Download multiple Power Bi reports

Hi, lishapruthi ;
You could use REST  API  to  Download multiple Power Bi reports.

Export Power BI report to file API (preview) allows you to export Power BI reports to the following file formats: PDF, PPTX (PowerPoint) and PNG, by using a REST call. Since this API was launched, we had to impose a few limitations which we are removing now for Premium/Embedded Gen2 capacities. The following modifications apply:

• The number of Power BI exports per hour is not limited to 50 per hour per capacity, but only to 50 report pages per minute per capacity.
• There is no maximum concurrent report pages limitation.
• An export API operation load is evaluated as a slow-running/background operation as described in Premium Gen2 capacity load evaluation. The workload under which export API operations appears is called ‘InteractiveReportExports’.

We expect this Export Power BI report to file API to become GA by the end of December 2021.
