Routy API Overview

RESTful Standards, JSON, and HTTP Status Codes

Introduction

Welcome to the API Overview! This document provides a brief overview of the API architecture, highlighting the use of RESTful standards, JSON in request bodies and HTTP responses, as well as the correct utilization of HTTP status codes. Understanding these principles will help you effectively interact with and consume the API.

1. RESTful Standards

The API follows the principles of Representational State Transfer (REST) architecture. REST is a widely adopted architectural style for designing networked applications. It promotes a stateless, scalable, and standardized approach to building APIs.

RESTful APIs utilize the following key principles:

  • Resource-Oriented: Resources are represented as URLs (Uniform Resource Locators), allowing clients to perform operations on them using standard HTTP methods.
  • Stateless Communication: Each request from the client to the server must contain all the necessary information for the server to process it. Server-side sessions or state storage are not required.
  • Uniform Interface: APIs provide a consistent and uniform interface for interacting with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE) and status codes.

2. JSON in Request Body and HTTP Response

The API leverages JSON (JavaScript Object Notation) as the preferred data interchange format for both request payloads and responses. JSON is a lightweight, human-readable, and widely supported format for transmitting structured data.

Request Body

When making POST, PUT, or PATCH requests that require data to be sent to the server, you should include a JSON payload in the request body. The payload should conform to the expected data structure specified in the API documentation.

Example POST Request with JSON payload:

POST /api/resource
Content-Type: application/json

{
  "name": "John Doe",
  "email": "[email protected]"
}

HTTP Response

API responses are typically sent in the HTTP response body using JSON. The response body will contain the requested data or relevant information about the operation's outcome.

Example of successful response:

HTTP/1.1 200 OK
Content-Type: application/json

{
  "id": 123,
  "name": "John Doe",
  "email": "[email protected]"
}

3. Correct Usage of HTTP Status Codes

HTTP status codes convey the outcome of a client's request to the server. It is important to understand and interpret these status codes correctly to handle responses appropriately. Here are a few commonly used HTTP status codes:

  • 200 OK: The request was successful, and the response body contains the requested data.
  • 201 Created: The request to create a new resource was successful, and the response body contains the newly created resource.
  • 400 Bad Request: The request was invalid or malformed. The response body may provide more information about the error.
  • 401 Unauthorized: The client's request lacks valid authentication credentials or the provided credentials are invalid.
  • 403 Forbidden: The client is authenticated but does not have permission to access the requested resource.
  • 404 Not Found: The requested resource does not exist on the server.
  • 500 Internal Server Error: An unexpected error occurred on the server.

HTTP status codes help you determine the success or failure of your requests and guide you in handling different scenarios accordingly.

Conclusion

This API adheres to RESTful standards, utilizes JSON for request and response bodies, and employs appropriate HTTP status codes. By understanding these aspects, you'll be well-equipped to interact with the API effectively and interpret the responses correctly.
