Web development is the coding or programming that enables website functionality, per the owner’s requirements. It mainly deals with the non-design aspect of building websites, which includes coding and writing markup.

Web development ranges from creating plain text pages to complex web-based applications, social network applications and electronic business applications.

The web development hierarchy is as follows:
Client-side coding
Server-side coding
Database technology

Web development refers to building, creating, and an maintaining websites. It includes aspects such as web design, web publishing, web programming, and database management.

While the terms “web developer” and “web designer” are often used synonymously, they do not mean the same thing. Technically, a web designer only designs website interfaces using HTML and CSS. A web developer may be involved in designing a website, but may also write web scripts in languages such as PHP and ASP. Additionally, a web developer may help maintain and update a database used by a dynamic website.

Web development includes many types of web content creation. Some examples include hand coding web pages in a text editor, building a website in a program like Dreamweaver, and updating a blog via a blogging website. In recent years, content management systems like WordPress, Drupal, and Joomla have also become popular means of web development. These tools make it easy for anyone to create and edit their own website using a web-based interface.

While there are several methods of creating websites, there is often a trade-off between simplicity and customization. Therefore, most large businesses do not use content management systems, but instead have a dedicated Web development team that designs and maintains the company’s website(s). Small organizations and individuals are more likely to choose a solution like WordPress that provides a basic website template and simplified editing tools.

NOTE: JavaScript programming is a type of web development that is generally not considered part of web design. However, a web designer may reference JavaScript libraries like jQuery to incorporate dynamic elements into a site’s design.

Paytm Payment Gateway Integration Using PHP

Paytm Payment Gateway Integration Using PHP

Integrate Payments with Paytm

Add Paytm Payment Gateway to your mobile app or website. Collect online payments from your customers using UPI, Debit/Credit Cards, 50+ NetBanking options and Paytm Wallet.


Just follow below steps:

Step1: First, we need to create an account at https://business.paytm.com/ and get our merchant ID and Secret Key.

Now we can start coding in our site to use the Paytm. First, we will configure the Paytm with test credentials to test our code.

Step 2. (filename – config.php)


– Use PAYTM_ENVIRONMENT as ‘PROD’ if you wanted to do transaction in production environment else ‘TEST’ for doing transaction in testing environment.
– Change the value of PAYTM_MERCHANT_KEY constant with details received from Paytm.
– Change the value of PAYTM_MERCHANT_MID constant with details received from Paytm.
– Change the value of PAYTM_MERCHANT_WEBSITE constant with details received from Paytm.
– Above details will be different for testing and production environment.

define(‘PAYTM_MERCHANT_KEY’, ‘**********’); //Change this constant’s value with Merchant key downloaded from portal
define(‘PAYTM_MERCHANT_MID’, ‘**********’); //Change this constant’s value with MID (Merchant ID) received from Paytm
define(‘PAYTM_MERCHANT_WEBSITE’, ‘**********’); //Change this constant’s value with Website name received from Paytm

/*$PAYTM_DOMAIN = “pguat.paytm.com”;
$PAYTM_DOMAIN = ‘secure.paytm.in’;

define(‘PAYTM_STATUS_QUERY_NEW_URL’, ‘https://’.$PAYTM_DOMAIN.’/oltp/HANDLER_INTERNAL/getTxnStatus’);
define(‘PAYTM_TXN_URL’, ‘https://’.$PAYTM_DOMAIN.’/oltp-web/processTransaction’);*/

define(‘PAYTM_REFUND_URL’, ”);


Step 3. Now we will create a new file(index.php) to create the payment form which will have the amount to be paid and other needed information –

header(“Pragma: no-cache”);
header(“Cache-Control: no-cache”);
header(“Expires: 0″);
<div class=”container”>
<h2>Example: Paytm Payment Gateway Integration in PHP</h2>
<form method=”post” action=”pgRedirect.php”>
<table border=”1″>
<td><input id=”ORDER_ID” tabindex=”1″ maxlength=”20″ size=”20″
name=”ORDER_ID” autocomplete=”off”
value=”<?php echo “ORDS” . rand(10000,99999999)?>”>
<td><label>CUSTID ::*</label></td>
<td><input id=”CUST_ID” tabindex=”2″ maxlength=”12″ size=”12″ name=”CUST_ID” autocomplete=”off” value=”CUST001″></td>
<td><label>INDUSTRY_TYPE_ID ::*</label></td>
<td><input id=”INDUSTRY_TYPE_ID” tabindex=”4″ maxlength=”12″ size=”12″ name=”INDUSTRY_TYPE_ID” autocomplete=”off” value=”Retail”></td>
<td><label>Channel ::*</label></td>
<td><input id=”CHANNEL_ID” tabindex=”4″ maxlength=”12″
size=”12″ name=”CHANNEL_ID” autocomplete=”off” value=”WEB”>
<td><input title=”TXN_AMOUNT” tabindex=”10″
type=”text” name=”TXN_AMOUNT”
<td><input value=”CheckOut” type=”submit” onclick=””></td>
* – Mandatory Fields

<?php include(‘footer.php’);?>


Step 4. Here in form, we have set the action=”Redirect.php”, so we will create a new file with this name –

header(“Pragma: no-cache”);
header(“Cache-Control: no-cache”);
header(“Expires: 0”);
// following files need to be included

$checkSum = “”;
$paramList = array();


// Create an array having all required parameters for creating checksum.
$paramList[“ORDER_ID”] = $ORDER_ID;
$paramList[“CUST_ID”] = $CUST_ID;
$paramList[“CHANNEL_ID”] = $CHANNEL_ID;
$paramList[“TXN_AMOUNT”] = $TXN_AMOUNT;

$paramList[“CALLBACK_URL”] = “http://phpzag.com/demo/paytm-payment-gateway-integration-in-php/pgResponse.php”;
$paramList[“MSISDN”] = 7777777777; //Mobile number of customer
$paramList[“EMAIL”] = “youremail@gmail.com”; //Email ID of customer
$paramList[“VERIFIED_BY”] = “EMAIL”; //
$paramList[“IS_USER_VERIFIED”] = “YES”; //
//Here checksum string will return by getChecksumFromArray() function.
$checkSum = getChecksumFromArray($paramList,PAYTM_MERCHANT_KEY);

<title>Merchant Check Out Page</title>
<center><h1>Please do not refresh this page…</h1></center>
<form method=”post” action=”<?php echo PAYTM_TXN_URL ?>” name=”f1″>
<table border=”1″>
foreach($paramList as $name => $value) {
echo ‘<input type=”hidden” name=”‘ . $name .'” value=”‘ . $value . ‘”>’;
<input type=”hidden” name=”CHECKSUMHASH” value=”<?php echo $checkSum ?>”>
<script type=”text/javascript”>

To handle the response of return call from paytm we need another file(Response.php) –


$paytmChecksum = "";
$paramList = array();
$isValidChecksum = "FALSE";

$paramList = $_POST;
$paytmChecksum = isset($_POST["CHECKSUMHASH"]) ? $_POST["CHECKSUMHASH"] : ""; //Sent by Paytm pg
