“It is not the strongest of the species that survives, nor the most intelligent that will survive but the one most adaptable to change”, the above statement by Charles Darwin holds very much true during the current pandemic that the world is facing. The COVID-19 Pandemic has made the point that DIGITAL is the new way of life and it is the way forward. It has mandated every business to operate digitally overnight to survive.

Our world is now more digital than ever before, and we cannot imagine living in the 21st century without internet. As per the statista report of July 2020, 4.57 billion people were active internet users encompassing 59% of the global population. This number includes tech-savvy millennials who prefer interacting with banks and financial services via online mediums that are secure and mobile-friendly. This necessitates all banks and financial institutions to innovate themselves to offer cutting-edge technology-enabled services to meet the new tech-savvy generation's needs and get the lion's share of the market. Digital applications have not only become necessary, but they are now an integral part of today’s business era hence APIs (Application Programming Interfaces) have become more indispensable than ever before.

What is API?

API stands for Application Programming Interface. It is a set of protocols that define the interactions between multiple software intermediaries. In simple words, it is the technology under the hood, which connects one or more applications to communicate and exchange the data in real-time.

Why use APIs and what are their benefits?

APIs have been around for decades and they have the proven potential to transform businesses by offering a world of possibilities to banks and financial institutions. According to a Research and Market report, by the end of 2024, the global API management market size is expected to reach $6.2 billion from $3.02 billion in 2019. Based on the recent survey conducted by Cloud Elements, 83% of major global firms from 44 countries consider API integration a critical part of their business strategy to drive digital transformation initiatives. 77 % of the firms who participated in the survey also said that they have invested in API Management.

Below are some tangible benefits of using APIs in banking and financial Institutions:

  1. Opens new revenue streams and opportunities: Banks and financial institutions can monetize their services by sharing the data through API’s and collaborating with FinTech partners and other players. For e.g. Open banking API
  2. One platform, multiple services: By integrating the applications internally and externally, banks can offer multifold multi-dimensional services to their customers. For e.g. A net banking platform can offer investment opportunities, loans, currency transactions, payment services and so on
  3. Competitive edge with market share: Early adopters will be able to gain a competitive edge and capture the market share
  4. Business agility and streamlining of operations: Real-time integration of data from multiple systems helps banks and financial intuitions to take the right decision at right time. Real-time access to data will also help businesses to maintain costs and eliminate bottlenecks across various service levels. API management helps in automating the tasks and offers opportunities to improvise the service offerings
  5. Cater to the needs of millennials: Tech-savvy millennials understand today’s digital landscape and have high expectations around digital experience. They look for personalized products and services to meet their unique needs to be delivered quickly. For e.g. Asset and wealth management web portals/apps
  6. Meeting regulatory compliance: Regtech APIs can be a real savior for banks and financial Institutions for tasks such as regulatory reporting, transaction monitoring, compliance, identity management & control. For Ex: Payments Services Directive (PSD2) in Europe
  7. Cost effective support for business: APIs enable companies to grow their businesses faster. The beauty of the API is that it does not require firms to modernize or migrate the legacy systems or IT architecture to a new one, but services can be leveraged on the existing systems via API technology
  8. Help to focus on the core: Firms could leverage the power of APIs to free-up time that goes in mundane activities. Instead, they can invest their freed-up time and effort to focus on their core functions, for Ex. using third party authenticator services for KYC and onboarding

How do APIs work?

We understand that an API is a messenger that takes requests, translates and delivers responses between receiver and provider. Let us simplify and understand this with an example of a customer at a restaurant with a menu to order from and a waiter and kitchen. Here the waiter acts as an intermediary (API) between you and the kitchen to communicate and deliver your food choice.
