thank you for reaching out.
I'm not sure if Jira can connect with Power BI through REST API, however, it seems that Power BI already has a content pack that integrates with JIRA.
To connect to the JIRA content pack, simply choose JIRA from the list of available content packs. You will be asked to provide your JIRA URL and credentials. Once the connection has completed, Power BI will automatically create an out-of-the-box dashboard, report, and dataset with data from JIRA.
Please, check the documentation below to have more details on how you can configure the mentioned content pack and let me know if you have any questions:
