To facilitate your integration, in the following link you will find an HMAC-256 calculator. Please remember that the Tiemestamp has to be in epoch and should correspond to the UTC with a max. difference of +/- 5 minutes, a greater difference will be rejected. As per the Nonce, it should be a unique uuid that shall be unique per request. Due to the later, prior to sending a request it's mandatory to calculate a fresh timestamp and a new Nonce.

If you are not familiar with epoch time, you can read more about it here.
