Using the WordPress REST API

Everything you need to know to begin using the WordPress REST API

About the Book

Developers shouldn't have to search all over the web to find basic information. Yes, the edge case solutions are best found on answer sites, but the meat and potatoes information should be easy to find and easy to access. That is what this book is, it is all the information you need to get setup and use the WordPress REST API in one convenient location.

It shows you how to get started, how to bring concepts together and even includes a sample app that you can clone and play with as your own private sandbox.

Learn to use the WordPress REST API and make WordPress work harder than ever before.

About the Author

Cal Evans
Cal Evans

Many moons ago, at the tender age of 14, Cal touched his first computer. (We’re using the term “computer” loosely here, it was a TRS-80 Model 1) Since then his life has never been the same. He graduated from TRS-80s to Commodores and eventually to IBM PC’s.

For the past 17 years Cal has worked with PHP and MySQL on Linux, macOS, and Windows. He has built a variety of projects ranging in size from simple web pages to multi-million dollar web applications. When not banging his head on his monitor, attempting a blood sacrifice to get a particular piece of code working, he enjoys building and managing development teams using his widely imitated but never patented management style of “management by wandering around”.

These days, when not working with PHP, Cal can be found working on a variety of projects like Day Camp 4 Developers. He speaks at conferences around the world on topics ranging from technical talks to motivational talks for developers. If you happen to meet him at a conference, don’t be afraid to buy him a shot of Bourbon.

Cal is based in Nashville TN where he is happily married to wife 1.35, the lovely and talented Kathy. Together they have 2 wonderful kids who were both smart enough not to pursue a job in IT.

“While many WordPress developers have heard of the REST API, few know about it deeply or are apprehensive to start. Carl holds your hand and explains not only the how but the why... when you’re done with this book, you’ll want to find your own reasons to use the REST API in your projects.”

I don't think there's ever been a time in which so much was possible with PHP and WordPress. And what Cal provides in this book is a fantastic exploration of the WordPress REST API.
