API Idempotent Design
Design safe repeat calls
Designing idempotent APIs uses stable identifiers, idempotency keys, and safe verbs to avoid duplicate effects when clients retry.
- idempotency
- keys
- put
- dedupe
- retries
Use Safe Verbs
Prefer PUT for replace and PATCH for updates with checks.
Keys
Support idempotency keys to dedupe repeated creates.
Test
Simulate retries to confirm no duplicate side effects.

Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
