const token: PrivacyPassToken = {

  input: [

    22, 154, 58, 240, 238, 122, 125, 23, 99, 108, 170, 68, 67, 115, 3, 224, 100, 163, 56, 223,

// 2. Create redemption token header

const redemptionTokenHeader = getRedemptionHeader(

  token,

  'https://example.com/some/path',

);

// 3. Make a request with the redemtion token. The token is expired after use

const resp = await axios.get('https://example.com/some/path', { headers: redemptionTokenHeader });
