I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

You have mostly the right idea  it s just the sending of the form that is wrong  The form belongs in the body of the request   req  err    http NewRequest  POST   url  strings NewReader form Encode
