How do I consume this web service in a .NET app?

Question

I'm pushing the bounds of what one should ask of others with this one, but I'm totally stuck, so here goes...

This is my first web service. Not only that, it's my companies first web service - nobody I work with has ever written or consumed anything like this one. I know these things are not complicated, but for a first kick at the can, this is killing me because the API is so large.

WSDL is here: https://fast.uspspostalone.com/USPSMLXMLWeb/services/UspsMailXmlMailingServices/wsdl/UspsMailXmlMailing70.wsdl

I need to get a "FullServiceNixieDetail". Should be an XML doc. The documentation provided by USPS says I need to invoke FullServiceNixieDetailQueryRequest, and I will get back a FullServiceNixieDetailQueryResponse, which contains a FullServiceNixieDetail.

I cannot for the life of me get anything that seems to work. The code I currently have is:

Imports USPSACSProcessor.UPSPMailXML

Dim c As New UspsMailXmlMailingServiceClient
Dim request As New FullServiceNixieDetailQueryRequest
Dim response As FullServiceNixieDetailQueryResponse
'Assume I populate the Request object correctly here
response = c.FullServiceNixieDetailQuery(request)

But my response object has no FullServiceNixieDetail. Just a bunch of summary properties like TotalMessageCount etc.

How do I get my FullServiceNixieDetail XML?

Answer 1

Did you populate your request with the proper authentications?

I suspect it is the response.Item that is the FullServiceNixieDetail, but without the usage knowledge of this particular web service, it's hard to confirm, you will need to find this out from the service host. You can also try doing a cast on the item to FullServiceNixieDetail, to verify this.
