In this blog, we will have a closer look at how we make decisions around our accounting system and how it evolved as a consequence. We will do the same for our reporting and analysis frameworks.
This is part two of a series. So, if you have not done so already, it might be nice to start with the first blog. In that one, we talked about what Adyen does at a high level, how we think about choosing between home-grown and open-source software, and how this shaped our edge services.

At Adyen, we have a very pragmatic way of approaching problems. As a result, we use simple tools to achieve great results.
The goal of this blog is to walk you through the challenges we faced in scaling our system, how we tackled those challenges, and how our system looks because of those decisions. In particular, we will pay attention to the choice between home-grown solutions versus open-source software.
In the first installment of the blog, we will discuss these topics as they relate to our edge services, and in the second part, we…
Information Technology (IT) is undoubtedly one of the most important industries today and one that is ever-growing. Every company is becoming an IT company these days. From Taxis to food delivery to banking, every industry is dominated by companies that are IT companies first and domain second. With that growth, the demand for software and tools used by other developers also grows.
As an industry it took us some time to realize the importance of user experience (UX), you will understand what I’m talking about if you have tried using the internet or any software before the 2000s, but fortunately…
At Adyen, we use Elasticsearch to power various parts of our payments platform. This includes payment search, monitoring, and log search. Let’s take a look at how we use Elastic for these different use cases and see how we capitalize on the power of Elasticsearch.
We recently did a talk about some of our Elasticsearch adventures at an Elastic meetup. You can find a recording here.
Before we look into our different use cases, it helps to get a high-level understanding of Adyen’s architecture.
At Adyen, we do many…

Everything started on the cold evening of February 3rd, Android Twitter was suddenly agitated with the news. JCenter is shutting down!
Since I can remember, JCenter has been the default repository for all Android libraries.
Ever since Android development was most commonly done on Eclipse IDE, when you create a new project, the template will have generated the whole project structure, which includes the Gradle files, and in those files a small statement that says

Adyen makes many decisions within and outside of the payment flow to provide state-of-the-art payment processing. Challenges that need to be solved include optimization of the payment conversion rates, rescuing failed subscription payments, or predicting and monitoring payment volumes, just to name a few. All of these decisions are made by enabling an array of specialized data teams to leverage the vast amount of data generated throughout the payment flow. However, to leverage this data we need a versatile platform and toolset to cater to all common needs of the data teams, while still…

When it comes to processing payments, Adyen provides a webhook to help customers (our platform’s merchants) build a complete online checkout integration.
In this blog, we’ll check out how webhooks work, and how you can implement and test webhook notifications in your checkout integration.
In short, using a webhook is a great way for your applications to receive events or notifications from a service.
To illustrate, think about your favorite local bookstore. Before you ever make a trip out to them, you’d prefer to know whether or not a certain book is in stock. …

The Payment Request API and the Payment Handler API are a set of new W3C web standard being introduced to make payments easier on a website. It is aimed at standardizing and providing a consistent user experience for payments for both end-users and for merchants.
Today we will look at what exactly the APIs are, what are its advantages and how we can use them in a web application.

The Adyen way of engineering portrays an engineer as not just a coder, but a designer, architect, tester, and operations engineer — all in one. We believe that the minimal amount of links results in the fastest time to market, therefore exposing our products to our customers more quickly.
In this article, we’ll discuss the creation of a recent application, illustrating how the many roles of an engineer brings an application from its requirements to a working solution in production.
In recent years, our team has launched and iterated on a product that…

Being the most money-involved domain of FinTech, payment processing systems like Adyen are often targeted by individuals or sophisticated organizations. Fraudsters try to generate many synthetic identities like hundreds of different email addresses or hundreds of spoofed IP addresses hoping to slip-in our payment systems, but with the help of our in-house Adyen Graph Database, we can always track them in real-time and block their fraud attempts even though they keep trying new tricks.
Adyen Graph Database is one of our in-house products that helps us to catch fraud attempts as well as identifying…
