# How to Stop Duplicate Orders in Web Applications

## Summary

Learn how to prevent duplicate orders in web applications by implementing idempotency. Idempotency ensures that the same result is obtained regardless of how many times an API call or operation is applied. It requires an idempotency key, an idempotency layer, and persistent storage. Tools like AWS Lambda Powertools and Stripe's API documentation can be used to implement idempotency.
