Recently I faced throttling issue and based on below article we should decorate request with User Agent


For all of our calls we use ExecuteQueryRetry which is PnP extension method. Based on my research and below article PnP addes Default Value("NONISV|SharePointPnP|PnPCore/{PnP CSOM Core assemblyversion}") for User Agent.


I tried to look around but couldn't find any documentation that PnP adds this value.

  • Can someone help me finding documentation about default value for User Agent if we use PnP CSOM?
  • Also I was wondering if passing this value will not result in Throttling ? or it can still happen?
  • What benefit we can get if we have user agent value ? Speed or Throttling or both?
