To make the purchase process easy for clients, most firms that offer products or services online should incorporate the best payment gateway solutions in India. This software solution allows money to be transferred from the customer's account to the seller's account in a matter of seconds.

In this blog article, we will look at how payment gateways operate and how to pick the one that is best for your company.

How Does Payment Gateway Work

A payment gateway, as a middleman between the consumer and the merchant, handles a wide variety of financial transactions, from money authorization (to verify the seller has the desired amount to pay for the purchase) to refunding in the event of a canceled sale.

Below is a scheme on how it works.

When the customer accepts the order, the payment information is transferred to the app's server and subsequently to the payment processor, card network, and issuing bank via the best payment gateway solutions in India. The bank accepts (or rejects) the transaction upon request and sends the confirmation back to the same chain of participants.

The method may appear difficult, yet the entire process takes only a few seconds.

Security Issues

As payment gateways transmit sensitive transaction information to users, they must ensure the security of data such as CVV code, card number, card holder's name, and so on. As a result, each payment gateway must maintain PCI DSS compliance, which entails robust data protection, frequent testing, encryption, and the deployment of access control components, among other things.

The Types of Payment Gateways

Depending on the size and demands of the business, there are various types of payment gateways to select from. To help you make a decision, we'll highlight their benefits and drawbacks, as well as the complexity of the integration procedure.


Customers are sent from your app to the hosted payment gateway's platform to make a payment, and they are returned after the payment is complete.

One of the primary benefits of such a solution is the ease with which payment gateways may be integrated: for apps built on popular e-commerce platforms (such as Magento or Shopify), it may be sufficient to just install an extension. If you have a bespoke online or mobile application, you may wish to engage software engineers for assistance, although most service providers provide thorough instructions on how to connect their payment gateway. Another important advantage is that the service provider also manages any security problems.

What about the drawbacks? For starters, redirecting clients to third-party services degrades the user experience and reduces conversion. Second, if you change partners, you may lose your client database because service providers store all data.

This is the best option for small and medium-sized enterprises.


Customers that use an integrated payment gateway stay on your app and the payment is processed without being redirected elsewhere.

It has a better user experience and more control over the data than a hosted gateway. Along with these benefits, there are some drawbacks: you must take care of fraud prevention and user data security (PCI DSS compliance), as well as devote more time to the best payment gateway solutions in India integration procedure. While some apps may simply connect a non-hosted payment gateway via APIs, those that operate on a proprietary engine would require technical expertise or assistance from the software development team. Integrated payment gateways will be an excellent solution for medium and big businesses.


This sort of payment gateway improves on the previous one by giving the highest level of control over payments while necessitating extensive technical knowledge. You do not need to rely on third-party services or exchange any data with them if you use your own bespoke payment gateway. Furthermore, it allows you to make any necessary alterations and changes.

Price (a software development team will be required), time (development, testing, and integration will take time), and security-related difficulties are among the downsides of this kind (meeting PCI requirements and handling documentation issues). Custom payment gateways are an alternative for large businesses and organizations.
