Code:
const preparePayload = ({ crypto, config }, payload) => {
  let stringifiedPayload = JSON.stringify(payload);

  if (config.cipherKey) {
    stringifiedPayload = crypto.encrypt(stringifiedPayload);
    stringifiedPayload = JSON.stringify(stringifiedPayload);
  }

  return stringifiedPayload || '';
