    "description": "Use this endpoint to add new user aliases for existing identified users, or to create new unidentified users.\n\n> __Adding a user alias for an existing user__ requires an `external_id` to be included in the new user alias object. If the `external_id` is present in the object but there is no user with that `external_id`, the alias will not be added to any users. If an `external_id` is not present, a user will still be created, but will need to be identified later. You can do this using the \"Identifying Users\" and the `users/identify` endpoint<br><br>__Creating a new alias-only user__ requires the `external_id` to be omitted from the new user alias object. Once the user is created, use the `/users/track` endpoint to associate the alias-only user with attributes, events and purchases, and the `/users/identify` endpoint to identify the user with an `external_id`.\n\n### Request Parameters\n\n| Parameter | Required | Data Type | Description |\n| --------- | ---------| --------- | ----------- |\n| `user_aliases` | Yes | Array of new user alias objects | See user alias object |\n\n### Request Components\n- [User Alias Object](https://www.braze.com/docs/api/objects_filters/user_alias_object/)<br><br>\nFor more information on `alias_name` and `alias_label`, check out our [User Aliases documentation](https://www.braze.com/docs/user_guide/data_and_analytics/user_data_collection/user_profile_lifecycle/#user-aliases)."
