Jira Service Management: Third party (non-Atlassian) integrations
How do I develop custom integrations in Jira Service Management?
You can integrate Jira Service Management with almost any third-party system. To integrate with non-Atlassian applications, check the Marketplace for existing add-ons and connectors. If the one you're looking for does not exist, you can develop your own connectors. For any help with developing custom integration, you can ask questions at Atlassian Answers for community help.
We also have an extensive network of Atlassian Expert Partners who specialize in custom development and integrations, to build custom tools to fit your specific requirements. They would be the best resource to create your new custom integration should you not have such resources within your staff.
Server dev / test / staging environment:
To develop or test your custom integrations you can generate a developer license from your My Atlassian account. A developer license is available with any valid Atlassian commercial license. Its expiration will be the same as your valid commercial license. You can also use an evaluation license for testing, this license will, however, expire and need to be replaced every 30-days.
Cloud dev / test / staging environment:
Developer licenses are not available for Cloud subscriptions. To test your custom integrations in the Cloud, you'll need to spin up a free evaluation (7-days) or purchase a small, 10-user subscription for dev/staging/testing environment(s).
