Thanks, Regards

You need only lining up your Go struct definitions with the JSON shape

Ex:
{
“id”: 123,
“name”: “Order #1”,
“customer”: {
“id”: 01,
“email”: “user@example.com”
}
}

In Go
type Order struct {
ID int json:"id"
Name string json:"name"
Customer Customer json:"customer"
}

type Customer struct {
	ID    int    `json:"id"`
	Email string `json:"email"`
}

then :
var order Order
err := json.Unmarshal(data, &order)

Yeah - I recommend Matt Holt’s json to go tool if you have JSON and want to product a corresponding struct:
