How to integrate pay u biz integretion using MVC Ajax jquery

It seems like you are facing an issue with the hash generation while integrating the PayU Biz payment gateway. Here are some steps you can follow to resolve this issue:

1. Make sure that you have entered the correct merchant key and salt in the web.config file.

2. Check if the PayU Biz credentials you are using are for the test environment or the live environment. If you are testing, use the test credentials, and if you are ready for production, use the live credentials.

3. Verify if the hash generation logic is correct. You can use the following code to generate the hash:
    

   public static string GenerateHash(string text, string key)
   {
       byte[] messageBytes = Encoding.UTF8.GetBytes(text);
       byte[] keyBytes = Encoding.UTF8.GetBytes(key);
       string hashString = "";
   
       using (HMACSHA512 hmac = new HMACSHA512(keyBytes))
       {
           byte[] hashBytes = hmac.ComputeHash(messageBytes);
           hashString = BitConverter.ToString(hashBytes).Replace("-", "").ToLower();
       }
   
       return hashString;
   }
   

    

4. Make sure that you are passing all the required parameters for hash generation in the correct order. The hashSequence in the web.config file defines the order of the parameters for hash generation. Double-check that you have all the parameters in the correct order.

5. If the above steps do not resolve the issue, you can contact the PayU Biz support team for further assistance.

6. I hope this helps!
