The old 'do it alone' approach is no longer applicable in today's IT environment. Applications and platforms need to work together in order to meet the needs of organizations. For this reason, the ability to integrate JIRA with other applications has become ever more important.

You can integrate applications with JIRA in many ways. JIRA itself comes with support to integrate with other Atlassian applications and a number of other popular Software as a Service (SaaS) applications, such as GitHub. Other than the integration supported out of the box, there are also many third-party add-ons that provide integration with applications and platforms such as Google Drive. And lastly, there is webhooks, a relatively new approach which allows any other application to register with JIRA for callbacks when certain events occur.
