What is Payment Gateway?

What is Payment GatewayA payment gateway is an application that builds a digital space for its users to have a secured transaction. The users are buyers and sellers, who agree to make an online transaction. It acts as a mediator between the customer and the payment processor.

Working with encryption that secures sensitive data, Payment gateways are now widely used for e-commerce. The payment processor here is the final decision-makers to finish a completely online payment. It helps to authenticate the customer and analyze given information.

Between buyer and seller, banks also play a vital role. The bank that serves the consumer makes sure the time and security of the transaction. In case of returns or refunds, the bank takes charge and completes the process.

Here are 4 types of widely used payment gateways to get your understanding clear.

Types of Payment GatewaysHosted Payment Gateways

These types of payment gateways direct the consumer away from the site’s checkout page. The consumer then clicks the gateway link, which redirects them to the payment service provider.

At PSP, the consumer can fill in payment details. After they have completed the payment process, they are redirected towards a website where they can checkout.

Self-hosted Payment Gateways

Consumer details are requested, and when the details are collected it is sent to the payment gateway’s URL. The data is collected within the merchant’s website.

With this type of gateway, some apps require the payment data to be provided in a specific format. Others demand a hash key or secret key.

API hosted payment gateways

Payments in this type of gateways are processed through API (Application Programming Interface) or HTTPS queries. With API-hosted payment gateways, buyers enter the credit or debit card information directly on the merchant’s checkout page.

These types of payment gateways are completely customizable and offer full control over UX and UI.

Local Bank Integration

Buyers here have to make payment on the payment gateway’s page or the bank’s website. Local bank integration payment gateway redirects the customer to the bank’s page, where they provide their payment and contact details.

It is a quick and easy step process. The consumer then is redirected back towards the merchant’s website.

How to integrate Payment Gateway into an Android App?

Stripe is one of the most convenient options for developing payment gateways into mobile applications. Here we have listed a shorter form of the process for a simpler and better understanding of the payment gateway integration into the front-end side.

Follow the steps for a clear understanding.

Install a Stripe SDK

Start with the step of adding stripe-android. For this, install the SDK and then add stripe-android to the dependencies block. The dependencies will be available on the app/build.gradle file.

Here is the code: –

App’s Configuration

First, let’s start with enabling location access for the use of Android SDK. Start with the code mentioned below to have a finely defined location access enabled on the android device.

Here is the code: –

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-2

You also have to check that the user grants permission, without their permission, the SDK won’t work. For verification, you have to override the onRequestPermission method.

Here is the code : –

Code an ephemeral key

The ephemeral key is to be added in the back-end development, but you need to create a provider class for the ephemeral key. The provider class enables the client-side to communicate with the back-end ephemeral key

Here is the Code: –

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-4

Setting up a connection Token Endpoint

In order to connect to a reader, the backend development requires giving the SDK permission of using the reader with the stripe account. Forgiving SDK this access in endpoint, the developer has to implement the ConnectionTokenProvider interface.

This function is used whenever the SDK is demanded to authenticate with readers in stripe. It also plays a role when a new connection token is needed to connect to a reader.

Here is the code: –

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-5

Initializing the SDK

The coding lifecycle for Android SDK needs a setup to prevent memory leaks and ensure proper clean-up after a long-running Terminal SDK process. The application should implement an Application Subclass using TerminalApplicationDelegate.

Here is the code:

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-6

Adding TerminalListner Object

To support the initialization, you have to provide the current application context. Using the connectionTokenProvider and the Terminallistening object, you can use it to handle events from the SDK.

Here is the code: –

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-7

This is the basic development coding lifecycle of a payment method through Stripe. Adding features like consumer sessions, payment sessions, payment methods, and many more. All these features have different types of coding systems and depend on their functioning and the level of roles to play.

How to integrate Payment Gateway into an iOS App?

Adding Stripe gateway provides a developer-friendly environment making payment options for an iPhone app. Here we have outlined the basic lifecycle of integrating Payment Gateway into the iOS app, focusing on server-side development.

Install a Stripe SDK

For developing an app that works in a completely functioning manner, you have to ensure the latest updated version of the app. There are various tools one can use for installing SDK, here we have considered Swift Package Manager.

To get started, open Xcode and follow the procedure:-

File>Swift Packages>Add Package Dependency.

Enter https://github.com/stripe/stripe-ios and choose the latest version.

Dissecting the installation process in iOS into three stages: –

  • Creating Profile
  • Punning Command
  • Updating SDK to the Latest Version

For Creating a Profile, code this line

Pod ‘Stripe’

For Running the Command, add this line

Pod install

For Updating the Command to the latest version, here’s the code

Pod update Stripe

Redirect the user to authorize the source

The sources of SDK files require redirection for the consumer to authorize payment. Also, mention a URL for the consumer to return to the app. This stage includes Implementing custom URL schemes and supporting universal links.

Here’s an example of code for it: –

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-8

Selection and Collection for Payment

Developing a payment gateway includes checking the available payment methods and selecting options required for the app development.

After selection of the payment methods, one has to determine the details for collecting it. This includes adding several elements in the backend development. For the front-end, the developers have to connect the elements and set a publishable key with StripeAPI.shared.

After setting up the environment for payment collection, you have to code for collecting a payment sheet result.

Here’s the code for it: –

How-to-Integrate-Payment-Gateway-in-your-Android-or-iOS-Application-Google-Docs-9

How to integrate Payment Gateway into a Hybrid App?

Choosing two different development platforms for two different Operating Systems costs more. There is an alternative to develop apps that work on both of the OS. This is a good choice to save money and time if you want to develop a payment gateway that works on any Operating System.

Install Ionic and Cordova plugins

Start with installing the native plugins to ensure the good functioning of the app and the payment gateway. For the installation process you use:

$ ionic Cordova plugin add com.paypal.cordova.mobilesdk

$ npm install –save @ionic-native/paypal

After installing, you can go ahead with the implementation

Implementing the Plugin

It is important to implement the plugin in your NgModule. This stage includes coding that helps in making the app more reliable for the Operating System.

Here’s an example of code for implementation
