In simple words, a payment gateway is a business software that handles online transactions and transfers an amount between the customer and seller. This technology permits customers to integrate credit & debit cards to make payments through mobile applications. It gathers necessary information from the consumer and sends it to the banks. Funds movement into the interbank network is a complex arrangement of operations that creates risks mainly associated with security assurance. Although for the end-user, a mobile money transfer takes only a few seconds, a huge quantity of work is hidden under the hood.

Luckily, the bank is accountable for all transactions and data safety. How do you provide this information to the bank? How do you check that the user has funds on their account and belongs to the customer? What will happen if the base gets into the wrong hands? Who will be answerable for this? Mobile app developers and business owners should not bear the liability. Particularly since not everyone can get the opportunity to carry out financial operations and store user and billing info. Also, to keep such data and work directly with banks, it is essential to pass a complex licensing procedure of PCI DSS (Payment Card Industry Data Security Standard), which can take months. Integrating payment gateway in mobile apps is what will do the whole thing for you.

Payment gateway integration in an app is significant, particularly if the app deals with hotel reservations, grocery shopping, travel bookings, salon booking, etc.

As purchasing mechanisms, they allow buying content that is only found classified in your Android or iOS app. Google Play Billing and In-App Purchase take a big bite out of the merchant’s profits charging 30 percent transaction fees. So, when selling this type of in-app products or services, a merchant will only receive 70%.

Alternatively, the third-party payment gateway software has nothing to do with digital purchases but they open the door for selling physical goods and services outside an Android or iOS app. This process of integrating payment gateway in Android apps and iOS apps are made in quite a few steps and involve the use of the following components:

1. Client and server SDKs

Every payment gateway provider offers its software development kit or SDK, which can be found on the providers’ official websites and used by the developers to attach the existing app functionality and simplify work. The provider’s client and server SDKs act in concert to allow collecting and handling payment information.

2. APIs

The gateway API keys help organize SDKs and libraries as a significant part of integrating payment gateways in mobile applications. If sellers are keen to exercise more control over the checkout experience, they have to go for APIs.

3. Third-party apps

Using the third-party apps, you can easily do the payment gateway integration in Android apps and iOS apps with a gateway provider with just about no prior programming experience.

Things to consider before integrating payment gateways

Before you start executing the plan, you need to think about all the details thoroughly. We have come up with a list of subjects to take into account during your strategic planning phase so that you could witness its worthwhile effects afterward.

1. A Merchant Account

A Merchant account allows accepting payments that go through the payment gateways and payment processors settling your transactions. There are mainly two types of merchant accounts: dedicated and aggregate. The dedicated merchant account provides its owners with the corresponding Merchant ID numbers that make their businesses easier to classify, more stable, and protected from all kinds of fraud. With this, account owners get extra control over transactions and take less time to complete with the dedicated account. But these benefits will come after paying extra.

The Aggregate merchant account gives you the privilege of not paying account fees and not dealing with extended contract terms. It turns the payment gateway into an aggregator shared by several businesses, that too by the same payment gateway provider for mobile apps.

2. An Integrated Gateway

Payment gateways in mobile apps can be either hosted off-site or integrated directly into your store. Hosted gateways redirect customers to online payment service providers’ platforms where payment info is collected and processed. This method is possible if the provider is familiar with your customers and they will not be afraid when directed off your website or app. Payment gateways integrated in mobile applications, in their turn, are associated with your website or mobile app through APIs, which creates a seamless user experience but still includes more mobile app development effort. 

3. The Gateway API and Payment Request API

It progresses the method of checkout, helps purchase one API call and requires that your mobile app users complete fewer steps. Moreover, online payment service providers can offer their payment APIs, which is another great option you can get benefit from.

4. Security certificates

Payment gateways drive with sensitive data, that is credit or debit card numbers and other personal information that cannot be revealed. The term Payment Card Industry Data Security Standard (PCI-DSS) has to be no strange to those who want to implement payment gateways in mobile apps. Being compliant with this set of policies and regulations is a must for sellers handling online transactions. Some payment gateways in mobile applications can help you to make it easier to get PCI-DSS compliant but the others cannot. With or without this support, you have to avoid keeping the sensitive data outside your app server and store it in your databases after a transaction is done.

5. Ease of implementation and maintenance

And lastly, the ease of integration, which can be an important consideration from the developers’ perspective. How easy to use SDKs are, whether they are mobile platform-specific or allow implementation in a programming language of your choice, these are some of the key elements inspiring the decision to work with an individual online payment service provider.
