APIs You Won't Hate
API development is a topic very close to Phil's heart. APIs You Won't Hate started out as a book, with Phil pouring everything API related he knew, all the problems he faced, all the design decisions he wish he thought about earlier. Since the book, Phil has continued to learn and grow, thanks to new experiences, and new conversations with really smart people. Learning never stops, and the Slack channel that grew from the book subscribers and their friends has become home to the largest API chat group on the internet.

API Handyman
Hi! I’m Arnaud Lauret, the API Handyman and author of The Design of Web APIs. I like to share what I do, struggle with, learn, and teach while working in the API space. I have been working in the financial industry for 18 years and my job was always around connecting pieces of software together, hence creating and using web services or APIs. My current daily job is helping people, from executive to developers and everything in between, to understand what are APIs, why they matters and how to do them. I also help dozens of different teams to design their APIs by reviewing and challenging their designs, training them to design API and also building API design guidelines.
