How to Test a Payment Gateway

Payment Gateway

Online payment gateways are great for businesses of all sizes. To get the most out of the system, you have to find out what works best for the company. That is why testing a payment gateway is easy and will help decide which features to prioritize.

Prepare A List

Before testing a payment gateway, make sure that you have all of the relevant data. This is especially important for a payment gateway in India where a lot of positive consumer traffic is created. Having the right data on hand keeps things moving at a brisk pace while helping testers stay on task. The first thing a company should secure is payment gateway documentation provided by the service provider. For most providers, this information is available before you sign a contract.

If the actual documentation is more on the ‘salesy’ side, then insist on information that veers into the technical territory – there is a major difference between the two. At the very least, you should have access to a processor sandbox. This allows you a safe testing environment to try out the major features of a payment gateway. Even if the documentation is sparse, this particular feature will get you through most testing hurdles.

Prepare The Workers

Once you start testing, don’t dump the duties on regular workers. Testing a payment gateway is not a side activity for any average employee. For smaller operations, using current employees is a tempting way to save money. The downside to this method is that even with great documentation, there are a lot of test cases that will be missed by the worker.

Once you go live with a payment gateway, the lack of testing will be on full display. Instead of your employees being the testers, potential consumers will unwillingly opt-in. When something goes wrong, money is lost on both sides.

Take the testing phase seriously by offloading the work to an experienced team. If you can’t spare the resources, then reach out to the service provider. There may be arrangements available to train your staff on proper testing and using the payment gateway.

Testing Methods

Having a virtual environment helps with testing, but you still need to understand the limits of the platform. Every payment processor is different, so testing methods will differ based on the product requirements. Beyond the normal functional testing, you’ll have to go through everything as a normal customer would.

Integration testing is a requirement for online websites that want to combine their platform with a payment gateway. In this scenario, the integration makes sure that the bridge between the two services is solid. Testing starts by making a purchase and then verifying that the money has been sent to the appropriate account. The last part of the test has to do with voiding or refunding purchases.

Performance testing checks how much of a load the payment service can handle. There should be no noticeable slowdown, even if you have multiple people trying to access the gateway. During the test, you overwhelm the service to find out its limitations. A payment gateway should be able to handle the same amount of traffic as your website. If it fails well below the limit, then you’ll miss out on important transactions.

Why Do You Need to Test a Payment Gateway?

If this question is on your mind, then testing becomes twice as important. Before jumping into the security portion of the testing, take some time to look over the way your entire operation works. This is an optional but highly recommended part of the testing process.

A payment gateway is an ecommerce service that handles online purchases. It ties together business and consumer’s resources to meet in one central place. An application with data of this magnitude requires a platform that is capable of handling large amounts of data exchanges. Testing is not a soft requirement – it is mandatory.

Think of how bad day one rollouts of any application or service would fair in an environment without pretesting. Once you’re done testing a payment gateway, the terminology and positives will make more sense. There is also a chance it will force you to evaluate current or future service implementations. It is time-consuming, but good business for all involved.


Before calling the testing phase a success, go over any issues that affect security. Your current web hosting service may have compatibility issues with a chosen payment gateway. Look for small incompatibilities and address them immediately. Be prepared for slowdowns when testing for security issues in a payment gateway. Although it’s a small inconvenience, the time used will prevent serious issues when the gateway goes live.

Top payment gateways come with several layers of security out of the box. But even the best provider isn’t equipped to handle bad hardware or software decisions on your side. When possible, prioritize security on your end to meet the same wall provided by a payment gateway.

Convenience Matters

Payment gateways are an important piece to creating a cashless economy. Companies that want to capitalize on these features should be ready to do their own testing. With all of the payment choices available, ease of use should always be at the top of the list.

A cashless economy is a convenience for both the consumer and business. With fewer resources used to handle cash, a business will likely maximize its online profits. Consumers get the benefit of modern e-commerce without the worry of a company that has stretched its resources too thin.

Banks that have invested in top-tier apps can finally utilize better technology. A few years ago, banks were hesitant to include access to payment gateways in their software. The technology has since improved tenfold, which has led to a drastic improvement in how bank apps handle online transactions.

Payment gateways have single-handedly changed the way consumers, companies and banks interact with one another.

Summing Up: Payment Gateways Are Here to Stay

Payment gateway testing will evaluate your current setup. It finds any issues associated with online purchases and transactions from potential users. To keep dependability high, test your payment gateway on a regular basis.
