1. Build Integration

Steps to integrate Razorpay Payment Gateway with PHP SDK.

Follow the steps given below to integrate Razorpay Payment Gateway with your PHP website. The integration process is explained using the PHP sample app, which contains the following files:

File Name	Purpose
pay.php	Contains the Checkout parameters.
manual.php	Contains the Checkout Code.
config.php	Contains the API Keys.
verify.php	Contains the payment signature verification codes.

1.1

Download Razorpay PHP SDK

1.2

Add SDK file to your project

1.3

Create an Order in Server

1.4

Add Checkout Options

1.5

Store Fields in Server

1.6

Verify Payment Signature

1.7

Verify Payment Status

1.1 Download Razorpay PHP SDK

You can either download or run a composer command to

install 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.

1.2 Add SDK file to your Project

Unzip the SDK file and include the Razorpay.php file in your project.

1.3 Create an Order in Server

Order is an important step in the payment process.

An order should be created for every payment.
You can create an order using the
Orders API
. It is a server-side API call. Know how to
authenticate
Orders API.
The order_id received in the response should be passed to the checkout. This ties the Order with the payment and secures the request from being tampered.

Handy Tips

You can capture payments automatically with one-time

Payment Capture setting configuration

on the Razorpay Dashboard.

API Sample Code

In the sample app, the pay.php file contains the code for order creation using Orders API.

Request Parameters

Here is the list of parameters for creating an order:

amount

mandatory

integer The transaction amount, expressed in the currency subunit. 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 receipt id for this order. Maximum length is 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: Yes, the customer can make partial payments.
false (default): No, the customer cannot make partial payments.

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

Know more about

Orders API

Error Response Parameters

The error response parameters are available in the

API Reference Guide

1.4 Add Checkout Options

Add the Razorpay Checkout options to your project. For example, if you are using HTML for your front-end, create a page called pay.html and add the Pay button on your web page using the checkout code and either the:

Handler Function.
Callback URL.

Handler Function or Callback URL

Handler Function	Callback URL
When you use this: On successful payment, the customer is shown your web page. On failure, the customer is notified of the failure and asked to retry the payment.	When you use this: On successful payment, the customer is redirected to the specified URL, for example, a payment success page. On failure, the customer is asked to retry the payment.

Code to Add Pay Button

Copy-paste the parameters as options in your code:

<button id="rzp-button1">Pay</button>
<script src="https://checkout.razorpay.com/v1/checkout.js"></script>
<script>
var options = {
    "key": "YOUR_KEY_ID", // Enter the Key ID generated from the Dashboard
    "amount": "50000", // Amount is in currency subunits. Default currency is INR. Hence, 50000 refers to 50000 paise
    "currency": "INR",
    "name": "Acme Corp",
    "description": "Test Transaction",
    "image": "https://example.com/your_logo",

    "handler": function (response){
        alert(response.razorpay_payment_id);
        alert(response.razorpay_order_id);
        alert(response.razorpay_signature)
    },
    "prefill": {
        "name": "Gaurav Kumar",
        "email": "gaurav.kumar@example.com",
        "contact": "9000090000"
    },

    },
    "theme": {
        "color": "#3399cc"
    }
};
var rzp1 = new Razorpay(options);
rzp1.on('payment.failed', function (response){
        alert(response.error.code);
        alert(response.error.description);
        alert(response.error.source);
        alert(response.error.step);
        alert(response.error.reason);
        alert(response.error.metadata.order_id);
        alert(response.error.metadata.payment_id);
});
document.getElementById('rzp-button1').onclick = function(e){
    rzp1.open();
    e.preventDefault();

Handy Tips

Configure Payment Methods (Optional)

Multiple payment methods are available on Razorpay Standard Checkout.

The payment methods are fixed and cannot be changed.
You can configure the order or make certain payment methods prominent. Know more about configuring payment methods. Know more about
configuring payment methods
.

Handle Payment Success and Failure

The way the Payment Success and Failure scenarios are handled depends on the

Checkout Sample Code

you used in the last step.

Checkout with Handler Function

If you used the sample code with the handler function:

The customer sees your website page. The checkout returns the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature). Collect these and send them to your server.

Success/Failure Handling Code (Checkout with Handler Function)

"handler": function (response){
    alert(response.razorpay_payment_id);
    alert(response.razorpay_order_id);
    alert(response.razorpay_signature)}

Checkout with Callback URL

If you used the sample code with the callback URL:

Razorpay makes a POST call to the callback URL with the razorpay_payment_id, razorpay_order_id and razorpay_signature in the response object of the successful payment. Only successful authorisations are auto-submitted.

1.5 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.

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.

1.6 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:

Create a signature in your server using the following attributes:

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

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

generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);

  if (generated_signature == razorpay_signature) {
    payment is successful
  }

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.

Generate Signature on Your Server

Use the code given below to generate signature on your server:

1.7 Verify Payment Status

You can track the payment status in three ways:

Verify Status From Dashboard

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

Check if the payment id is generated and the status is captured

You can subscribe to a Webhook event that is generated when a certain event happens on 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.

Poll APIs

You can retrieve the status of the payments by polling our

Payment APIs
