Hello Artisan, In this post, I will tell you how to integrate the zaakpay payment gateway in the PHP application. below the zaakpay payment example code I have given all the sandbox credentials, for the production you need to get your real API keys and details from your merchant zaakpay account, I have given in this example the sandbox credentials details.

Zaakpay payment gateway service provided by "MOBIKWIK", collects payment vai credit card, debit card, UPI, net banking, and wallet balance as well as the pay later option provides. I have integrated this in a very simple way and very quick understanding.

Zaakpay is an Indian Payment Gateway, that provides a platform for merchants to accept and process online payments from customers. It offers a variety of payment options including credit cards, debit cards, net banking, UPI and other e-wallets. It also provides the merchants with a dashboard to manage and track transactions and also provides APIs to integrate it with their website or mobile application.

It enables merchants to accept payments from customers across India and also provides a secure and reliable platform for transactions. It also offers various features like recurring payments, refunds, and settlements.

It is a widely used Payment gateway in India and is trusted by many merchants and businesses.

In this zaakpay payment PHP tutorial I have given an example of payment using zaakpay, refund payment, and the status of the payment process. all the example codes I have given in the below example. also, I have included "SOURCE CODE" below with a full tutorial integration of the zaakpay in PHP.

Config.php

Create a config file to set all the zaakpay credentials in one place together for better understanding and easy to change from one file place.

<?php

$merchantIdentifier = "fb2016ffd3a64b2994a6289dc2b671a4"; //Get your merchant identifier on Zaakpay.com

$secretKey = "0678056d96914a8583fb518caf42828a" ; //Get your secret key on Zaakpay.com

//Api URL
$environment = "https://zaakstaging.zaakpay.com" ; //For Live transaction use https://api.zaakpay.com

//Payment processing URL's
$transactApi = "/api/paymentTransact/V8" ;

//Transaction update URL's
$updateApi = "/updatetransaction" ;

//Transaction check status URL's
$checkStatusApi = "/checkTxn?v=5" ;

//Url for test response file
$returnUrl = "http://localhost/Zaakpay_PHP_Integration_Kit/src/com/zaakpay/api/Response.php" ; //Change this with your response file

Checksum.php

Create a "Checksum" file that has the payment link and sends a request to the zaakpay server with the encoded format.

<?php

Class Checksum {
    static function calculateChecksum($secret_key, $all) {
        $hash = hash_hmac('sha256', $all , $secret_key);
        $checksum = $hash;
        return $checksum;
    }
    
    static function getAllParams() {
        $all = '';
        //Compatible till version 8
        $checksumsequence= array("amount","bankid","buyerAddress",
                "buyerCity","buyerCountry","buyerEmail","buyerFirstName","buyerLastName","buyerPhoneNumber","buyerPincode",

style.css

This is just a simple style, this style is not necessary for your application. this is just for the understanding purpose I have written some style CSS.

.customtable,.customtable-all{
    border-collapse:collapse;
    border-spacing:0;
    width:100%;
    display:table
}
.customtable-all{
    border:1px solid #ccc
}
.w3-bordered tr,.customtable-all tr{
    border-bottom:1px solid #ddd
}
.w3-striped tbody tr:nth-child(even){
    background-color:#f1f1f1
}
.customtable-all tr:nth-child(odd){
    background-color:#fff
}
.customtable-all tr:nth-child(even){
    background-color:#f1f1f1
}
.w3-hoverable tbody tr:hover,.w3-ul.w3-hoverable li:hover{
    background-color:#ccc
}
.w3-centered tr th,.w3-centered tr td{
    text-align:center
}
.customtable td,.customtable th,.customtable-all td,.customtable-all th{
    padding:8px 8px;
    display:table-cell;
    text-align:left;
    vertical-align:top
}
.customtable th:first-child,.customtable td:first-child,.customtable-all th:first-child,.customtable-all td:first-child{
    padding-left:16px
}
.message {
    color: limegreen;
    text-align: center;
}
.card {
    box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2);
    transition: 0.3s;
    width: 40%;
}
.card:hover {
    box-shadow: 0 8px 16px 0 rgba(0,0,0,0.2);
}
.container {
    padding: 2px 16px;
}
td {
    word-break: break-word;
}

index.php

This is the root index file for running the PHP application. I have given all three payment APIs. payment and process, refund payment, and status payment. links I gave in this index file. by clicking, we will execute API.

<?php require_once('Config.php') ; ?>
