import { TransactionService, ITransaction, ITransactionDetail } from 'opayo-form-integration-js';

var transactionDetail = {
"VendorTxCode": "PaymentReference-1",
"Amount": "10.00",
"Currency": "GBP",
"Description": "Test transaction",
"SuccessURL": "https://www.example.com/success",
"FailureURL": "https://www.example.com/failure",

} as ITransactionDetail;

/*
* Initiate transaction will return the object that has been transmitted to Opayo's Form Integration page in case you need it for reference.
* Calling this method will automatically submit the data to Opayo and redirect the user to Opayo's Form Integration page.
*/
var transaction = await transactionService.initiateTransaction(transactionDetail, "opayotest", "your_encryption_password") as ITransaction;
`

$3

`js
import { TransactionService, ITransactionResponse } from 'opayo-form-integration-js';

var transactionService = new TransactionService();

/*
* You will first need to grab the crypt value from the query string of the return URL from Opayo's Form Integration page.
* Passing that value into the handleTransactionResponse method will decrypt the response using your Opayo Form Integration encryption password and return it.
*/
var urlParams = new URLSearchParams(window.location.search);
var crypt = urlParams.get('crypt');
var response = await transactionService.handleTransactionResponse(crypt, "your_encryption_password") as ITransactionResponse;
