# Create new auth user

`POST /projects/auth/user`

> **Deprecated.**

DEPRECATED, use `/projects/{project_id}/branches/{branch_id}/auth/users` instead. Creates a new user in Neon Auth.
The user will be created in your neon_auth.users_sync table and automatically propagated to your auth project, whether Neon-managed or provider-owned.

## Request body

- NeonAuthCreateNewUserRequest
  - `project_id` string, required
  - `auth_provider` 'mock' | 'stack' | 'better_auth', required
  - `email` string, email, required
  - `name` string

## Response `201`

Creates new user

- NeonAuthCreateNewUserResponse
  - `id` string, required — ID of newly created user

## Other responses

- `default` — General Error. The request may or may not be safe to retry, depending on the HTTP method, response status code, and whether a response was received. - If no response is returned from the API, a network error or timeout likely occurred. - In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results. The following HTTP methods are considered non-idempotent: `POST`, `PATCH`, `DELETE`, and `PUT`. Retrying these methods is generally **not safe**. The following methods are considered idempotent: `GET`, `HEAD`, and `OPTIONS`. Retrying these methods is **safe** in the event of a network error or timeout. Any request that returns a `503 Service Unavailable` response is always safe to retry. Any request that returns a `423 Locked` response is safe to retry. `423 Locked` indicates that the resource is temporarily locked, for example, due to another operation in progress.
