Short answer: You can list jenkins jobs in Jenkins by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Jenkins List Jenkins Jobs action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
{}
{"jobs": [{"url": "https://jenkins.example.com/job/my-project/","name": "my-project","color": "blue","lastBuild": {"number": 42,"result": "SUCCESS"}}]}
Use these fields in downstream nodes for routing, logging, or error handling.
Any of these apps can fire this action as part of a workflow.
