unfortunately the documentation is lacking

I have the following example using go

// makeHmac:
//    non-exportable helper to do SHA256 HMAC
func makeHmac(data string, key string) string {
    byteKey, _ := hex.DecodeString(key)
    byteData := []byte(data)
    sig := hmac.New(sha256.New, byteKey)
    sig.Write([]byte(byteData))
    return base64.StdEncoding.EncodeToString(sig.Sum(nil))
}

[download]

still none the wiser though!

I do know that the app key provided should be treated as 32 2 byte values and not 64 1 byte values

Its this handling of the 32 2 byte values I am unsure of

thanks again for responding, its driving me slightly mad
