Step 1: Download the Razorpay PHP SDK🔗

Download the latest razorpay-php.zip file from the releases section on GitHub. The razorpay-php.zip is pre-compiled to include all dependencies.

Alternatively, you can install Razorpay using a composer command.

Run the below command on your Composer:

 Install using Composer
Copycomposer require razorpay/razorpay:2.*

Step 2: Add the SDK file to your Project🔗

Follow these steps:

1. Unzip the file.
2. Include the Razorpay.php file in your application.

Step 3: Integrate Orders API🔗

Razorpay enables you to create orders and link them to payments. Order creation is an essential step as it helps you associate every payment with an order, thus preventing multiple payments.

Orders and payments go hand-in-hand. Once the payment is captured, the order is marked paid.

Orders is a mandatory step if you want to automatically capture payments. Know more about payment capture.

Create a file, for example, pay.php and add the API code given below:

 Order creation Response
Copy$orderData = [
    'receipt'         => 'rcptid_11',
    'amount'          => 39900, // 39900 rupees in paise
    'currency'        => 'INR'
];

$razorpayOrder = $api->order->create($orderData);
Copy{
  "id": "order_DBJOWzybf0sJbb",
  "entity": "order",
  "amount": 39900,
  "amount_paid": 0,
  "amount_due": 39900,
  "currency": "INR",
  "receipt": "rcptid_11",
  "status": "created",
  "attempts": 0,
  "notes": [],
  "created_at": 1566986570
}

Parameters🔗

Here is the list of parameters for creating the order:

amount mandatory

integer The transaction amount, expressed in the currency subunit, such as paise (in case of INR). For example, for an actual amount of ₹299.35, the value of this field should be 29935.

currency mandatory

string The currency in which the transaction should be made. See the list of supported currencies. Length must be of 3 characters.

receipt optional

string Pass the receipt id created for this order. Maximum length 40 characters.

notes optional

json object Key-value pair used to store additional information about the entity. Maximum 15 key-value pairs, 256 characters (maximum) each. For example, "note_key": "Beam me up Scotty”.

partial_payment optional

boolean Indicates whether the customer can make a partial payment. Possible values:

• true - The customer can make partial payments.
• false (default) - The customer cannot make partial payments.

When the order is created successfully, an order_id is returned in the response. You need to store against the order defined in your system.

Payment Capture Settings🔗

After payment is authorized, you need to capture it to settle the amount to your bank account as per the settlement schedule. Payments that are not captured are auto-refunded after a fixed time.

• Auto-capture payments (recommended)
  Authorized payments can be automatically captured. You can auto-capture all payments using global settings on the Razorpay Dashboard. Watch Out!
  Payment capture settings work only if you have integrated with Orders API in your server side. Know more about the Orders API.
• Manually capture payments
  Each authorized payment can also be captured individually. You can manually capture payments:

  • Payment Capture API

  • Razorpay Dashboard

Know more about Capture Settings for payments.

Step 4: Add Checkout Options🔗

Add the checkout options in your project. This is done in two steps:

1. Create a file, for example, manual.php in you folder and add the following code:

    Checkout code
   Copy<button id="rzp-button1">Pay with Razorpay</button>
   <script src="https://checkout.razorpay.com/v1/checkout.js"></script>
   <form name='razorpayform' action="verify.php" method="POST">
       <input type="hidden" name="razorpay_payment_id" id="razorpay_payment_id">
       <input type="hidden" name="razorpay_signature"  id="razorpay_signature" >
   </form>
   <script>
   // Checkout details as a json
   var options = <?php echo $json?>;
   
   /**
   * The entire list of checkout fields is available at
   * https://docs.razorpay.com/docs/checkout-form#checkout-fields
   */
   options.handler = function (response){
       document.getElementById('razorpay_payment_id').value = response.razorpay_payment_id;
       document.getElementById('razorpay_signature').value = response.razorpay_signature;
       document.razorpayform.submit();
   };
   
   // Boolean whether to show image inside a white frame. (default: true)
   options.theme.image_padding = false;
   
   var rzp = new Razorpay(options);
   
   document.getElementById('rzp-button1').onclick = function(e){
       rzp.open();
       e.preventDefault();
   }
   </script>
   

2. Add the checkout parameters given below in the pay.php file.

Step 5: Store Fields in Server🔗

A successful payment returns the following fields to the Checkout form.

• You need to store these fields in your server.

• You can confirm the authenticity of these details by verifying the signature in the next step.

 Success Callback
Copy{
  "razorpay_payment_id": "pay_29QQoUBi66xm2f",
  "razorpay_order_id": "order_9A33XWu170gUtm",
  "razorpay_signature": "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d"
}

razorpay_payment_id

string Unique identifier for the payment returned by Checkout only for successful payments.

razorpay_order_id

string Unique identifier for the order returned by Checkout.

razorpay_signature

string Signature returned by the Checkout. This is used to verify the payment.

Step 6: Verify Payment Signature🔗

This is a mandatory step that allows you to confirm the authenticity of the details returned to the checkout for successful payments.

To verify the razorpay_signature returned to you by the checkout:

1. Create a signature in your server using the following attributes:

   • order_id - Retrieve the order_id from your server. Do not use the razorpay_order_id returned by checkout.
   • razorpay_payment_id - Returned by checkout.
   • key_secret - Available in your server.
     The key_secret that was generated from the Razorpay Dashboard.

2. Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a HMAC hex digest as shown below:

   Copygenerated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);
   
     if (generated_signature == razorpay_signature) {
       payment is successful
     }
   

3. If the signature you generate on your server matches the razorpay_signature returned to you by the checkout, the payment received is from an authentic source.

 Verify Payment Signature
Copyrequire('razorpay-php/Razorpay.php');
use Razorpay\Api\Api;
use Razorpay\Api\Errors\SignatureVerificationError;

$success = true;

$error = "Payment Failed";

if (empty($_POST['razorpay_payment_id']) === false)
{
    $api = new Api($keyId, $keySecret);

    try
    {
        // Please note that the razorpay order ID must
        // come from a trusted source (session here, but
        // could be database or something else)
        $attributes = array(
            'razorpay_order_id' => $_SESSION['razorpay_order_id'],
            'razorpay_payment_id' => $_POST['razorpay_payment_id'],
            'razorpay_signature' => $_POST['razorpay_signature']
        );

        $api->utility->verifyPaymentSignature($attributes);
    }
    catch(SignatureVerificationError $e)
    {
        $success = false;
        $error = 'Razorpay Error : ' . $e->getMessage();
    }
}

if ($success === true)
{
    $html = "<p>Your payment was successful</p>
             <p>Payment ID: {$_POST['razorpay_payment_id']}</p>";
}
else
{
    $html = "<p>Your payment failed</p>
             <p>{$error}</p>";
}

echo $html;

Test Payments🔗

You can make test payments using any of the payment methods available at the checkout. No money is deducted from the customer's account as this is a simulated transaction. In the checkout code, ensure that you have entered the API keys generated in the test mode.

Test Cards🔗

You can use any of the test cards to make transactions in the test mode. Use any valid expiration date in the future and any random CVV to create a successful payment.

From the Dashboard🔗

1. Log into the Razorpay Dashboard and navigate to Transactions → Payments.
2. Check if a payment_ID has been generated. If no payment_ID has been generated, it means that the transaction has failed.

Subscribe to Webhook events🔗

You can subscribe to a Webhook event that is generated when a certain event happens in our server. When one of those events is triggered, Razorpay sends the Webhook payload to the configured URL.

Know how to set up Webhooks.

Given below is the webhook signature verification sample code.

PHP
Copy// PHP SDK: https://github.com/razorpay/razorpay-php
use Razorpay\Api\Api;
$api = new Api("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

$api->utility->verifyWebhookSignature($webhookBody, $webhookSignature, $webhookSecret);
// $webhookBody should be raw webhook request body

Poll APIs🔗

You can retrieve the status of the payments by polling our Payment APIs.
