Consume API using Server code

Question

I have been provided with an ajax API to read data from client PHP portal.

I have this code working:

    <!DOCTYPE HTML >
<html>
    <head>
        <title>Test</title> 
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script type="text/javascript"> 
                function runTest() {
                    var dataToSend = {
                        'format': 'XYZ-2.0',
                        'ops': {
                            resource: 'client-Read',
                            testOps: [
                                    {
                                        action: "Read",     
                                        resource: "client",
                                        value: {
                                            "fSalary": 50000,
                                            "fHomeMortgage": 400000,
                                            "aInsurance": {
                                                "coverLife": 155000
                                            },
                                            "aPersonalDetails": {
                                                "strName": "John Smith"
                                            }
                                        }
                                    }
                                    ]
                        }
                    };

                    jQuery.ajax(url+'/api/v3', {
                        type: 'POST',
                        data: JSON.stringify(dataToSend),
                        contentType: "application/json; charset=utf-8",
                        dataType: "jsonp",
                        success: function (data) {
                            alert(data);
                        },
                        error: function (xhr, ajaxOptions, thrownError) {
                            alert(xhr.status);
                            alert(thrownError);
                        }
                    });
                }
        </script>
    </head>
<body>
    <form id="form1">
        <input id="button1" type="button" OnClick="runTest();" value="Test">  </input>            
    </form>
</body>
</html>

How can I convert it to C#? in other words, how can I consume the same service using server side coding. the js array is confusing me.

Thanks

Use url: "PageName.aspx/FunctionName", in your ajax call.

 jQuery.ajax(url+'/api/v3', {
                    type: 'POST',
                    data: JSON.stringify(dataToSend),
                    contentType: "application/json; charset=utf-8",
                    dataType: "jsonp",
                    success: function (data) {
                        alert(data);
                    },
                    error: function (xhr, ajaxOptions, thrownError) {
                        alert(xhr.status);
                        alert(thrownError);
                    }
                });

Create a web method in code behind.

[WebMethod(EnableSession = false)]
public static string FunctionName(string data)
{
    // your businees logic
    return "abc";
}

I recommend that you use a library like the excellent RestSharp (http://restsharp.org/) library for interacting with your service from your C# code. RestSharp is Apache Licensed so it should be possible for you to use it even if your application is closed source.
