Hello! Have anybody ever used Postman or SoapUI for Netsuite SOAP API? I usually prefer Postman but for Netsuite it cannot read the WSDL correctly and despite it is quite easy to implement Token Based Authentication, the requests are a nightmare because they are all nearly empty.

people usually use postman here

One thought, have you looked into the REST web services, which are the newer version of SuiteTalk? There is no WSDL, but the API is documented and there is a sample collection for use with Postman to get started with it. Unless you are working on an application that requires SOAP for some reason, it’s worth trying newer REST integration.
