Fresh content for all 44 patterns is available in “A Pattern a Day”, a free online API design course from our book co-author Daniel Lübke:
“Improve your API design step by step — receive one practical API design pattern in your inbox every weekday (Mon–Fri)”
“A Pattern a Day” gives you practical API design patterns — from the foundations of API design to topics like versioning, error handling and data payload design. Each pattern mail covers its context, pattern problem, solution and consequences — short, practical and easy to digest. Each pattern mail brings a new real-world example and an illustration; tradeoffs and forces are discussed. Educational, thought provoking and fun to read!
