We live in a fast-paced world ruled by smart and effective technologies. We encounter technologies every day that are not just amazing, but also useful. For instance, there was a time when adding a new feature to a website seemed impossible, but today, you can find thousands of free APIs on an API marketplace.
APIs are a great way to add prompt functionalities and features to your websites or mobile apps. They connect you with third-party applications so that you can fetch their data and sources with just a tap. Software companies no longer have to scratch their heads for months hoping to find a solution to add dynamic features to a website.
But Wait, What is an API?
API is an acronym for Applications Programming Interface. It’s a software intermediary that enables websites and mobile applications to communicate with an external source/service to get the desired result. To put things into perspective, you’re using APIs every time you’re using a web browser.
Let’s say you’re using a web browser, and you type www. Youtube.com, it will send a request to Youtube’s remote browser. The moment your browser receives a response, it will interpret the code and display the desired webpage.
If you’re a newbie in software development or a startup owner wondering how you could make your website more convenient and user-friendly, the good news is, that there are thousands of free APIs available on different API marketplaces. Only RapidAPI and ProgrammableWeb offer more than 70,000 APIs. However, developers believe that only 1% of all the available APIs are useful.
Never confuse APIs with Webhooks
