facing issue while creating request format to call api

Hi All,

Below code is my request format expected by api

{

utilityProductMatch(sites: [

{

utilityId: "96d83432",

constraints: [

"Commercial"

products: [

{

productId: YZZ

existingProductCategory: "test",

equivalentWatts: 500,

operatingHours: 1800,

fixtureType: "test1"

}

]

}

])

{

utilityId

}

currently i created request format is below, now i m not able to understand how i can i append my below request on "utilityProductMatch" as mention in above.

{

"sites": [

{

"utilityId": "19dbc535a",

"constraints": {

"commercial": true

"products": [

{

"productId": "XYZ",

"existingProductCategory": "test",

"equivalentWatts": 500,

"operatingHours": "1800",

"FixtureType": "Lamp"

}

]

}

]

}

my classes are below to create current request format

public class GetCreateRequest
{
public List sites { get; set; }
}
public class Site
{
public string utilityId { get; set; }
public ProgramConstraints constraints { get; set; }
public List products { get; set; }
}
public class ProgramConstraints
{
public bool commercial
{
get;
set;
}
}
public class Product
{
public string productId { get; set; }
public string existingProductCategory { get; set; }
public int equivalentWatts { get; set; }
public string operatingHours { get; set; }
public string FixtureType { get; set; }
}

please suggest where i need to change in existing request format, so i will create request format as api expected.
