how to post array of generic objects in retrofit

Question

I Have this JSON , needed it to post on the server , the problem how we send array of generic objects

  "items": [
            {
                "variant": {
                    "id": 48,
                    "quantity": "1"
                },
                "custom_form_data": {
                    "features": {
                        "delivery_email": "[email protected]",
                        "delivery_mobile": "+886970639636"
                    },
                    "customer_info": "TEST Han Customer Info"
                }
            }
        ],

this is the call

 items = arrayOf(
                        Variant(id = 48, quantity = "1"),
                        CustomFormData(features = Features("[email protected]", "+886970639636") ,customerInfo = "inof")
                    ),

Define a data class for that format, something like this:

data class Item (
   val variant: Variant,
   val custom_form_data: CustomFormData
)

And then in your retrofit ApiService interface definition:

interface ApiService {

   @POST('url')
   fun methodName(): List<Item>

}
