How to Integrate PayUMoney in your Spree Commerce Store with RoR?

What is a Payment Gateway?

A payment gateway is a merchant service provided by an eCommerce application service provider to authenticate and process payments via various payment modes.

It plays the role of the third party that securely transfers money from your bank account via any payment mode to the merchant’s payment portal. An eCommerce web development company can assist you in integrating a payment gateway with your online store.

Various examples of payment gateways: PayUMoney, Stripe, PayPal, etc.
