What are APIs? How Businesses Utilize Web APIs

APIs contain tools that help applications communicate effectively, making software development and innovation easier. The programing program interface acts as a messenger that will translate, take requests, and give a response. Businesses have benefited greatly from using APIS to discover practical usage for previously isolated data. This article explores different types of APIs and how the business utilizes them.

Types of APIS

The APIs have different forms and designs depending on the purpose you plan to use. Some APIS can be used for the general public, while others can be used within the business. That is why a business must define the purpose they intend to use the APIS to help them choose the best one. Below are the different types of APIs.

Web APIs

Web APIs are accessible through the HTTP protocol, including those used to communicate with the browser. The web APIs differ depending on the security level and privacy. They include open, internal, external, partner, and composite APIs.

Open APIs

These APIs are present to other users and developers with a minimum restriction. They are also known as public or external APIs and may require registration and use of API keys. However, some are completely open and don’t require the API key. These are built for external purposes and can be accessed by the public. One advantage of public APIs is that it allows one to share data openly. This enables developers of any external business to integrate with the host app, making the third-party software and the API more valuable. The third parties have the advantage of leveraging the data it provides since there are no restrictions and the implementation is fast.

Internal APIs

The internal APIs differ from the open APIs in that they are only intended to be used internally by the business. They are restricted and completely hidden from the public and are meant to streamline data transfers between teams and systems. However, some companies will eventually go public with their internal APIs. The internal APIs allow sections or teams of a business to share resources and consume each program’s tools and data. Using APIs, the data transfer is regarded as efficient, traceable, and hence more secure. Internal APIs also allow efficient communication of existing and new systems with the business.

Partner APIs

The partner APIs are almost similar to the open APIS. Still, they have limited access in that only those who have a business relationship with the host company can have access. The security of partner APIs tends to be stronger as only authorized clients with official licenses are allowed. To maintain the APIs company can hire backend development company to help ensure they run smoothly. Some companies adopt this format to have greater control over who can access their resources and have a say on how their usage.

Composite APIs

The composite APIs allow developers to access different endpoints in one call or request and receive a unified response from different servers. You can also use composite APIs to make automatic responses and calls without your intervention. They help reduce the workload of APIs calls making the system faster with less complexity. Businesses offering microservices that require many internal data to make one complete task.


The above are the different types of web APIs you need to consider when looking for an APIS for your business. When choosing, it’s vital to note the terms of the host company offering the API to ensure it will align with your business specifications.
