I have written code in both Java and C# to call a web services method on a third party web site. I receive an "Invalid Request" response. I told the programmer for the web service that I thought I did everything right and got this response. He said to "Please send [him] the full request you are sending, header, body & timestamp and we’ll check the server log." How would you generally communicate this with somebody? I created the message in Java and C#, and he doesn't want my code snippet. Should I capture with wireshark, or is there a generally accepted method or some other convenient often use tool(s) that people use for this? Is this a reasonable request, or since nobody is using their web service but me yet, isn't it reasonable for me to just ask them to look at their logs?
