Learn how REST APIs work. This book will teach you what REST APIs are, why they are useful, and how to use them to build more scalable, faster, more efficient applications.
APIs or "Application Programming Interfaces" are computer programs that talk to other computer programs. They provide an interface for programmed applications to communicate, and they are becoming big business. REST APIs allow for faster development cycles, faster and more interactive software products, and better separation of content and presentation on any platform.
REST APIs are a standard way of providing access to data from a web server to clients such as mobile apps, web sites, or Internet of Things devices. They can allow clients to create, remove, update, or delete data, or to provide some type of data analysis. Typically, people do not interact with REST APIs directly. Instead, people interact with client software on their phone, browser, or another device, which in turn requests and modifies data from one or more REST APIs in the background.
REST API is typically programmed with a web scripting language such as Python, Ruby on Rails, or PHP, which interacts with a database or other APIs. The REST API is accessible by URL, just like a website. Except instead of requesting a website with a web browser, another software client is requesting data. The scripting language is configured to run through a web server such as Apache or NGINX so that requests can be processed and responses can be delivered back to the client via the Internet. When a client submits a request via a URL, the server determines what action to take and how to process and present any data involved. It responds with a status code, some formatting headers, and structured data.
In this book, you will learn:
- What is a REST API
- How are REST APIs used
- Why are REST APIs useful
- How REST works with HTTP
- Anatomy of a REST Request and Response
- Status messages
- Best Practices
- How to create, read, update, and delete data
- Where to find REST APIs
