When the details are forwarded to the payment gateway URL, the payment is debited, and the customers and the owner are both notified of the payment details.

The risk for Self Hosting payment gateways is the customer details need to be protected using a particular format. The entire onus of customer information lies in the owner’s hands; therefore, a separate technical team is required, which adds on an additional cost.

The main advantage of self-hosted gateways is it enhances user experience because the customer does not navigate away from the website during the payment process

The customers’ details regarding payment are stored in an e-commerce website accessed by API during payments.

  1. Local bank Integration/ Direct Payment Gateway

As the name suggests, the payment is processed by local banks. The customers have been directed to the bank website for the payment. The customers fill up all the details, and once the payment is made, they are redirected to an eCommerce website. The bank notifies and updates about the payment process. However, if there is any cancellation or refund, the website owner needs to inform the bank.

This type of payment service is ideal for small scale business since no complicated procedure is involved and can be easily managed by the owner.

Limitations of Payment Gateway

Payment gateways have permitted instant payment processing, access to payment channels, cross-border connectivity, and flexible integration; therefore, they have become crucial to customer experiences.

Unfortunately, many businesses are still headstrong about the traditional payment model; they reckon payment gateway as an evil monster because the service providers are tainted of being sleazy and money-grubbing, taking advantage of retailers.

To wipe off the negative connotations in the E-Commerce industry, they should focus on improving a few things:

Risk of sensitive information

Payment gateway deals with customers’ most secret and valuable information. They have customer’s data like their bank account names, credit card numbers, date of birth, etc. Deceitful and fraudulent people will be more than eager to pay a huge sum of money to access this information, and untrustworthy payment providers can sell this information to such people without customers’ knowledge.

Customers uneasiness

With fraud and treachery in the increasing technology world, customers are hesitant to pay online, involving personal information. Therefore, even if the merchant buys the payment gateway service and the customer won’t reciprocate, the merchant is at the bargain’s losing end.

Technical glitch 

Any software is bound to get corrupt when such software goes awry; it can have a delirious effect. The customers cannot make any online payments, and the technical glitch will render the merchant website inoperative. It may take a few days to troubleshoot the problem and for the website to return to normal.

Hidden fee structure

While merchant processing fee falls under to categories

  • Wholesale fees – they are the interchange rates set by issuing banks and credit card companies. They are consistent regardless of the payment gateway you choose.
  • Markups-these fees depend upon how the processor earns profits from your business. With the right selection of gateway, payments will be modest, but with the wrong gateway, you’re caught in the web of trouble. Some service providers trick you by using mystifying terms and pricing models to baffle even the most experienced business owner or retailer.

It is always advisable to find an interchange-plus pricing model that is usually transparent and cost-effective. Traditional gateways are the murkiest, charging the hidden fee. The new and updated versions model keeps pricing low but recovers cost for high volume businesses like debit transactions.

Here are few FAQS regarding Payment Gateways

How do we come to know that the information we provide is safe with a payment gateway?

The transaction is processed through an HTTPS web address. Therefore they use a signed request from the merchant to process further for a request of transaction. The signed request stays only between the merchant and the payment gateway, which means it is properly secured. After this, the IP of the requesting server is verified thoroughly to detect any fraud activity. Payment gateways backup Virtual Payer Authentication (VPA). It helps to secure the process of issuing money. Further, the 3-D secure protocol adds a much-filtered layer on top.

Is it safe to have a payment gateway?

If your business deals with an eCommerce site, there is no other way to process online payments. Within a few years, the payment platform has tremendously changed, and the new services have taken into account the customers’ safety first. This way, the merchant doesn’t get to see the credit card; instead, he sees the credit card’s information. This is called “card-not-present.” In this case, there is no way to run data on the card’s chip. This way, it is a secured process.

What are the charges or fees?

There can be different charges, i.e., monthly fees, setup fees, and registration fees. The payment processing fees or the transaction fees can be quite a surprise to you, but it is all worth it. You will have to pay the fee once all your processing with that payment gateway has started. As an online merchant, you will have to pay the fee right after you hire them.

What kind of support is available?

However, it’s easy to manage the gateway, but if you need someone to talk about the problem you are facing, you have to wait sometime as it is not available 24/7. If you cannot do the processing, then the reason must be most probably due to high-risk products. High-risk products include e-cigarettes, pornography, etc.


Payment gateways are the most integral part of customers and business merchants. Customers expect fast, seamless processes when and where it is suitable. These demands make the organization and merchant incumbent have a flexible payment gateway, easy to integrate, and able to scale with constant change in customer demands.
