What is a payment gateway?

A payment gateway is a tunnel that connects your bank account to the platform where you want to transfer money. It is software that allows you to execute an online transaction using several payment methods such as net banking, credit card, debit card, UPI, or one of the many online wallets available these days.

A payment gateway acts as a third party that securely transfers funds from your bank account to the merchant’s payment portal.

Let us define payment gateway in layman’s words – When you purchase a household product from a prominent digital platform such as Amazon, a payment gateway assists you in the process by transferring your money to Amazon.

How does a payment gateway Razorpay work?

Now that you have a fundamental idea of what a payment gateway is, let us find out how it works. 

A payment gateway like Razorpay focuses on securing the sensitive information provided by the user during the procedure. It provides security by encrypting data such as credit card and bank account information submitted by the user.

Step 1: A customer places an order and then clicks on the website’s Submit or Checkout button or its equivalent.

Step 2: When this occurs, the website or e-commerce platform directs the customer to a payment gateway, where he or she provides all pertinent information regarding the bank or card being used to pay. The PG then directs the user to the issuing bank or a 3D secure page, where the transaction is authorized.

Step 3: Once the payment gateway has approved the transaction, the bank checks to see if the customer has enough funds in their account to complete the transaction.

Step 4: The payment gateway notifies the merchant. If the bank responds with a “No,” the merchant sends an error message to the consumer, informing them of the problem with the card or the bank account. If the bank portal responds with a “Yes,” the merchant requests the transaction from the bank.

Step 5: The bank pays the money with the payment gateway, which then settles the money with the merchant.

When this process is finished, the consumer receives an order confirmation message.

Key Factors for Facilitating Online Tractions 

Electronic Transaction Security (SET)

The Secure Electronic Transaction (SET) is a technology solution that assures the security of online credit card transactions. SET is primarily a security protocol. To safeguard the system, it employs cutting-edge encryption techniques to ensure the secure transmission of payment information over the Internet.

This protocol is a unique technology that alerts hackers from stealing client information.

Your organization must meet certain SET requirements in order to process payments.

– Mutual authentication of both the client and the merchant

– Using data encryption to ensure the secrecy of payment and order information;

– adherence to modern security procedures

SET assists with the following tasks:

Authentication of the merchant Using a typical X.509V3 certificate, the client can validate the link between the merchant and the financial institution.

User verification. Allows the merchant to check whether the permitted credit card belongs to the legal owner or not;

Prevents payment information from being read by unauthorized people using encryption; 

Prevents tampering with the data by using fake signatures.

A Merchant Agreement 

A merchant agreement is a written agreement between the merchant and the acquiring bank that defines the parties’ rights, obligations, and assurances in the process of accepting card payments.

The rules and duties outlined in this agreement apply to each party engaging in online transactions.

How do Step up a Payment Gateway business like Razorpay?

Make a business plan

The technique for creating a business plan is to establish a thorough understanding of the company’s existing status, explain the prospects for its development, and determine what resources will be required for this.

Creating a business strategy is not an easy process for a startup. 

To properly write a business plan, you must be well-versed in the sector, grasp key financial indicators, and be able to appraise the market and its prospects. It is vital to carefully assess what services the organization will offer and how much they will charge. You must also compute the number of employees and their compensation.

Collaborate with banks

All financial institutions are required to accept Visa and MasterCard. To do so, contact the partner bank and request integration.

Establish a sales department

The sales department will be in charge of calling customers and processing transactions. To find leads, use a variety of outlets. Furthermore, your current consumers are functioning as resellers, advertising your products.

Technical assistance. If you want to grow your company, you must have a technical support department. These staff will handle client complaints, resolve disputes, debug system issues, and more.

Essential Considerations to look out for in Payment Gateway Development like Razorpay

Before diving into payment gateway software development like Razorpay, you should review some fundamental concepts to avoid falling behind. Make a plan after learning more about them.

  1. Interaction between merchants, buyers, and marketplace operators

Before you begin coding, you should describe how customers, sellers, and marketplace operators will interact with your payment gateway. Determine which products and services the parties may sell to one another. Consider who will be the buyer and seller.

A merchant of record (MoR) is the person or entity held accountable by financial authorities for initiating a user’s payment. As a fee, the selling party should move a portion of their fund to the marketplace. A marketplace, in turn, can collect all proceeds from sales and distribute portions of these funds to sellers (when serving as an MoR).

When building a transaction flow, the third party is the client of your service. Determine how much information your service will collect from clients, as well as if you will serve corporations or individuals. You might allow your users to exchange things directly. In other words, decide whether you want a B2B, B2C, or C2C marketplace. Legal aspects for AML, KYC, onboarding procedures, and so on should not be overlooked.

  1. Integration     

Select your appropriate method of integration. It is vital to integrate payment providers into your gateway. You have two options:

Redirecting the user to the Payment Provider’s designated external checkout page.

PSP integration through API, but this time with an internal checkout page. It is the obligation of your front-end team to create one.

Remember that different platforms may require one method while rejecting another. Users do not want to deal with payment card information while in a queue. PSPs can only support one of the two above-mentioned choices. So, consider whether you want an internal or external checkout page. Also, keep in mind that add-ons and side themes demand your attention as well.

Once you’ve set up a payment gateway, your sign-in and checkout processes should include a plethora of supporting processes and features. For example, risk management and anti-fraud systems. Again, you have the option of integrating a third-party source, complying with PSP risk assessments, or developing your own solution. Consider integrating SMS and email services to communicate with your clientele.

  1. Scalability         

To create a payment gateway from scratch, you must first understand the figures involved, as well as determine how quickly your system will run. Another critical step is determining how many transactions must be completed in a given time frame. The remaining factors are as follows:

Forecasted maximum peak load per minute, hour, and day.

A predicted number of transactions in a year, a few years later, and beyond.

Specific dates and times when you want to handle a specific transaction load. Consider gradually boosting capacity or having everything ready from the start.

Making accurate estimates is extremely important in this situation. Can you tell the difference between 50,000 transactions per 24 hours and 50,000 transactions in ten minutes? That’s exactly what we mean.

  1. Time to Market

The implementation time may vary depending on numerous criteria such as scalability and features. Remember this “golden rule”: The more complex the system and how smoothly it scales, the more time it will “consume” throughout the construction process. Here are a few possible scenarios:

Their product has already been completed. It may have necessary functionalities and important scalability properties. That is the way to go if consumers rush to your service, filling it with sign-up procedures and purchases. However, it is possible that you will have invested resources in infrastructure that will sit idle until your marketplace gains traction.

The product should be made available as soon as possible. This goal is impossible to achieve without the help of an expert team of software engineers. This is a high-risk variant because there is no certainty that the final product will have all the necessary scalability options. It is possible to avoid large risks by first granting access to a small number of users.

  1. System architecture 

Payment systems demand strong credibility since the consequences of not paying requested payments are severe. Credibility can be achieved when the system routes requests to an asynchronous queue.

Have you followed all of the aforementioned recommendations? The next step is to design your payment gateway. Keep in mind a few key points.

  1. Deployment       

Do you intend to deploy in a number of data centers? Do you want your payment gateway application to be available in many countries? As you do so, regulatory variables are included in the equation.

Then consider whether you want national instances to be linked to those of other nations under the umbrella of a single comprehensive system. You can make it a completely local model. Choose between a worldwide account and numerous accounts for various locations. Before making a decision on this issue, you should contact an attorney.

  1. Monitoring       

This stage is responsible for monitoring the health and condition of the infrastructure and ensuring that all system parts are operational at all times. The next step is to gain business control. It includes keeping track of the number of transactions, new sign-ups, and other activities. It is vital to ensure that the system can handle the load when the number of actions exceeds expectations.

  1. Safety

Security is something that takes your complete attention and time. Begin by being acquainted with AML and KYC regulations, as well as local laws. Make certain that you adhere to global rules, such as the well-known PCI DSS standard. When working on a custom payment gateway, ensure that each payment gateway developer follows safe coding methods.

Finally, develop a strategy for ensuring the privacy and security of personal and financial information. Consider how you will handle various safety breaches. Two-factor authentication and SSL encryption are two examples.

  1. A Dispute Resolution Interface

It is understandable that users may have some disagreements, as financial operations frequently produce many queries and concerns. Do them a favor and provide a convenient, simple interface for quickly contacting an issuing bank.

  1. API Design Expansion

Extra constraints used while setting a payment gateway provide an additional stream of cash for you and your organization. Keep in mind that creating an API entails constantly upgrading techniques and maintaining clear versioning. When people use your API, you no longer have complete control over when to modify it.

Make APIs as stable as feasible. A single API should handle a variety of payment options and information – that would be ideal.
