Guides
3 guides on api design. Practical writing from the team building Atlas, useful whether or not you buy anything.
A REST API looks simple as a list of endpoints and complicated the moment you draw the calls, auth, and errors together. Diagramming it exposes the design before clients depend on it.
Sequence diagrams are where PlantUML shines, because it lays them out itself rather than deferring to Graphviz. This tutorial takes you from a two-line diagram to loops, alternatives, and activation bars.
Sequence diagrams are the sharpest tool for designing an API, because they force you to think about the full conversation - including the failures - before you build it.
