How Can I create a restful application on C# in a project with A Soap application without getting a Bad Request 400 code?

Question

I've a Soap application which I want to replicate as a Rest

I've created the following code:

Interface:

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IRestfulCardServices" in both code and config file together.
[ServiceContract]
public interface IRestfulCardServices
{
    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json,
                                               BodyStyle = WebMessageBodyStyle.Bare,
                                               UriTemplate = "ConsultCards/")]
    List<CardInformation> ConsultCards();
}

Implementation:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class RestfulCardServices : IRestfulCardServices
{
    public List<CardInformation> ConsultCards()
    {
        return something;
    } 
}

Web.config

    </assemblyBinding>
  </runtime>
</configuration>

I keep getting a bad Request response as I call it on SoapUi/Postman. If I call the function directly from code behind it works fine. I think the problem might me because of the web config but the examples I've searched seem to be very similar to what I have presently

This is the response error I get:

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: { Cache-Control: private
Date: Mon, 05 Jun 2017 16:06:25 GMT Server: Microsoft-IIS/8.5
X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Content-Length: 0 }}

Any thought about what's missing?

Thanks in advance

Normally I get this kind of error when I give a wrong service name on the system.serviceModel config.

Check if:

<service name="ITSCredit.FlowCredit.Services.RestfulCardServices" behaviorConfiguration="serviceBehavior">

has the correct name (NameSpace.RestfulCardServices)
