Label Manager REST API
For a general introduction to Jira's REST API and to find out about different Authentication Methods please read through the Official Atlassian Documentation for Jira's REST APIs.
We recommend you use the Atlassian REST API Browser to explore the API. Make sure you uncheck the option "Show only public APIs" and search for "labelit" .
