Requests that reuse idempotency tokens but alter request parameters now throw an errorBreaking changes
What’s new![](https://b.stripecdn.com/docs-statics-srv/assets/fcc3a1c24df6fcffface6110ca4963de.svg)
Returns an error if a request reuses an idempotency token with different parameters than the original request. Previously, errors were only returned for reusing the same idempotency token across different API endpoints.

An error is now returned for reused idempotency tokens with different parameters, preventing unintended duplicate requests.
