# About the Verification API

The Verification API allows you to implement secure member registration with a [Wix Headless](https://dev.wix.com/docs/go-headless.md) site or app by enabling email verification during authentication flows. 

A member must verify their email address in the following cases:

- The email is already associated with an existing contact. This ensures that the person attempting to register actually owns the email address and prevents unauthorized access to accounts linked to that email.
- Email verification is required by [site settings](https://manage.wix.com/my-account/site-selector/?siteType=HtmlWeb&actionUrl=https://www.wix.com/dashboard/{{metaSiteId}}/member-permissions/settings?&title=Select%20a%20site&buttonText=Adjust%20Site%20Member%20Settings).

This process ensures that only legitimate site visitors can complete registration and access member-specific features.

To learn more about the verification process, see [Handle Members with Custom Login](https://dev.wix.com/docs/go-headless/coding/rest-api/visitors-and-members/handle-members-with-custom-login.md#verify-email-address).

## Terminology

- **Member:** A site visitor who registers or logs in to your site or app and can access member-specific features.
- **Verification code:** A unique code sent to a member’s email address, used to confirm their identity during registration or authentication.
- **State token:** A token representing the current step or state in the authentication or registration process, used to track progress and ensure security.
