Decryption Code Sample

items = [{

amount: 1100, 
quantity: 2, 
** if you want to put ' in json array, you can use this way to make a correct json format or you can replace ' and " characters in your product name before sending to Dinger gateway **
items = `[{\"name\":\"Dinger\\'s\",\"amount\": ${totalAmount},\"quantity\":\"1\"}]`;

data = {

encryptedPayload = Base64.getEncoder().encodeToString(encrypteDataWithRsa) 

(Remark: encryptedPayload must be URL Encoded) 

SecretKey <- from merchant portal  

HashValue = encrypt the payload with your secret key by hmac sha256
