APIs and Their Working
API stands for “Application Programming Interface”. If we define this in simple words, then it is a set of protocols, routines, and tools for building software and applications. This interface mechanism allows you to use different software systems and let them communicate with each other.
Making it simple, we can say that it is just like a messenger (like WhatsApp), which lets different applications share data and functionalities.
How do APIs work?
The APIs enable communication between machines, computers, or applications by following predefined rules. As an intermediary between the two, APIs facilitate tasks and interactions by delivering data from one system to another.
According to ProgrammableWeb, there are over 25,000 APIs available for developers to use. In simple words, think of a restaurant scenario. When you place an order, the waiter acts as the API, taking your request and conveying it to the kitchen staff, who then prepare your food. Once ready, the waiter delivers the food back to your table.
Without the waiter, it would be challenging to coordinate and complete the process.
In the same way, APIs are critical in establishing communication between systems, applications, or machines. At FSSP we help our clients with building Fintech solutions from scratch and also we can guide you in having more APIs for existing fintech apps and projects.
Type of APIs
There are many types of APIs out there that you can use to make web services more efficient. But there are four common APIs: public, partner, private, and composite.
- Public APIs: These types are available to anyone using them. We can say that these are open source. API. These APIs are particularly useful for developers who wish to create new software to access data from other sources.
- Partner APIs: These are a bit more restrictive, as they are only available to distinct partners who have agreed to specific terms and conditions. This type of API is beneficial for companies that want to work together on a project, as this allows them to share data in a secure and controlled way.
- Private APIs: Private APIs are used internally within a company, and they’re not available to the public. These APIs are particularly useful for companies that want to keep their data secure and confidential.
- Composite APIs: Composite APIs are a combination of two or more APIs. This type of API is beneficial for companies that need to access data from multiple sources, as it allows them to combine different APIs into a single, easy-to-use interface.
How are APIs used in payments?
Payment APIs are revolutionizing the way merchants and eCommerce retailers accept payments. By enabling seamless communication between various entities involved in the payment process, payment APIs ensure a smooth payment experience for the business and the customer.
