A Step-by-Step Guide: Generate Dynamic QR Code with Razorpay API in PHP

Step 1: Razorpay Account:

You need to have a Razorpay account. Sign up at Razorpay if you don’t have one.

Step 2: Razorpay API Keys

To authenticate requests to the Razorpay API, you’ll need your API keys.

Log in to your Razorpay Dashboard and navigate to Settings > API Keys. Here, you’ll find your “Key ID” and “Key Secret.” Copy these credentials as you’ll need them in your PHP script to interact with the Razorpay API securely.

Create an auth.php file and Copy and Paste the following code

$razorpay_mode='test';

$razorpay_test_key='rzp_test_TlxM6W37t3zETC';
$razorpay_test_secret_key='kWxmCHmtBYxdaLRLEjsT1hQ0';
$razorpay_live_key='YOUR_KEY_ID';
$razorpay_live_secret_key='YOUR_KEY_SECRET';

if($razorpay_mode=='test'){
    
    $razorpay_key=$razorpay_test_key;
    
$authAPIkey="Basic ".base64_encode($razorpay_test_key.":".$razorpay_test_secret_key);

}else{
    
	$authAPIkey="Basic ".base64_encode($razorpay_live_key.":".$razorpay_live_secret_key);
	
	$razorpay_key=$razorpay_live_key;

}

Replace ‘YOUR_KEY_ID’ and ‘YOUR_KEY_SECRET’ with your actual Razorpay API key and secret.

Step 3: Create your HTML form to get the customer details

Create an index.php page and Copy and Paste the following code into your index.php file.

Simple Steps to Integrate Razorpay Payments to Your PHP Website

Step 4: Write the Ajax to Create Dynamic QR using Razorpay API

In this step, we’ve created the ‘submitpayment.php’ code file to manage AJAX post requests.

$billing_name,
"email"=> $billing_email,
"contact"=>$billing_mobile,
"notes" =>array(
	          "notes_key_1"=> $note,
	          "notes_key_2"=> ""
              )
);

/***** create customer on razorpay ****/
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://api.razorpay.com/v1/customers',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS =>json_encode($postdata),
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json',
    'Authorization: '.$authAPIkey
  ),
));

$response = curl_exec($curl);

curl_close($curl);
$customerRes= json_decode($response,true);


if(isset($customerRes['error'])){
 
$errMessage=$customerRes['error']['description'];

echo json_encode(['res'=>'error','message'=>$errMessage]); exit;
}else{
    
    $customerId=$customerRes['id'];
    
    /***** create razorpay qr code **********/
    $qrNote="QR code payment of ".$payAmount;
    $pdesc="Razorpay QR code Payment";
    $expiretime='';
    $qrpostData=array(
        "type"=> "upi_qr",
    "name"=> $billing_name,
    "usage"=> "single_use",
    "fixed_amount"=> true,
    "payment_amount"=> $payAmount*100,
    "description"=> $pdesc,
    "customer_id"=> $customerId,
    "notes"=> array(
        "purpose"=> $qrNote
    )
    );
    
    $curl1 = curl_init();

curl_setopt_array($curl1, array(
  CURLOPT_URL => 'https://api.razorpay.com/v1/payments/qr_codes',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS =>json_encode($qrpostData),
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json',
    'Authorization: '.$authAPIkey
  ),
));

$response1 = curl_exec($curl1);

curl_close($curl1);
$qrRes= json_decode($response1,true);
if(isset($qrRes['image_url'])){
    $qrID=$qrRes['id'];
    $qrImage=$qrRes['image_url'];
    	echo json_encode(['res'=>'success','customer_id'=>$customerId,'qr_id'=>$qrID,'qrImage'=>$qrImage]); exit;
}else{
    	echo json_encode(['res'=>'error','message'=>'Qr code not generated']); exit;
}
    
        /***** create razorpay qr code end ****/

}
}else{
    echo json_encode(['res'=>'error']); exit;
}
       ?>

In the above code,

https://api.razorpay.com/v1/customers

we are using above API to create customer on Razorpay

https://api.razorpay.com/v1/payments/qr_codes

We are using above API to create dynamic QR code. Also you can check QR Code details in Razorpay account.

Generate Dynamic QR Code with Razorpay API in PHP

Step 5: Create payNow.php file

After successfully created QR image link, we will redirect to payNow.php with parameters “qr_id”.

Create payNow.php file and copy and paste following code:





 

Qr Payment | tutorialswebsite.com
   









 



 'https://api.razorpay.com/v1/payments/qr_codes/'.$payid,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HTTPHEADER => array(
    'Authorization: '.$authAPIkey
  ),
));

$response = curl_exec($curl);

curl_close($curl);
$getQr=json_decode($response,true);

 $qrID=$getQr['id'];
    $qrImage=$getQr['image_url'];
    $imageData = base64_encode(file_get_contents($qrImage));
    $src = 'data: ;base64,' . $imageData;
    echo "";
}
    ?>

In the above code, we are using below api link to fetch qr code details using qr_id.

https://api.razorpay.com/v1/payments/qr_codes/:qr_code

When we will get QR code image url, we need to Embed image url to <img> element to display qr code as below image.

Also we are using setInterval function to check payment status every second. we are using “checkPaymentStatus.php” url as ajax to fetch payment status details.

Create checkPaymentStatus.php file and copy and paste below code

 'https://api.razorpay.com/v1/payments/qr_codes/'.$qr_id.'/payments',CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HTTPHEADER => array(
    'Authorization: '.$authAPIkey
  ),
));

$response = curl_exec($curl);

curl_close($curl);
$paymentRes= json_decode($response,true);

if(isset($paymentRes['count']) && $paymentRes['count'] !='0'){
    $items=$paymentRes['items'];
    if(is_array($items) && !empty($items)){
        $payid=$items[0]['id'];
         $payStatus=$items[0]['status'];
         if($payStatus=='captured'){
           echo json_encode(['res'=>'success','payid'=>$payid]); exit;
         }else{
              echo json_encode(['res'=>'error','message'=>"Payment not captured"]); exit;
         }
    }else{
         echo json_encode(['res'=>'error','message'=>"Payment not captured"]); exit;
    }
}

}else{
    echo json_encode(['res'=>'error']); exit;
}
       ?>

If payment captured successfully then you will redirect to payment success page.
