How to use razorpay api and integrate payment gateway

Razorpay is a leading payment processor in India that offers comprehensive payment solutions for businesses and individuals. To start using the Razorpay API, you need to sign up for a merchant account on their website, which will provide you with the necessary credentials and access to the API documentation. You can obtain your API credentials by going to the account settings, website and app settings, and generating the API keys. There are two main options for integrating the payment gateway on the frontend: Razorpay Hosted Integration and Custom Web Integration. For the Custom Web Integration, you need to prepare certain details such as the customer's name, email, and contact number, as well as the callback and cancel URLs. You can use the provided Python code to create an order ID and integrate the payment gateway on the frontend. After initiating a payment, Razorpay will send a callback to the specified callback URL or cancel URL, which you need to handle properly to ensure a seamless payment experience.
