An API, short for Application Programming Interface, is essentially a set of digital rules and protocols for building and interacting with software applications. It’s a way for different software applications to communicate with each other and exchange information securely and efficiently.
APIs are the technical backbone of Open Banking and any other open source financial technologies, enabling secure data sharing, user control, and the development of innovative financial services like Pulse.
When it comes to Open Banking specifically, APIs play an important role, serving as a secure bridge between third party providers (whichever financial app or service you use), and your bank. They offer a number of important security services to Open Banking users:
Data Access and Interoperability:
APIs grant authorised third party providers secure access to the financial data of your bank accounts. Thanks to this, numerous applications from different banks can be used together in a single interface, allowing you to access the financial insights in a single interface.
User Control and Consent:
Data access is safely controlled through APIs. You can choose which data you want to share, and who it gets shared with, regardless of how specific it is. It also makes it easy for access to be revoked at any time, with APIs enforcing these permissions according to your instructions.
The advanced security protocols that APIs bring such as data encryption means your financial information is always protected during transmission. For example, instead of account numbers being sent, an API will send a ‘token’ that represents your data, making them extremely secure and effective.
In the process of APIs allowing third parties to access financial data, the services are constantly improving and innovating new methods to ensure their service users banking information remains safe and secure.
