# User Registration Webhook

The **User Registration Webhook** notifies your server when a user successfully completes the registration step inside a Zotlo-hosted sales flow or checkout.

## **When This Is Triggered**

A callback is sent whenever Zotlo completes a user registration. Registration can occur in two contexts:

| Context                      | Description                                                      |
| ---------------------------- | ---------------------------------------------------------------- |
| **Self-Service Sales Sites** | Sent immediately after the user completes the registration step. |
| **Checkout**                 | Sent after a successful payment                                  |

Use this webhook to enrich CRM data, personalize onboarding, activate marketing workflows, or associate subscriptions with verified user information.
