According to most app developers, PayPal is the most straightforward and user-friendly payment mechanism to employ in mobile apps. On the other hand, PayPal can quickly freeze the account of either a client or a merchant if they see any evidence of suspicious activity, according to the payment method’s policy. Also, PayPal’s charge structure ($0.3 plus 3.4 percent of the purchase price) may be a little high.

What Does a Mobile Payment Gateway Mean and How Does It Work?

You can simply pay for your purchase online with your credit card by using a payment gateway. The money is processed in less than a few minutes, and your product is ready to ship.

Aside from the seller (you, as the app’s owner) and the client, there’s one more key player: the bank that processes the user’s credit card. The Mastercard or Visa credit card determines the speed and security of money transfers.

Suppose the person requests a refund due to poor product quality, damage, or other issues that do not meet the customer’s expectations. In that case, the transaction would be reversed. The acquiring bank (which belongs to the merchant) will then have to transfer the transaction directly to the issuing bank.

However, with staff working around the clock throughout the world, the services you sell will be handled faster, meeting clients’ needs worldwide regardless of time zones.

Prior to the widespread use of payment gateways in mobile applications, businesses would hire employees to handle the money transfer to the merchant’s account. Implementing payment methods that operate automatically is a wonderful and cost-effective choice these days.

Things to do Before Integrating a Mobile Payment Gateway

A list of things one should consider and examine before integrating your payment gateway into your mobile application to be appropriate, convenient for clients, and effective.

SagePay, PayPal, Skrill, Worldpay, and Payone are the most popular payment methods in Europe (Germany, Italy, France, and Spain).

UI personalization

Think about having there designed the application. Each payment gateway would have its logo, color organization, and overall style. However, not all payment connections allow you to customize the interface, so make sure to pick one that does or consider establishing a new page in your app.

Make Security Measures a Top Priority.

According to a SmallBizTrends survey, 77% of retailers have experienced some form of scam. In the case of online transactions, 29% of respondents said they had been the victim of card skimming.

You may learn about their flaws and downsides by looking up their image and reading the comments from consumers who have used this payment method to make a decision if you want to integrate them into your application.

Steps to Implement a Payment Gateway into an Android/iOS Application

In the following part, we’ll go over how to connect a payment gateway to an Android or iOS application. If you’re unaware of where to start or how long it will take to set up your payment method, this step-by-step tutorial will also help to create a payment gateway on the mobile application.

Step 1: Select PGWs and create a strategy for incorporating them.

The payment gateway that best meets your demands will be determined by the industry you work in, your organization’s size, and the country you are targeting. Consider combining two or more alternative techniques if, for example, you are running a fantastic retail app that is open to clients worldwide.

Step 2: Bringing the server-side and client-side SDKs together

Regardless of whatever payment gateway you intend to use in your app, each one will provide its own SDKs (Software Development Kits). These kits are used to gather, store, and manage all of your client’s and merchant’s payment-related information. Kits can be obtained on the payment gateway’s official site and utilized by your software engineering team to integrate into the in-app feature.

Step 3: APIs 

APIs allow developers to connect to the y and send a request for a response from a server. APIs in mobile payment gateway integrations make card payments easier and more secure, making the transactions between a seller & a customer easier and more secure.

Step 4: Safety certifications 

Payment gateways, as previously said, are advantageous because they provide a highly secure environment in which you and your user may freely communicate billing information. However, if you want to boost the level of protection, you need to consider installing extra PCI DSS-compliant certificates (Payment Card Industry Data Security Standard). SSL (Secure Sockets Layer) ensures that critical information sent between clients and merchants is kept safe.

Step 5: Processing of Payments

A one-time payment mechanism must be configured on the server when executing a transaction. You move the card information to the server after receiving it from the client. The server utilizes it to complete the payment transaction.

Best Practices for Mobile Payment Gateways Integration

Here’s a quick rundown of how to integrate a mobile payment gateway.

Merchant A/C accepts online payments and acts as a banking account for your company. Storing money from the sale in your app before transferring it to your regular bank account. Transactions are validated by your supplier and forwarded to your merchant account in the situation of a mobile payment gateway system. The merchant account can be opened with various banks and integrated with payment gateways with the bank’s support. Alternatively, credit card payment gateway firms that offer an all-in-one solution and support merchant accounts can be used (e.g., PayPal and Stripe).

Here are the two sorts of merchant accounts you should choose based on your demands and business requirements:

1. Account with a dedicated merchant

Your firm will have its own merchant a/c. While this form gives you more financial control, it’s a time-consuming and costly process that requires multiple security checks.

2. Account for all merchants together

The revenue earned by your firm is combined with money generated by other businesses in this sort of merchant account.

The Kinds of Products Do You Sell

If you want to sell the goods or services on the smartphone, you must adhere to the Google Playstore or App Store policies. For iOS developers, there are guidelines, and Google has created a specialized API for Android developers. Consider mobile payment gateway operators if you’re selling tangible goods.

Safety Certificates 

Accreditation by PCI DSS is required if you handle financial data. Because of this, PCI DSS certification takes a long time. In order to ensure compliance with PCI DSS, the first step is to make sure the database that stores credit card information is always up-to-date.


Time and effort are required to find a payment gateway solution that meets your needs and integrates payment systems. Payments in your mobile app should be enabled if you deal with any type of transaction. Implementing a mobile payment gateway will provide you with a competitive advantage. Because you’ll be able to automate online money transactions by making them last a few seconds rather than several days.
