# Webhooks Overview

> Real-time event notifications across all NowBookIt integrations.

NowBookIt supports two webhook directions:

| Direction                      | Who calls whom                                         | Auth                            |
| ------------------------------ | ------------------------------------------------------ | ------------------------------- |
| **Outbound (NowBookIt → You)** | NowBookIt posts events to your registered callback URL | None (you verify via signature) |
| **Inbound (You → NowBookIt)**  | Your system posts events to NowBookIt-hosted endpoints | HMAC signature                  |
