Authorization

Please ensure that your authorization header follows the format below, including the required PHT prefix. This prefix ensures that the correct authorization rules are applied to your request.

Authorization: PHT apikey={{api_key}},signature={{signature}},timestamp={{timestamp}}

Description:

api_key: Application ID
shared_secret: Secret key
Authorization logic: The signature is generated by concatenating api_key, shared_secret, and the current Unix timestamp, then applying a SHA-512 hash.

⚠️ Important: The timestamp value must be exactly the same as the one used to generate the signature. If the values differ, the system will not be able to validate your signature, and the request will be rejected.

JAVA

 public static String getAuthorization(String apiKey, String secret) {
    Date date = new Date();
    long timestamp = (date.getTime() / 1000);
    String signature = null;
    try
    {
        String toBeHashed = apiKey + secret + timestamp;
        MessageDigest md = MessageDigest.getInstance("SHA-512");
        byte[] bytes = md.digest(toBeHashed.getBytes(StandardCharsets.UTF_8));
        StringBuilder sb = new StringBuilder();
        for (byte aByte : bytes)
        {
            sb.append(Integer.toString((aByte & 0xff) + 0x100, 16).substring(config.js));
        }
        signature = sb.toString();
    } catch (NoSuchAlgorithmException e)
    {
        e.printStackTrace();
    }
    String authHeaderValue = "PHT apikey=" + apiKey + ",signature=" + signature + ",timestamp=" + timestamp;

    double unixTime = (int)unixTicks.TotalSeconds;
    var toBeHashed = apiKey + secret + unixTime;
    var bytes = System.Text.Encoding.UTF8.GetBytes(toBeHashed);
