NodeJS SDK for Pasargad IPG

NodeJS package to connect your application to Pasargad Internet Payment Gateway through RESTful API

Installation

For installation, use npm package:

$ npm install @pepco/nodejs-rest-sdk

Usage

Redirect User to Payment Gateway

// Tip! Initialize this property in your payment service constructor method!
const PasargadApi = require('@pepco/nodejs-rest-sdk');
const pasargad = new PasargadApi(
    "YOUR_MERCHANT_CODE",
    "YOUR_TERMINAL_ID",
    "http://yoursite.com/redirect-url-here/",
    "certificate_file_location.xml"); 
    //e.q: 
    // const pasargad = new PasargadApi(xxxxxx,xxxxx,"https://pep.co.ir/ipgtest","cert.xml");

// Set Amount
pasargad.amount = 15000;

// Set Invoice Number (it MUST BE UNIQUE) 
pasargad.invoiceNumber = "4029";

// set Invoice Date with below format (Y/m/d H:i:s)
pasargad.invoiceDate = "2021/08/08 11:54:03";

// get the Generated RedirectUrl from Pasargad API (async request):
// output example: https://pep.shaparak.ir/payment.aspx?n=bPo+Z8GLB4oh5W0KVNohihxCu1qBB3kziabGvO1xqg8Y=  
pasargad.redirect().then(redirectURL => {
    // redirect user to `redirectURL`
    console.log(redirectURL);
});

Checking and Verifying Transaction

After Payment Process, User is going to be returned to your redirect_url.

payment gateway is going to answer the payment result with sending below parameters to your redirectURL (as QueryString parameters):

  • InvoiceNumber (IN field)
  • InvoiceDate (ID field)
  • TransactionReferenceID (tref field)

Store this information in a proper data storage and let's check transaction result by sending a check api request to the Bank:

// Set Transaction refrence id received in 
pasargad.transactionReferenceID = "636843820118990203";

// Set Unique Invoice Number that you want to check the result
pasargad.invoiceNumber = 4029;

// set Invoice Date of your Invoice
pasargad.invoiceDate = "2021/08/08 11:54:03";

// check Transaction result
pasargad.checkTransaction().then(response => {
    // you can handle the response here:
    console.log(response);
});

Successful result:

{
    "TraceNumber": 13,
    "ReferenceNumber": 100200300400500,
    "TransactionDate": "2021/08/08 11:58:23",
    "Action": "1003",
    "TransactionReferenceID": "636843820118990203",
    "InvoiceNumber": "4029",
    "InvoiceDate": "2021/08/08 11:54:03",
    "MerchantCode": 100123,
    "TerminalCode": 200123,
    "Amount": 15000,
    "IsSuccess": true,
    "Message": " "
}

If you got IsSuccess with true value, so everything is O.K!

Now, for your successful transaction, you should call verifyPayment() method to keep the money and Bank makes sure the checking process was done properly:

// Set Amount
pasargad.amount = 15000;

// Set Invoice Number (it MUST BE UNIQUE) 
pasargad.invoiceNumber = "4029";

// set Invoice Date with below format (Y/m/d H:i:s)
pasargad.invoiceDate = "2021/08/08 11:54:03";

// verify payment:
pasargad.verifyPayment().then(response => {
    // response
    console.log(response);
});

...and the successful response looks like this response:

{
 "IsSuccess": true,
 "Message": " ",
 "MaskedCardNumber": "5022-29**-****-2328",
 "HashedCardNumber": "2DDB1E270C598677AE328AA37C2970E3075E1DB6665C5AAFD131C59F7FAD99F23680536B07C140D24AAD8355EA9725A5493AC48E0F48E39D50B54DB906958182",
 "ShaparakRefNumber": "100200300400500"
}

Payment Refund

If for any reason, you decided to cancel an order in early hours after taking the order (maximum 2 hours later), you can refund the client payment to his/her bank card.

for this, use refundPayment() method:

// Set Unique Invoice Number that you want to check the result
pasargad.invoiceNumber = "4029";

// set Invoice Date of your Invoice
pasargad.invoiceDate = "2021/08/08 11:54:03";

// check Transaction result    
pasargad.refundPayment().then(response => {
        // handle response here:
        console.log(response);
    });
