REST APIs are frequently used in today’s technologies and software systems. While many enterprises produce REST APIs and provide data to external systems, many enterprises obtain their data needs from external systems through REST APIs. Since the use and popularity of APIs have increased recently, it is possible to find APIs in almost every category and perform API integrations. So what exactly does it mean to perform a single API integration?

Almost every software project implements API integrations. However, it should not be forgotten that performing API integration is a serious process from start to finish and creates serious costs in cases where wrong steps are taken. In this article, we will explain exactly what API integration is. Then we will touch on multiple topics such as API integration methods and use cases.

What Is API Integration?

API integration is when one software application connects to use another application’s API to extend its perspective and functionality. That is, seamlessly adding a different API to the target application in a compatible way. API integrations power processes at virtually every layer and department of a business to keep data in sync, increase productivity, and more.

Find APIs for multiple categories that you can easily integrate into your apps.

What Should Be Considered in the API Integration Process?

API integrations provide many convenience and speed to businesses. However, an API integration that is not done correctly will do more harm than good to businesses. There are some points to consider when performing an API integration. Some of these points are as follows.

API documentation: The first thing to do in the API integration process is to read and understand the API documentation. For instance, by reading the API documentation, developers learn about API examples, error messages, response formats, and more. Otherwise, an integration without learning this information will not yield successful results.

Secure connection: The security factor always takes priority in the API integration process. It is important to establish a secure connection in the processes of receiving and providing data from external systems. Additionally, authentication, data encryption, and taking other security measures provide a correct API integration for businesses.

Performance control: API integration is the connection of the application with external systems. The performance of this connection directly affects the performance of the application as well. During the API integration process, it is essential to perform performance tests on the integrated API within the application and analyze its performance.

Top Use Cases of API Integrations

In this section, we will talk about the most used use cases of API integrations.

Web Scraping

Web scraping APIs are among the most popular APIs integrated into projects today. These APIs provide a seamless stream of data from target websites to the applications they are used in. In this way, applications can automatically obtain the data they need with these APIs.
