One Article to Master FinTech APIs and Knowledge Management Tools

According to Tipalti, the global financial sector's market value was projected to reach $26.5 trillion by the end of 2022. This rapid growth in the financial industry, driven by digital transformation initiatives, has fueled the widespread adoption of financial technology (FinTech). Traditional financial institutions have embraced digital transformation by providing data to third parties and charging subscription fees. Meanwhile, startups have seized opportunities to deliver new features and personalized user experiences using previously inaccessible data.

What Is a FinTech API?

A FinTech API is a specialized application programming interface (API) that allows companies to integrate banking and financial service components into their applications. The Oxford Dictionary defines FinTech as "computer programs and other technology that support or enable banking and financial services." Meanwhile, an API is a set of rules enabling software components to interact programmatically.

You may have already used FinTech APIs without realizing it. For instance, when you order food online, the app likely uses a payment processing API to verify and handle your payment. Similarly, personal finance apps often use open banking APIs to access your account balances and analyze your spending habits.

BaaS and Open Banking

FinTech is closely associated with another critical concept: Banking as a Service (BaaS). In the BaaS model, platforms provide APIs that allow FinTech companies, digital banks, or third-party providers to access the data and functionality needed to integrate financial components into applications. Third parties pay a fee for this access, a practice known as open banking.

By subscribing to BaaS platforms, FinTech companies can build new features—such as financial data aggregation across multiple accounts or innovative banking products—on top of existing financial institutions' platforms.

FinTech APIs enable financial institutions to share their data without disclosing the intricacies of their internal systems. For subscribers, third-party applications can leverage the institution's security and compliance standards.

Types of FinTech APIs

The diversity of financial services means many FinTech APIs are available. Common categories include:

1. Financial Data Providers/Aggregators:
   These APIs supply third-party applications with financial data, such as account information, transaction history, customer profiles, and account statements. Data providers usually focus on a single bank, while aggregators access data from multiple banks.

2. Payment Processors:
   Payment APIs are among the fastest-growing types of FinTech APIs. They allow apps to connect to payment platforms to verify and process transactions. Examples include Stripe, Square, PayPal, and Adyen.

3. Investment APIs:
   These include broker APIs and stock market APIs. Broker APIs let apps trade securities on behalf of users, while stock market APIs provide extensive data to support investment decisions.

4. RegTech APIs:
   Regulatory technology APIs help businesses maintain compliance by automating the collection and analysis of regulatory information and translating it into actionable compliance obligations.

5. KYC APIs:
   Know Your Customer (KYC) APIs verify user identities, monitor activities, and validate payment sources to prevent fraud and corruption.

Benefits of Using FinTech APIs

1. Reduced Costs and Faster Development:
   By accessing BaaS platform data and features via APIs, developers can avoid building financial components from scratch, saving time and reducing costs.

2. Enhanced Customer Experiences:
   Developers can focus on building core features while leveraging BaaS platforms to provide personalized user experiences.

3. Leverage Secure Infrastructure:
   FinTech APIs enable developers to rely on the existing security measures of BaaS platforms, such as authentication, fraud detection, and encryption.

4. Automated Compliance:
   RegTech APIs automate compliance processes, reducing the burden on businesses while ensuring adherence to the latest regulations.

5. Fraud Prevention:
   KYC APIs verify user identities and payment sources, safeguarding financial institutions from fraud and other illegal activities.

Spotlight on RegTech and KYC APIs

RegTech APIs:

RegTech (regulatory technology) has gained prominence, especially in the wake of the 2008 financial crisis. Its core value lies in helping businesses manage increasing regulatory demands effectively. Previously, compliance officers manually reviewed regulatory documents from multiple sources. Today, RegTech APIs simplify this process, collecting and analyzing relevant data and presenting actionable compliance obligations.

KYC APIs:

According to Swift, KYC standards are essential for mitigating risks like fraud, corruption, money laundering, and terrorism financing. KYC APIs offer advanced features, such as:

• Digital footprint analysis
• Document verification
• Anti-money laundering checks
  Some APIs, like Onfido, even incorporate biometric recognition, video verification, and electronic signatures to enhance accuracy and efficiency.
