## Summary

**Webhook event simulator**: Added a partner-facing guide for the sandbox webhook event simulator at [simulator.sandbox.redpincompany.com](https://simulator.sandbox.redpincompany.com), which lets you exercise your webhook handler against a scripted sequence of payment lifecycle events for a given session.

## Documentation Updates

### New page

* [Test webhooks with the simulator](/api-guide/partners/webhook-simulator) — how to load a sandbox session, pick a scripted action (Successful Payment Completion, Cancel Payment), publish the event sequence, and inspect the deliveries the simulator sent to your registered callback URL.

### Cross-links

* [Webhooks overview](/api-guide/webhooks) now points to the simulator for handler verification.
* [Integration guidelines](/api-guide/partners/integration-guidelines) references the simulator within the hosted-flow webhook subscription step.
* [Getting started](/api-guide/getting-started) includes the simulator as a next step alongside webhook configuration.
