API Basics - Using APIs in no-code tools
If you haven't read the previous post
you should read that first.

Have you ever wondered how apps on your phone can share information with each other, or how a website can display data from another website? The answer is APIs, or application programming interfaces.

But what exactly is an API? Simply put, an API is a set of rules and protocols that allows different software programs to communicate with each other. Think of it like a menu in a restaurant. The menu tells you what dishes are available and how to order them, but it doesn't actually prepare the food. Similarly, an API tells you what information and functionality is available in a software program, and how to access it, but it doesn't actually perform the task itself.

APIs are used everywhere in the digital world. Some common examples include:

  • Social media apps like Instagram and Twitter use APIs to share information with other apps and websites.
  • Weather apps use APIs to access real-time weather data from meteorological services.
  • E-commerce websites use APIs to integrate with payment processing services and shipping providers.
  • Your smartphone's GPS uses APIs to access location-based services.

APIs use a specific format to send and receive information. It's called HTTP (Hypertext Transfer Protocol) which is the underlying protocol of the web. API's use a specific endpoint (URL) which is designed to accept specific types of requests and return specific type of responses.

APIs are not just for developers, anyone can use them. APIs are powerful tools that allow you to access the functionality and data provided by other software systems. In the upcoming series, we will explore the basics of APIs, how to test and debug them, and how to use them with no-code tools to create customized software applications.

Stay tuned for the next post in this series where we will dive deeper into understanding API endpoints.
