API is important to learn how this communication is provided and how to optimize it. In this section, we will examine the basic components of REST-API, including URI, HTTP Methods, and Status Codes. URI (Uniform Resource Identifier) URI is a structure that defines the address of resources and can be accessed over the internet. In the REST architecture, each resource (data or service) is represented by a unique URI. URIs allow applications to reach a specific resource by sending requests and perform operations on that resource. For example, the URI for the “ posts ” resource in a blog application might be: ` .
com/posts/ ` HTTP Methods HTTP methods are methods that determine and direct operations performed on resources. In REST-API, the following four basic methods are widely used: GET: Used to retrieve a specific resource. POST: Used to add a new resource. PUT: Used to update an existing resource. DELETE: Used to delete a specific take email marketing service resource. Thanks to these methods, applications can easily perform read, add, update and delete operations on certain resources. Status Codes Status codes are three-digit codes that indicate the results of REST-API requests and facilitate the debugging process. There are different status codes for successful and unsuccessful operations.
The most common status codes are: 200 OK: The request was successfully completed. 201 Created: A new resource was successfully created. 400 Bad Request: The request was in an incorrect format or was sent with incomplete information. 401 Unauthorized: The authentication credentials required for the request could not be provided. 404 Not Found: The requested resource could not be found. 500 Internal Server Error: An error occurred on the server side and the request could not be completed. Understanding these components is an important foundation for learning how REST-APIs work and how to use them effectively.
Application example with REST-API REST-APIs play an important role in the development of applications and services in different domains. In this section, we will work on the weather API by examining a practical REST-API application example. We will also provide information about REST-API related libraries and languages used in application development. Weather API example Weather APIs are web services that provide weather data by city and region. In this example, we will first send a request using the URI provided by a specific weather API. Then, we will process the returned JSON or XML data and present the weather reports to the users.
