Create routes for payment page initiate, initiate order, and complete order. Create web routes under routes → web.php file.

4 . Make payment page

Make payment page where user fill their details which use for creating an order. In our demo, We put Username, Email, Contact Number, Address and Amount fields in payment form. You can use fields as per your need in your website.

Create payment page under resources → views → payment-initiate.blade.php and copy the below code in your payment page.

5 . New Stylesheet file

Make a new stylesheet file for payment page look nice.

Copy below css code and paste it in public → css → style.css file.

6 . Make Payment Controller

Make a new controller with the name of PaymentController.php where we create an order and return a response to initiate the payment.

We save Razorpay Id and Key in controller.

7 . Create Checkout blade page

On this page, we provide the order details to the Razorpay function to show the transaction page. When payment is done successfully than the handler function holds the payment data and then we send this data to the controller for the payment verification process.

Create a checkout page under resources → views → payment-page.blade.php and copy the below code on your payment page.

8 . Create functions for transaction verification

After creating the checkout page. Let’s verify the transaction data which comes through the hander function in checkout page. Razorpay provide payment Id, order Id, and signature. Signature is use for verify the payment id and order id not intercepted in between this process.

Add these two functions in PaymentController.php to verify the payment.

In this tutorial, I send the user to success or failed page according to Signature verification. You can change it according to your need.
