I successfully managed to connect a java application to Power BI REST API and managed to create a dataset and added some data.
I can view this data from Power BI web interface, make reports, graph, etc.
Is it possible to connect Power BI Desktop to these datasets and create custom reports from there? I'm asking this because the desktop application seems to be more complete. You can edit column names, merge tables, etc. all things that are not available in the web application.
Thanks all for the help.
