APIs: The Backbone of our Digital World

In our daily lives, we interact with multiple APIs—often without even realizing it. But what exactly is an API and why is it crucial to the digital world?

What is an API?

‍
API stands for Application Programming Interface and acts as a connector between two programs. It allows them to communicate without needing to understand each other’s internal workings and essentially ‘talk’ to each other. By defining a precise interface, APIs enable seamless data and information exchange.

A helpful analogy is to think of APIs as waiters in a restaurant. The waiter takes your order (a request) and delivers it to the kitchen (a server). The kitchen processes your order, and the waiter sends back your ordered dish. In the computer world, the kitchen represents a server that processes data instead of food. The waiter is the API that works as a connector between the customer, that can be the end user or another program, and the server. Like a waiter the API can both deliver a request and return a response.

A Real-Life Example of an API
Take online shopping, for instance. Let’s assume that we are looking for books on an online retailer's website. Searching for a book sends a request to an API. The API interprets the request and fetches data from the retailer’s book database. After processing the request, the database sends the relevant information back to the API, which then presents the results to you.

How Do APIs Work?

Let’s take a brief look at the technical side of APIs. The process begins with a request, often involving parameters, which might resemble a URL you’d type into your browser. Instead of calling a webpage, it invokes the API.

APIs support various types of requests, each serving a specific purpose:

• GET: Retrieves data, like fetching a list of books.
• POST: Submits data, such as adding a new book to an online store’s database.
• PUT: Updates existing information.
• DELETE: Removes resources.

While GET requests are generally safe, POST, PUT, and DELETE require caution, as they modify or delete data. To prevent unauthorized access, most APIs use authentication methods ranging from simple keys or passwords to complex multi-step verification processes.

APIs at Arkwright Digital: Enhancing Digital Journeys

At Arkwright Digital, APIs are integral to the web applications we build. Almost each digital journey we build uses one or various external APIs. They enhance functionality, improve user experiences, and safeguard customer data. Here are some examples of how we use them:

1. Safeguarding Customer Data
If you’ve ever applied for a credit card, you may have encountered one of our products. Entering personal data into a web form can feel daunting, especially given the risks of data breaches. Our solution? Utilize API calls to selectively encrypt the most sensitive data at its point of origin and decrypt it only at its final destination, ensuring that less critical information remains unaffected. By ensuring that no one, not even us, has direct access to the encryption key, we make your data more secure.

2. Identity Verification Made Simple
In Germany, verifying your identity for a digital contract often involves visiting a post office. However, services for ID verification allow you to complete this process from the comfort of your home. These services operate independently of our applications, using different specifications and programming languages. Yet, thanks them providing an API, we can integrate their service into our workflows, providing seamless transitions and ensuring data is transferred securely and invisibly to the user.

3. Digital Contract Signing
Signing contracts digitally is another area where APIs shine. Whether it’s capturing a signature via a mousepad or phone or confirming with a checkbox, specialized services provide the legal framework. Through their APIs, theseservices integrate smoothly into our applications.

4. Prefilled Information for Convenience
Imagine starting an application by entering minimal information, such as your company name or scanning a QR code. APIs can then retrieve all the necessary details from a central database and prefill the information for you, saving time and enhancing the user experience. However, this often highly sensitive data must be stored securely. As a result, the feasibility of utilizing this feature varies from country to country and is most effective in nations with a high level of digitalization.

Implementing APIs: Challenges and Opportunities

While APIs are generally straightforward to use, the real challenge lies in leveraging them effectively, so that their integration benefits the product in the most optimal way. Success depends on the type of API, the provider, and the quality of documentation.

At Arkwright Digital, we continually evaluate how to implement APIs to maximize their potential. Misused APIs—whether placed in the wrong places of a user journey or underutilized—can hinder the experience and leave a bitter taste of missed potential. On the other hand, correctly implemented APIs can elevate digital products, enhancing usability and making tasks easier for users.

Our Commitment to Excellence

At Arkwright Digital, we strive to get the best out of our digital products. By refining our solutions, challenging our ideas, and identifying the best opportunities for API integration, we aim to make navigating the digital world simpler and more enjoyable for everyone.
