Error while browsing WebService

I'm trying to automate Sintegra's queries here at my company. I'm trying to implement in VB.NET (company software language), query through the webService made available by sefaz (

However, at the time of calling the service, passing the header and message, VS returns me the following error:

  

System.Web.Services.Protocols.SoapHeaderException: SOAP header Action   was not understood. at   System.Web.Services.Protocols.SoapHeaderHandling.SetHeaderMembers (SoapHeaderCollection   headers, Object target, SoapHeaderMapping [] mappings,   SoapHeaderDirection direction, Boolean client) at   System.Web.Services.Protocols.SoapServerProtocol.CreateServerInstance ()   at System.Web.Services.Protocols.WebServiceHandler.Invoke () at   System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest ()

I have already researched a number of forums about a solution. Until now, nothing.

To access web services via .NET follow these steps:

  • Right click on the project and select "Add Web References ..."
  • Enter the Web Service URL.

    • Now, just instantiate the Web Service object as an object and call the Web Services methods.

    From what I saw in your code, you are manually creating the Web Service call, which makes it very difficult to maintain the code.
