Swagger Documentation

**Introduction**

In modern software development, APIs (Application Programming Interfaces) are essential to enable communication between different services and applications. Whether you’re developing a microservice architecture or integrating third-party services, documenting your APIs is crucial. This is where **Swagger** comes in. Swagger is an open-source framework that simplifies the design, documentation, and testing of RESTful APIs.

**What is Swagger?**

Swagger is a suite of tools built around the **OpenAPI Specification** (OAS), a standard for describing RESTful APIs. Swagger allows developers to:

- **Design** APIs before writing any code.
- **Document** APIs in a user-friendly, interactive interface.
- **Test** APIs directly from the documentation.

At the heart of Swagger is the **Swagger UI**, which presents API documentation in an interactive format. Developers can read the documentation, understand the available endpoints, and even test the APIs by sending requests directly from the interface.

**Key Components of Swagger**

1. **OpenAPI Specification (OAS)**:
The OpenAPI Specification is a standard format for describing APIs. It uses YAML or JSON to outline API endpoints, request/response structures, and other necessary details.

2. **Swagger UI**:
A visual representation of your API’s documentation. Swagger…
