Avoiding Déjà Vu: Building Resilient APIs with Idempotency
English session - Intermediate
Repeated API requests happen more often than we'd like - double clicks, flaky networks, retries, and proxies can all replay calls unexpectedly. Without idempotency, this can lead to duplicate charges, broken state, and confused users.
This talk explores what really goes wrong when idempotency is missing, how companies like Stripe and Shopify design for retries in practice, and why implementing idempotency is often far simpler than we expect!

This talk shares quick wins for common page speed issues, plus the metrics to prove your changes made things faster (and less painful). All without getting into the trenches with npm build processes and node version issues!
