Mobile App Payment Gateway Integration

The goal of most of the applications is to earn money to their owners. And if you are doing mobile commerce, you are interested in the matter of efficient and safe payment gateway integrations. Fortunately, we can cover this issue for you!

How to integrate payment gateway in Android and iOS applications

First, you need to decide what type of purchases are involved. If we are talking about in-app purchases, the problem of payment processing can be solved rather simply: AppStore and Google Play services come to the aid. However, in addition to digital goods, there are physical products or subscription offers, and they should be discussed in more detail.

In this case, you will need an intermediary, namely - payment gateways.

In general, this task can be implemented in different ways, the most popular of which are the following two options:

  1. the implementation of the payment process directly within your mobile application, when you ask the user to input his card details;
  2. the user transfer to the intermediary's service which can accept payments. Then you'll get the encrypted payment information to be sure that the user's order has been fully paid.

It is very important to remember the need for a PCI-DSS compliant. PCI-DSS is a set of security rules that each application must strictly follow to be considered reliable. For example, the safest app is the second case we’ve described, when you're transferring a user to another program so that he can make his card payments. But if your app contains a payment form where the user inputs his card details, the requirements for your service are significantly increased. You must ensure that your app is immune to all sorts of hacker attacks, which means that the user data is secure.

Each intermediary has its own method of processing data and different conditions for cooperation with a client (that is you!). And it's for you to decide what kind of app payment gateway to prefer. Of course, this is an important issue, because a reliable service will help you to avoid a number of troubles associated with obtaining the PCI-DSS certificate (believe us, this process can be very time-consuming). Besides, most of them offer the opportunity to create attractive forms of payment that will aid you to design your app really nicely. This factor also matters, given that the appealing program appearance positively affects your app popularity.

We guess you are interested in how to implement payment gateway in the Android application (or in the iOS app), right?. Let's consider each case separately.

Most popular mobile app payment gateways

So, what are the most popular payment gateways for today?

#1. PayPal

Undoubtedly, PayPal payments are very popular, and the brand itself is one of the market leaders. The name “PayPal” is widely heard, even among those who have not dealt with electronic payments yet... this alone indicates the high status of the brand! And this status is deserved: PayPal is available almost all over the world and accepts payments in a variety of currencies (about 26 types!). The result is obvious: the service successfully processes 5-10 million payments every day, and this number, characterizing the multitude of PayPal clients, keeps growing. Not so bad, right?

Factors to be taken into account

By implementing payment gateway, you need to consider some important factors to ensure that the result justifies your expectations.

payment gateway integration in mobile application

#1. The payment page should be an integral part of the application

When creating the payment services page, follow your application design. Payment forms customized for other app screens are better perceived by a user.

#2. One should take into account the differences between mobile devices and desktops

A developer must understand not only psychology but also the physiology of the buyer: when a person holds a smartphone in one hand, he should be able to operate his mobile device with just a thumb. Therefore, when integrating online payment system, consider this factor. A payment page should be simplified as much as possible.

#3. Do not overload

You also need to think about how to create a mobile payment app that works really fast. Yes, app download speed matters a good deal. If the payment screen is too "heavy", the user can lose his patience and leave your program by choosing another resource.

#4. Give the buyer the necessary payment information

Do not forget to inform a user about the payment processing stage, as the process of its verification and authorization takes time.

In case of an error during the mobile app payment, explain to the shopper its reasons, whether it is an incorrectly filled payment form, lack of funds on the card, or any other problem. In addition, it is also advisable to recommend ways to solve it: you can offer the user to choose another payment method, try to pay later, contact support, etc.

#5. Security information is really important

Today almost every smartphone is a storehouse of vital data about its owner. Actually, that's why the PCI-DSS standard has been created. Indicate the information that proves that you have taken care of the security problem and protected the details of your clients’ bank cards.

All of the above items will lead to the improved user experience.
