What is API banking?
API banking, or banking APIs, are application programming interfaces specifically designed for the financial sector. These interfaces act as a bridge that allows interaction and data exchange between banking systems and other applications, both internal and external. In more technical terms, an API is a set of definitions and protocols used to develop and integrate application software.
In the banking context, APIs facilitate various operations and services, enabling third-party applications to access functions and data provided by banks safely and efficiently. This includes, for example, operations such as checking account balances and movements, making transfers and payments, and accessing information about financial products.
The concept of API banking is a response to the need for modernization in the financial sector. It allows banks to adapt to an increasingly digitalized environment, where customers demand quick and secure access to their financial services from anywhere and at any time. These interfaces enable banks to offer their services through multiple digital channels, including mobile apps, online platforms, and third-party systems, such as fintech applications.
Furthermore, API banking is fundamental for the development of a more open and collaborative banking ecosystem. They facilitate the creation of new business models and alliances between banks, fintechs, and other financial service providers, driving innovation and the expansion of services in the sector.
In summary, API banking are key technological tools that enable seamless integration and communication between banks and the digital world, enabling a wide range of services and financial operations through digital platforms.

In summary, API banking is essential for the modernization and evolution of the banking sector. They not only improve existing banking services but also create new business models in the financial field, improving the user experience and opening paths towards continuous innovation.
Types of API banking
API banking can be classified into different categories based on their functionality, scope, and the type of access they offer. Each type of API has a specific purpose and plays an important role in facilitating digital banking services. The most common types of API banking include:
Public APIs (open APIs): these APIs are available to external developers and are not restricted to internal use by the bank. They allow third parties, such as fintechs or independent developers, to create applications and services that interact with the bank. Public APIs are fundamental in driving innovation and collaboration in the financial sector, enabling the creation of new solutions and services for customers.
Private APIs (internal APIs): as the name suggests, these APIs are for internal use and are not exposed to external third parties. They are used to improve communication and the efficiency of internal bank processes. Private APIs help banks integrate different systems and departments, facilitating more efficient management and faster decision-making.
Partner APIs: these APIs are a midpoint between public and private APIs. They are shared with selected business partners under specific agreements. Partner APIs allow collaboration between banks and selected companies, such as software providers or financial services, to offer combined or enhanced services to customers.
Aggregate APIs: this type of API allows the combination of various functions or data from different sources into a single interface. They are especially useful for providing a consolidated view of a client's financial information, coming from different financial institutions. This is crucial for services such as personal finance management or account aggregation.
Payment APIs: specifically designed to facilitate financial transactions, these APIs enable the execution of payments, money transfers, and other operations related to the movement of funds. They are essential for the operation of electronic payment platforms and digital wallets.
Each of these types of API banking plays a crucial role in creating a more integrated and accessible digital banking ecosystem. Together, they contribute to the transformation of the financial sector, offering greater efficiency, security, and a better experience for the customer.
