So you're going to develop something for JIRA Server (internally hosted software). You'll be using Plugins2* 1. Start here https://developer.atlassian.com/jiradev/getting-started/getting-started-with-plugins2 https://developer.atlassian.com/jiradev/getting-started/gett... 2. Install the SDK (it has some pre-reqs) and build Hello World https://developer.atlassian.com/docs/getting-started/set-up-the-atlassian-plugin-sdk-and-build-a-project https://developer.atlassian.com/docs/getting-started/set-up-... 3. Bone up on Plugins2 a bit more https://developer.atlassian.com/jiradev/jira-platform/building-jira-add-ons/jira-plugins2-overview https://developer.atlassian.com/jiradev/jira-platform/buildi... 4. API Reference https://developer.atlassian.com/jiradev/jira-apis https://developer.atlassian.com/jiradev/jira-apis (I recommend the REST APIs + Webhooks wherever possible). I'm really keen to talk with you about your experience going through that - there's a lot of history and we're aware we need to clean up the journey. _* If you were developing for JIRA Cloud you'd be using Atlassian Connect.
