How to get the sample code working?

I downloaded C%2523NET.zip from the examples and tried to run the project but then I keep getting the following problem:
The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was ''.

So I tried changing my basicHttpbinding to use basic in the following section of app.config:

But then I get a different error message:
The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was ''.

Any ideas on how to get started? I provided the credentials in ExactID field and Password. but that does not seem to work. Any help in that respect would be greatly appreciated. Thanks.

Jason - This is a probably an issue with the HMAC calculation. Here is a resource to help with HMAC - https://support.payeezy.com/hc/en-us/articles/203731149-API-Security-HMAC-Hash

If you are unable to resolve the issue, I would recommend reaching out to payeezy.gateway.support@firstdata.com.

Thank you for your quick response. This is the service reference that is included in the project:

https://api.globalgatewaye4.firstdata.com/transaction/wsdl

I was under the impression that version 12 onwards made HMAC a requirement but not before that. Perhaps I am mistaken!
