## Summary

**Breaking change in [`@redpincompany/hosted-payment-sdk` 2.0.0](https://www.npmjs.com/package/@redpincompany/hosted-payment-sdk/v/2.0.0)**: The hosted thank-you page no longer posts `VIEW_ALL_PAYMENTS`. It posts `REDPIN_PAYMENT_TRACKING_EXITED`. The SDK maps that message to `onPaymentFlowExited` (`() => void`). `onViewAllPayments` is not called.

## Documentation Updates

### Page updates

* [Quickstart setup](/api-guide/partners/quickstart-setup) — React Native SDK example and callback list now use `onPaymentFlowExited`. The callback fires when the user exits payment tracking from the thank-you page. Use it to leave the hosted flow.
