Made some progress and I can now connect and open a customer both in Postman and my .Net App however if I try and list customers I get "Your current role does not have permission to perform this action". The login audit report from the request shows "Success" I am using the same user and role I have used for SOAP which can list customers fine. In the role permissions I have enabled Lists > Customers (Full) as well as Setup REST Web Services (Full). If I log in with the same user in the UI I can list customers fine. I have confirmed I have the same problem loading and inboundshipment vs listing them. Can anybody point me at what permission it is that I would be missing on the role resulting that I can load an individual records but not list them? Thanks in advance.

Thanks. I hadn't realised the importance of SuiteAnalytics Workbook (because we aren't using SuiteAnalytics). Poorly named but apparently what we needed. Thanks
