Looking for Stock Market APIs?
Check out this API collection curated with the Best Stock Market APIs.
An Overview of APIs
As we increasingly rely on technology for automation and integration of our business and personal interests, API’s have become an integral part of our lives. Without knowing it, we are growing reliant on this sophisticated technology.
An Application Programming Interface (API) is a software that acts as an intermediary that gives the capability of two applications to communicate with one another.
Most of the applications you use every day rely on APIs in some capacity.
These APIs act like building blocks, allowing developers to build applications much faster. They also prevent developers from having to “reinvent the wheel,” and spend time creating functionality that already exists.
For example, when you shop online your payment is probably processed with an API like Stripe. When you get a receipt for the purchase, this is sent to your email with an API like SendGrid.
Why are APIs Important in the Financial World?
There are thousands of public APIs available, and they span categories from sports to finance.
As the need for financial services grows, firms are coming up with innovative strategies for improving their client’s web and mobile application experience.
They are implementing both private and public API’s to assist with better connectivity.
Financial institutions today utilize application and software for virtually everything.
Banks use internet banking, ATM’s and much more to facilitate payments. In such a developed financial industry, API’s have become indispensable tools that allow these firms to facilitate their connectivity while at the same time improving on service delivery.
