## Summary

**Webhook event simulator**: Expanded the sandbox webhook event simulator to support new realistic failure and edge-case status flows: `"Cancel Payment — Funding Failure"`, `"Cancel Payment — Payout Failure"`, and `"Bounced Back"`. These updates allow developers to test end-to-end integration and error handling paths in a scripted environment.

## Documentation Updates

### Page updates

* [Test webhooks with the simulator](/api-guide/partners/webhook-simulator) — Documented the new test scenarios with step-by-step event sequence guides:
  * **Cancel Payment — Funding Failure**: Simulates a payment cancelled before the FX stage.
  * **Cancel Payment — Payout Failure**: Simulates a downstream banking rejection/failure during the payout phase.
  * **Bounced Back**: Simulates a payout rejected and returned by the recipient bank after successful debiting.
