400 Bad Request when Exporting

[Anonymous]

I am trying to export a report using Postman. I have my Bearer token set, my Body is set like this:

{
format: "CSV"
}

and my URL looks like this (edited my reportId here for info)

https://api.powerbi.com/v1.0/myorg/reports/reportId/ExportTo

Try your call in the Power BI Rest API sandbox

Reports - Export To File - REST API (Power BI Power BI REST APIs) | Microsoft Docs

click the "Try it" button. You will notice that CSV is only supported for paginated reports.
