 ### Override global or controller antiforgery attributes
 
 The [IgnoreAntiforgeryToken](/dotnet/api/microsoft.aspnetcore.mvc.ignoreantiforgerytokenattribute) filter is used to eliminate the need for an antiforgery token for a given action (or controller). When applied, this filter overrides `ValidateAntiForgeryToken` and `AutoValidateAntiforgeryToken` filters specified at a higher level (globally or on a controller).
