Organizations are adopting more and more IT applications, both on-premises and through cloud-based applications, in order to support their various business functions. As today's world is becoming more and more interconnected, these applications need to be similarly interlinked. Business functions often need to work together in order to achieve the desired outcome more efficiently. 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, both when reaching out to obtain data from other systems and when allowing other systems to access Jira's own data. Jira comes with support to integrate with other Atlassian applications and a number of other popular cloud applications, such as GitHub. Other than the integration supported out of the box, there are also many third-party apps that provide integration with applications and platforms such as Google Drive, Slack, and more. Lastly, there is webhook, a relatively new approach that allows any other application to register with Jira for callbacks when certain events occur.
