How to pass header in GET request

Here is an example:

client := &http.Client{}
apiURL := "https://myapi.url/data"
req, err := http.NewRequest("GET", apiURL, nil)
if err != nil {
	return nil, err
}

// add header to request
req.Header.Add("authkey", "...")

// perform get request
res, err := client.Do(req)

You dont need the else since your os.Exit'ing on condition of Line 12

@R4wm, done.
