via the integration points provided by the JIRA platform, including the JIRA REST APIs, webhooks, plugin modules, etc.

The pages in this section will help you learn about the JIRA platform and how to develop for it. You'll find information on JIRA's architecture and JIRA add-ons, guides to developing for different parts of JIRA, JIRA Data Centre, and more.
