DEPOSIT REQUEST SIGNATURE🔒

🔐 How to Create a Signature Using MD5 Hashing
To create a sign using MD5 hashing, follow these steps:

   

 * 🔗 Concatenate the following values in this order, separated by the |
   character:
   
     
   
   * partner_code
   
     
   
   * secret
   
     
   
   * order_id
   
     
   
   * amount
   
     
   

 * 🧩 The resulting string should look like this:
   |partner_code|secret|order_id|amount|

   

 * ⚙️ Apply the MD5 hashing algorithm to the concatenated string.

   

Here’s how you can do it in different programming languages:

csharp


using System;
using System.Security.Cryptography;
using System.Text;
class Program {
    static void Main() {
        string partnerCode = "your_partner_code";
        string secret = "your_secret";
        string orderId = "your_order_id";
        string amount = "your_amount";
        string toHash = "|" + partnerCode + "|" + secret + "|" + orderId + "|" + amount + "|";
        using (MD5 md5 = MD5.Create()) {
            byte[] inputBytes = Encoding.UTF8.GetBytes(toHash);
            byte[] hashBytes = md5.ComputeHash(inputBytes);
            StringBuilder sb = new StringBuilder();
            foreach (byte b in hashBytes) {
                sb.Append(b.ToString("x2"));
            }
            Console.WriteLine(sb.ToString());
        }
    }
}

            StringBuilder sb = new StringBuilder();
            for (byte b : digest) {
                sb.append(String.format("x", b & 0xff));
            }
            System.out.println(sb.toString());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();

    }

DEPOSIT CALLBACK SIGNATURE🔒

🔐 To validate the callback signature, you need to generate a signature on your
end and compare it with the provided signature. Follow these steps:EndFragment

   

 * 🔗 Concatenate the following values in this order, separated by the |
   character:
   
     
   
   * partner_code
   
     
   
   * secret
   
     
   
   * ordID
   
     
   
   * amount
   
     
   
   * status
   
     
   
   * ranking ("-" if not available)
   
     
   

 * 🧩 The resulting string should look like this:
   |partner_code|secret|order_id|amount|status|ranking

   

 * ⚙️ Apply the MD5 hashing algorithm to the concatenated string.
