## User Login Id Duplicate Update

This feature is only available in the Enterprise plan. To learn more, see [our pricing page](https://fusionauth.io/pricing.md).

This event has been available since 1.30.0

This event is generated when a request to update a user with a login Id (email or username) which is already in use has been received.

Event type

user.loginId.duplicate.update

### Event Scope

This is a tenant scoped event.

Prior to version `1.37.0` this event was sent to all webhooks, and it was a webhook's responsibility to filter on the **tenantId** field.

In version `1.37.0` and later, this event will only be sent to tenants for which webhooks for this event are enabled.

### Transaction Compatibility

This event is non-transactional. The operation will succeed regardless of the webhook response status code.
