I am using WSDL recieved from Marketo to generate ip/op schemas. So for all parameters and its properties I refer to WSDL, but somehow this WSDL and Marketo Documentation is mismatched. In importToList API CampaignName is gives as Mandatory in WSDL but documentation says it is not Mandatory. Can someone please confirm which one should I follow? And can you make documentation and WSDL in sync, becuse as developer I always refer WSDL as contract to make SOAP request. But user of my product will refer to Marketo documentation to use API.
