get keys from the interface

So as I just finished writing this question I figured out the map was the correct way to get my data.

Posted the question and answering it myself because I thought it would be useful for others

type Data struct {
        Devices map[int]interface{} `json:"devices" bson:"devices"`
}


for key, value := range deviceIds.Devices {
        fmt.Println(key, value)
}

Changing the struct to the above map and then looping through it with range worked perfectly
