Welcome to the Atlassian developer community @TomSvare, I’ve moved your post into Jira Server category. You might already be aware that Jira Server (and Data Center) REST APIs and Jira Cloud REST APIs have diverged over a number of years. Despite the tempting logic of “code reuse,” it is best to treat the 2 as distinct products with separate clients. Our [developer licensing options](https://developer.atlassian.com/developer-guide/cloud-and-data-center-for-developers/) tend toward existing customers (especially for Server/Data Center) and are a little out of date. Technically, the Server option is no longer available, only Data Center. Also, we’ve had some disruption to the availability of [product source code](https://community.developer.atlassian.com/t/what-happened-to-the-source-downloads/75492). Historically, the [Atlassian SDK](https://developer.atlassian.com/server/framework/atlassian-sdk/) has been the option available for software developers. While it was built around the needs for Java plugin development, it can be used to test REST APIs too. The dev licensing for the SDK is “time-bombed” where the SDK must be restarted every 3 days. I must caveat that I haven’t run the SDK myself in years, so even my understanding might be out of date. Also, it is a long-known fact that [the SDK is not well maintained](https://community.developer.atlassian.com/t/outdated-atlassian-sdk-and-amps/36504). Hopefully, that information and the caveats help you avoid some frustration. --- _[View the full topic](https://community.developer.atlassian.com/t/jira-server-rest-api/82923)._
