Glossary: RESTGlossary

A REST API, also known as a RESTful API, is a specific type of application programming interface (API) that follows the Representational State Transfer (REST) architectural style. Here's a breakdown of the key points:

Concept:

• API: Think of it as a messenger between different software systems. It defines how programs can request and receive data from each other.
• REST: A set of guidelines for designing APIs that favor simplicity, interoperability, and scalability. Think of it as best practices for API design.

Functioning:

• REST APIs use standard HTTP methods: GET to retrieve information, POST to create new data, PUT to update data, and DELETE to remove data. This makes them familiar and easy to use for developers.
• Data is typically exchanged in JSON format, which is human-readable and widely supported.
• Each resource (like a product or user) has a unique identifier (like a URL) and is accessed through specific endpoints.

Benefits:

• Standardized: Easier for developers to understand and integrate with.
• Interoperable: Works across different platforms and programming languages.
• Scalable: Can handle large amounts of data and traffic efficiently.
• Flexible: Can be adapted to various use cases.

Examples:

• Many popular websites and services have REST APIs, like Twitter, Facebook, Google Maps, and Amazon.
• Developers can use these APIs to integrate their own applications with these services, adding new features and functionality.

Additional points:

• Not all APIs are RESTful, but REST APIs are very common due to their advantages.
• There are specific guidelines and constraints for building RESTful APIs.
• Security is important when using any API, including REST APIs.
