Overload help method in WCF service

Question

for some reason I am asked to see if it possible to override the /help method of a service to return custom data instead. Currently I have a calling url like this one

http://{myDomain}/CRM/Customers.svc/json/help

Which returns all methods available

I tried something like this in my serviceContract, but I can't access to my method, is it possible ?

[WebInvoke(Method = "GET", UriTemplate = "/help", RequestFormat = WebMessageFormat.Json, 
                           ResponseFormat = WebMessageFormat.Json)]
void GetInformations();

Thanks

By default in web.config help page is enabled in the web http endpoint. To override it you could set as false, then your override method will be triggered.

  <webHttpEndpoint>
        <!-- TIP: Enable automatic XML/JSON support -->
        <!-- TIP: Enable service help page -->
        <standardEndpoint automaticFormatSelectionEnabled="true" helpEnabled="false"/>
      </webHttpEndpoint>

Thanks to @Balaji I dig a bit more and was able to make it work in a slightly different way. I applied a custom behaviorConfiguration to my service and in it I disabled the help, see below

<system.serviceModel>
    <services>
        <service behaviorConfiguration="ServiceBehavior" name="{myDomain}.CRM.Customers">
            <endpoint address="json" binding="webHttpBinding" behaviorConfiguration="JsonBehavior" bindingConfiguration="" contract="{contract}"/>
        </service>
    </services>
    <behaviors>
        <endpointBehaviors>
            <behavior name="JsonBehavior">
                <webHttp helpEnabled="false"/>
            </behavior>
       </endpointBehaviors>
    </behaviors>
</system.serviceModel>
