I am trying to get each JSON object out of a JSON array. I get this data via a HTTP post.

I know what my data will look like:

          "entity_title":"University of Phoenix", 
          "entity_org_name":"CS Club",
          "possible_user_name":"Johnny Ive",
          "entity_title":"University of San Francisco", 
          "entity_org_name":"Marketing club",
          "possible_user_name":"steve jobs",

My example code and my structs look like this:

    type MsgCreateUserArray struct {
         CreateUser []MsgCreateUserJson `json:"createUserArray"`
    type MsgCreateUserJson struct {
        EntityTitleName string  `json:"entity_title_name"`
        EntityOrgName   string  `json:"entity_org_name"`
        PossibleUserName string `json:"possible_user_name"`
        PossibleUserEmail   string  `json:"possible_user_email"`
        UserPositionTitle   string  `json:"user_position_title"`
        MsgBodyId       string  `json:"msg_body_id, omitempty"` 

func parseJson(rw http.ResponseWriter, request *http.Request) {
    decodeJson := json.NewDecoder(request.Body)

    var msg MsgCreateUserArray
    err := decodeJson.Decode(&msg)

    if err != nil {

func main() {
    http.HandleFunc("/", parseJson)
    http.ListenAndServe(":1337", nil)

I am not sure where how to iterate over the JSON array and get the JSON objects and then just work with the JSON objects.

    Try this as your structs,

    type MsgCreateUserArray struct {
        CreateUser []MsgCreateUserJson `json:"array"`
    type MsgCreateUserJson struct {
        EntityOrgName     string  `json:"entity_org_name"`
        EntityTitle       string  `json:"entity_title"`
        MsgBodyID         int64   `json:"msg_body_id,omitempty"`
        PosibbleUserEmail string  `json:"posibble_user_email"`
        PossibleUserName  string  `json:"possible_user_name"`
        UserPositionTitle string  `json:"user_position_title"`

    Your entity_title_name is not named correctly, nor is the top level array. After you decode into a MsgCreateUserArray you can iterate over the CreateUser slice to get each MsgCreateUserJson
