# Processing payment

These are the steps to be followed to process a payment.

# Payment object

Create the payment object with the parameters.

// Sample customer object
const customerObject = {
  UserName: "XXXXXX@paytriot.co.uk",
  CustomerName: "test",
  EmailID: "tester@test.com",
  Amount: 123.12,
  PhoneNumber: "+123123123123",
  Street: "Test",
  City: "London",
  Country: "United Kingdom",
  ZipCode: "XXX XXX",
  Currency: 1,
  TransactionNumber: "txn123234",
  MerchantURLs: "https://www.paytriot.co.uk/",
};

# Encrypting payment object

The encryption of the above created payment object is done with a token (Please get the token from Paytriot) as can be seen from the function shown below. The library used here is crypto-js (opens new window) and is recommended for most users.

function encryptString(customerObject, token) {
  const key = CryptoJS.enc.Utf8.parse(token);
  const iv = CryptoJS.enc.Utf8.parse(token);
  const returnEncrypted = CryptoJS.AES.encrypt(
    CryptoJS.enc.Utf8.parse(customerObject),
    key,
    {
      iv: iv,
      keySize: 128 / 8,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7,
    }
  );
  return returnEncrypted;
}

Use the above function to create the encrypted parameter and append it to the base url.

const stringParams = JSON.stringify(customerObject);

// Get the token from Paytriot
const token = "XXXXX";

// Call the function to encrypt
const encryptedParams = encryptString(stringParams, token);

// Use the BASE URL
const baseURL = "https://payment.paytriot.co.uk/MerchantPayment/Payment";

// Append all the together make the final payment URL
const paymentURL = baseURL + "?merchantpayment=" + encryptedParams;

Now redirect your customer to the paymentURL, so that they can complete the payment process.
