  • Sandbox merchant number: Please contact the business development officer
  • Sandbox key: Please contact the business development officer
  • Production URL๏ผš Please contact the business development officer 
The information returned by the interface prioritizes determining whether the first
layer's request is successful, and only after the request is successful, the second
layer's transaction results could be checked

Signature Logic

  • 1๏ผšThe interface must report the sign parameter and the signing logic

Step 1: All requested parameters are judged from a to z according to the first letter of the parameter name, and combined into key1=value1key2=value2......

List<String> keys = Lists.newArrayList(map.keySet());
Collections.sort(keys);
StringBuilder request = new StringBuilder();
for (String key : keys) {
  String value = String.valueOf(map.get(key));
  if (StrUtil.isNotEmpty(value) && !"sign".equals(key)) {
    request.append(key).append("=").append(value);
  }
}
log.error("encrypt string : {}", request);

Step2๏ผšUse app secret as salt for md5 encryption.

Parameter Description
SIGN_TYPE MD5
CHARSET_NAME UTF-8
salt Private Key 
try {
  MessageDigest md5 = MessageDigest.getInstance(SIGN_TYPE);
  md5.update((str + salt).getBytes(CHARSET_NAME));
  return byte2hex(md5.digest());
} catch (Exception e) {
  if (log.isDebugEnabled()) {
    log.debug("md5 Encryption error", e);
  }
}
return "";


public static String byte2hex(byte\[\] bytes) {  
  StringBuilder sign = new StringBuilder();  
  for (int i = 0; i < bytes.length; i++) {  
    String hex = Integer.toHexString(bytes\[i\] & 0xFF);  
    if (hex.length() == 1) {  
      sign.append("0");  
    }  
    sign.append(hex.toLowerCase());  
  }  
  return sign.toString();  
}
- 2๏ผšThe requested merchant number is required to be added in the header submission. - 3๏ผšIP whitelists need to be added during the test. For this operation, please contact Vexora business development officer.
