Hi Developer community, we’ve got another exciting update to share today!
We’re announcing the new Webhook Simulation—a new capability designed to make testing and validating your webhook integrations safer, easier, and more reliable.
With this feature, you can now simulate webhook events directly from the webhook management interface, without triggering any real business processes or impacting live systems.
Here’s what you can do with it:
-
Simulation UI: Launch simulations from the existing webhook management page.
-
Event Selection: Choose from predefined event types to test.
-
Realistic Delivery: Simulated events are delivered through the same infrastructure, authentication, timeouts, and retry logic as production events.
-
Test Flagging: All test events are clearly marked with an
is_testflag so you can easily distinguish them from live events. -
Audit & Monitoring: Simulation attempts are logged with full details, just like production events.
-
Permissions Control: Only authorized users with webhook management rights can run simulations.
With the new Webhook Simulation, you can safely troubleshoot and confirm setups before going live, reduce the risk of impacting live data, and gain confidence knowing your tests mirror production delivery behavior. All test attempts are clearly flagged and logged, ensuring transparency, auditability, and compliance.
Check out the Webhook Simulation in the Deel Developer Center, or read more about it in this article.
As always, let us know how it works for you, and don’t hesitate to share questions or feedback!
