Payment system integration may seem like a real challenge. Especially for the ones who have never done it before. But since we’re going to talk about payments and money, let’s start with some numbers!

Here are a few stats so you see how mobile commerce is booming right now:

  • More than 50% of all internet shopping traffic comes from mobile devices.
  • 4 out of 5 smartphone users (79%) have made an online purchase using their mobile devices at least once in 6 months.
  • Events as Black Friday or Cyber Monday are also not immune to mobile fever with up to 40% of sales made via smartphones.

These numbers (by OuterBox) prove that we’ve witnessed a turning point in the eCommerce sphere. No matter whether you sell goods or services your customers expect to make in-app purchases. In this article, we’ll tell you how to integrate a payment gateway in a mobile app so as to make it possible.

But let’s start our journey to the world of money transactions and credit cards with revising everything we should know about a mobile app payment gateway technology.

💸 Payment Gateway for a Mobile App: What Is It and How Does It Work?

The Payment Gateway is the technology you need to keep your mobile business running. We all know this workflow very well:

  1. A user opens an app and chooses products or services that he’d like to buy.
  2. His order goes into a shopping cart.
  3. He checks out and pays by credit/debit card.
  4. This data is transferred to the bank that issued the card to our user.
  5. The bank checks whether this person has enough money on his account and doesn’t have any limits or restrictions.
  6. If yes, the request is verified, the user is charged and you (as a merchant) will soon receive his money. If no, the request is just rejected.

Here’s how it looks:

To put a payment gateway for a mobile app into effect your development team will have to integrate a special SDK - a Software Development Kit.

For non-developers out there: the SDK is a wrapper around other services’ APIs, so developers can build their own functionality. It’s basically a special program/set of tools that lets your application interact with such services. In our case, banks play the role of those “other services”.

So when you’ll need to process a transaction, your application will use the SDK to tell the mobile payment provider “I need to charge a card with token N (a token is a unique number that is tied to each card in your app) and transaction amount $X”. And then the data will be processed without your direct interference.

You can see how everything works in this video:

To integrate a payment gateway in a mobile app, your developers have to take a few steps:

  1. Go to the website of the chosen mobile app payment gateway, to the Documentation section (we’ll share links closer to the end of this article so keep reading).
  2. Find and reuse right code samples for your application.
  3. Adjust them for your case.
  4. Great, now it should work!

However, there are a few more things that require your attention. I mean merchant accounts and PCI-DSS compliance.

Merchant Accounts

One more thing that requires our attention is merchant accounts that receive customers’ mobile app payments. The merchant account can fit into one of these two categories:

  • Dedicated merchant account
  • Aggregate merchant account

A dedicated account is the personal internet-based bank account that was set up intentionally for your business.

Pros of using a dedicated account

  1. You have full management over your account.
  2. It provides you with fast transfers - usually within 3 days.
  3. You can negotiate tailored rates for your business’s sales.

Cons of using a dedicated account

  • Harder to get approved.
  • Takes more time to get approved.
  • Set up fees are higher.

However, the most popular mobile payment gateways offer you aggregate merchant accounts. This is a collection of different accounts grouped together. So when you receive your money, it gets dropped in a pool with many other companies.

Pros of using an aggregate account

  1. They are easy to set up and supported by all the best mobile app payment gateways.
  2. It takes fewer data and efforts to set up such an account.

Cons of using an aggregate account

  • Limited management over your account.
  • Fixed fees that can’t be negotiated.
  • Money transfers may take from 2 days to a week.

PCI-DSS Compliance

Another thing you need to work with customer banking data is security standards compliance.

The certificate we’re talking about is also known as PCI-DSS - the Payment Card Industry Data Security Standard. Yet, there is some good news for you.

The PCI-DSS certification may take months (and thousands of $) but only in case you store customers’ banking data and handling mobile app payment processing on your own servers.

PCI-DSS complaince proves that you customers' data is safe and sound (*image by [Matt Anderson]({ rel="nofollow" .default-md}*)

PCI-DSS complaince proves that you customers' data is safe and sound (image by Matt Anderson)

But the payment gateways which we talk about in our article help you to avoid the headache, as they handle the PCI-DSS compliance on their end. Services like Stripe or Braintree encrypt sensitive data on their servers and send it to you as a token, so it doesn’t stay on your servers.

Since we have just mentioned some of the best mobile app payment gateways let’s take a closer look at them.

💳 Top 8 Popular Mobile Payment Gateways

In this article, we decided to focus on 8 payment gateways that in our opinion are the best options to choose from. These are:

  1. Braintree
  2. Stripe
  3. Mangopay
  5. BlueSnap
  6. PayU
  7. SecurionPay
  8. Worldpay

Let’s find the best option for your case!


Launched in 2010 (and bought by PayPal in 2013), Braintree managed to become one of the best mobile app payment gateways. It’s even enough to look at its current customers: Uber, OpenTable, StubHub, Skyscanner, and many others. Why do they prefer this service? Here are the reasons.


Gateway Details 🏦

  • It works with many payment methods

Braintree accepts payments from:

  1. Cards - Visa, Mastercard, American Express, Discover, JCB, Diners, Maestro, UnionPay
  2. Digital Wallets - PayPal, Venmo, Apple/Google/Samsung Pay, Visa Checkout, Masterpass or AMEX Express Checkout
  3. Local Payment Services - like ACH in the US, Giropay in Germany or iDEAL in the Netherlands
  • Accepts 130 currencies (including Bitcoin!).

  • Braintree introduces a new security layer that’s also known as 3D Secure 2.0. This is a frictionless authentication solution which protects users and your business against fraudulent transactions.

  • Payouts take place within 2 days.

  • Extra functionality includes recurrent billing, easy data migration, full PCI compliance, in-store payments, and wide reporting possibilities.

Pricing Details 💵

Braintree doesn’t have any hidden fees. You don’t pay for setup and any monthly fees, moreover, you don’t pay any rates for the first $50,000 processed.

Then the standard rate of 2.9% + $0.30 per transaction is applied.


  • For transactions in any non-USD currency, an extra 1% fee applies.
  • If the customer’s card was issued outside of the US, Braintree also charges an extra 1% fee.
  • For each chargeback, a flat $15 fee is assessed.

More pricing details can be found here.

Development Details ⚙️

Braintree’s documentation is great so your dev team will be probably happy to work with it.

Client SDKs are available for iOS, Android and Web (JavaScript) platforms.

Server SDKs support PHP, Python, Ruby, .NET, Node.js and Java.

The provider also offers ready-made payment UI but leaves your team an option to create a custom checkout form.

All documentation can be found here:

Stripe is a direct Braintree’s competitor and another great mobile app payment gateway. What we do like about Stripe is that it’s truly user- and developer-friendly in many ways. Let’s dive in!


Gateway Details 🏦

  • Just like Braintree, Stripe supports a lot of different payment methods. Yet, they aren’t absolutely similar (for example, Stripe doesn’t work with PayPal, so check the table below carefully)


Mastercard, Visa, American Express, JCB, Discover, Diners and UnionPay


AmEx Express Checkout, Alipay, Apple/Google/Microsoft Pay, Visa Checkout, Masterpass & WeChat Pay

🌎Local payment methods

ACH, Alipay, Bancontact, Giropay, iDEAL, EPS, P24, Sepa, SOFORT, WeChat Pay

  • The service works with 135 currencies which is a piece of good news for the customers.

  • Mobile app payment processing in Stripe is conducted on its own servers. And since you don’t have to store users’ personal data, you don’t have to worry about PCI compliance.

  • Payouts take more time than in Braintree - up to 7 days worldwide, 4 days for New Zealand but still 2 days for the US (except high-risk industries) and Australia.

  • Stripe offers advanced security functionality - a machine learning fraud system called Stripe Radar, Dynamic 3D Secure safety layer and others.

  • Broad reporting options through Web or App Dashboards. To build such reports you can use Stripe’s advanced feature called Stigma.

Pricing Details 💵

Pricing is almost no different from what Braintree offers:

  • The standard rate is 2.9% + $0.30 per transaction applies.
  • No setup or monthly fees.
  • Stripe will charge 1% more if customers pay with an international card (that isn’t listed in the table a bit earlier) or if the payment currency differs from your payout currency.
  • However, Stripe doesn’t have a fee-free option for the first $50,000 proceeded.

Development Details ⚙️

Stripe’s documentation is super clear, developer-friendly and well-structured.

Tip: your team can develop a nice & user-friendly payment form using Stripe’s custom UI toolkit.

Also, unlike Stripe and Braintree, this service provides you with more tools to customize in-app purchases processing. For example, with Mangopay you can create an adaptive workflow for your business to dispatch payments for several accounts.

Think of Uber. When the customer pays for a ride, his payment is actually split in 2: to the driver (the first account) and to the Uber itself as a commission (the second account). That’s a system Mangopay can handle.

  • Another advantage is great user protection and fraud prevention functionality.

Another interesting thing is Mangopay’s volume discounts. To put it short: the more pay-ins, the smaller the fee.

For example, if you reach 100,000 monthly pay-ins the rate drops from 1.8% to 1.6% for EUR and from 2.5% to 2.3% for USD. By reaching the next milestones you may drop it even more dramatically.

👩‍💻 Our Experience with Mangopay: Oval Money

Mangopay is another payment gateway we’ve integrated for one of our clients. We used it for developing the MVP of the Oval a couple years ago. The idea of this FinTech App was to save money, based on your spending. So, for example, set up a rule to save $3 for each cup of coffee, which you drank this week.

And here’s how we used Mangopay in it:

  1. During the Sign-Up for a new user, we created a wallet for every new user in Mangopay.
  2. Users linked their bank accounts to that wallet with the help of Yodlee API.
  3. Mangopay charged users and transferred a pre-defined amount from their account to their Oval-wallet either on a regular basis or after specific actions (e.g. $2 each time you buy a cup of coffee).

Back these days, Oval was an early stage startup. And we’re proud, that now several years later it received first €1.2M and then £1.3M funding. Inspiring, right?
