Payment Gateway Integeration

As the owner of a digital business, I need a reliable solution for processing payments. I am looking to integrate a payment gateway into my existing system and have decided to use Phonepe. I am confident that I can create an account with the payment gateway on my own. I don't need any extra features to the payment gateway, though of course I'm willing to explore options if I find it necessary. My aim is to have a secure payment processor set up so that my customers can checkout quickly and without any hassle.
