Setup a connection between Hoowla and Powerbi

Integrate Hoowla with Power BI to enable full data extraction and reporting. Use the provided Hoowla API documentation to authenticate, retrieve all available endpoints and datasets, and implement efficient data ingestion into Power BI. Deliver a reusable, documented solution using Power Query (M), REST connectors, or a custom data connector as appropriate. Ensure incremental refresh capability, error handling, data transformation, and clear mapping of Hoowla fields to report-ready tables. Provide deployment and brief usage instructions.
