go - JSON field set to null vs field not there

Question

Is there a way, in golang, to see if I can differentiate between a json field being set to null vs a json field not being there when unmarshalled into a struct? Because both set the value in the struct to be nil, but I need to know if the field was there to begin with and to see if someone set it to null.

{
  "somefield1":"somevalue1",
  "somefield2":null
}

VS

{
  "somefield1":"somevalue1",
}

Both jsons will be nil when unmarshalled into a struct. Any useful resources will be very appreciated!
