How to Integrate Paytm Payment Gateway in Android App


No matter what service or product a business offers, if it involves online monetary transactions then they need payment gateway integration in Android/iOS apps. From investment apps to mobile marketplaces, modern businesses are relying on mobile payment gateway integrations for their Android and iOS apps.

It is often observed that the less complicated the payment process offered by a mobile payment gateway is, the more sales you get. The following statistics reported by Clevertap will further reinforce the need for having a robust mobile payment gateway for your app.

  • The number of consumers making mobile payments pre-COVID was about 900 million, which grew to 1.48 billion users approximately in 2020 post-pandemic.
  • 25.7% of all point-of-sale transactions were made via mobile wallet. This number is expected to reach 33% in the next three years.
  • By 2027, the mobile payment market value is anticipated to reach $12.6 trillion.

These facts are enough to tell you the future of mobile payments and mobile retail. They also tell you why it is important to develop mobile apps with payment gateways integrated into them for smooth app operations and a quick, easy, and safe checkout experience.

Android and iOS are two different platforms and mobile app development differs for both in many ways. Similarly, choosing a payment gateway for these platforms requires you to take into account certain factors which we have covered here. However, in this article, we will strictly talk about how to integrate a payment gateway in Android apps. But first things first:

What is a mobile payment gateway?

A mobile payment gateway is a technology that enables businesses to authorize and process payments in their mobile apps. It uses security protocols and encryption to pass the transaction data safely.

To put it simply and shortly, a mobile payment gateway serves as a platform that facilitates the exchange of money for a service/product between the customers and businesses.

How to choose a mobile payment gateway for your Android app

Before you get to integrate a mobile payment gateway in your Android app, ask yourself:

  • Do you want to quickly integrate a payment solution that allows customization of the payment page according to your brand? (Option #1)


  • Do you want to own the payment page and deliver a superior payment experience to your customers? (Option 2)


  • You have both, website and mobile app but get major traffic from the website. Hence, you are looking for one solution that is great for the website but at the same time optimizes the payment experience for the mobile users as well. (Option #3)

Wondering how? It’s simple. If your customer has the Paytm app installed on their smartphone, they will be able to access all the saved payment sources on their Paytm App at the time of making the payment (by invoking the Paytm App) on your mobile app.
