Hello, the app is really nice and works perfectly.

I am wondering that how I am able to put actual data from databases easily.

In the preparation, I found that you put header and data into structures and send them to web-block. 

It looks hard to customize when the size of entity is getting bigger.

For me, I have tried to use Json serialize, but this is not proper format as it looks like 

[{"Car":{"Id":5,"make":"Ford","Model":"Mondeo","Price":32000}}, 

Which shoud be 

[{"make":"Toyota","model":"Celica","price":35000},

If you already have an idea to solve, please help me.
