In the last post, we introduced the basics of APIs and how they allow different software programs to communicate with each other. In this post, we will delve deeper into the building blocks of APIs: endpoints.
An endpoint is a specific URL (Uniform Resource Locator) that is designed to accept specific types of requests and return specific types of responses. When you send a request to an API, you are sending it to a specific endpoint. The endpoint then processes the request and returns a response.
A JSON response from our example weather API might look like this:
This response contains various pieces of information about the current weather in New York City, such as the location, temperature, conditions and wind speed. Each piece of information is represented as a key-value pair. The key represents the name of the information, and the value represents the actual data. For example, the key "location" has the value "New York City".
As you can see, JSON is very easy to read and understand. It's also easy to access specific pieces of information using a programming language. This makes it an ideal format for API responses.
Endpoints can also accept different types of requests. The most common types are:
It's also common for endpoints to accept query parameters, which allow you to filter or sort the data returned by the API.
In addition to understanding endpoints, it's also important to be familiar with the response format of an API.
In the next post, we will discuss the different types of API endpoints and how to use the request body and query parameters.
A non-technical introduction to APIs, explaining what they are, how they work, and why they are important. It covers the basics of API requests and responses, and introduces the idea of using APIs to access data and functionality from other websites and applications.
