The thing which we are going to learn is quite amazing cause making API’s is considered as one of the most difficult task and a lot of us are not able to make the desired applications cause we don’t have API’s or we are not able to make our own API’s for our services. But from now on, each and everything would be on your tips on How to make your own API using Windows Azure. So let’s start and first login to your Azure Account.

8Step 10: Now move back to Azure portal click on the database you created and there click View SQL Database connection strings.

9Step 11: After clicking the View SQL Database connection strings copy the ADO.Net connection string. Dont forget to enable firewall rules for your system.

10Step 12:  Open Microsoft Visual Studio 2013 (Note: Update 2 or higher required) and Create an Empty ASP.NET Empty Web Application Project.

11Step 13: After the project is open Right Click on references and then Click on Manage Nuget Packages. After that install Json.net.

12Step 14: Add a new class to the project name it as Connection and add following code to it.

13Step 15: After that add another class I have named it just Classes.cs and add code according to your requirement as here in the picture below.

14Step 16: Add the following code after the Classes class.

public class ClassesData

{

public List<Classes> ListofData = new List<Classes>();

}

Step 17: Add a new WebForm to the project and Delete all the text in the WebForm.aspx file except the first line as shown below.

15Step 18:  Now add the following code in Webform.aspx.cs file and then run it.

ClassesData data = new ClassesData();

        string key = null;

        protected void Page_Load(object sender, EventArgs e)

        {

            key = Request["key"];

            if (key == "yourapikey")

            {

                Load();

            }

            else

            {

                data.ListofData = null;

                Response.Write(JsonConvert.SerializeObject(data));

            }

        }

        public void Load()

        {

            SqlConnection connection = new SqlConnection(Connection.ConnectionString);

            try

            {

                connection.Open();

                SqlCommand readcommand = new SqlCommand("SELECT * FROM Sample", connection);

                SqlDataReader reader = readcommand.ExecuteReader();

                if (reader.HasRows)

                {

                    while (reader.Read())

                    {

                        data.ListofData.Add(new Classes(Convert.ToInt32(reader["ID"].ToString()), reader["name"].ToString(), reader["age"].ToString()));

                    }

                    Response.Write(JsonConvert.SerializeObject(data));

                }

                else

                {

                    data.ListofData = null;

                    Response.Write(JsonConvert.SerializeObject(data));

                }

                reader.Close();

                connection.Close();

            }

            catch (Exception ex)

            {

                data.ListofData = null;

                Response.Write(JsonConvert.SerializeObject(data));

            }

        }

 

 

Step 19: Something like that would happen as shown below.

16Step 20: You missed one thing, in the url above give your api key like shown below.

17Now you have your own API’s to work with and now you can make your own API’s really quick.

Isn’t it amazing you can now make API’s for your own services or you can make API’s for different firms in no time and charge them as much as you want cause making API’s is one of the most difficult task. Larger Organizations have separate departments who just work on their API’s.
