Idempotency
Idempotency means that performing an operation multiple times has the same effect as performing it once. It is essential for retries, webhooks, and distributed systems.
The resources below cover idempotent APIs, keys, retries, and state machines. Each guide helps you design operations that are safe to repeat.
Every resource includes clear explanations, copy-paste code, and practical warnings. Use them to make informed decisions, avoid production pitfalls, and speed up your delivery. If you are just getting started, read the beginner-friendly articles first; if you are experienced, jump straight to the advanced patterns and architecture guides. New resources are added regularly, so bookmark this page and check back for the latest patterns.
