I am usin Azure ADB2C and with the API Graph GetUser I want also the extension properties I have configured on Azure Portal.
I've read that I should specify the field on the query string, but the field name is different from the one I chose, and it's something like "extension_GUID_fieldName".
The problem is that I can't get that name, i.e. retrieve the assigned GUID for that name; it seems no API lets you do that, and the only trick I've found is to query via PowerShell which is not a solution for me.
Any suggestion? Thanks
