Custom Fields in Microsoft Bookings

Lobsang_aka ,

You will need to extract custom fields values using graph. You will need to filter with the following (use the exact same values). Then the returned value will need to be Base64 Decoded. I'm using this with Power Automate that start whenever a new event created (Outlook new event), extract the info and put into a SharePoint list.
