You can create users in Neon Auth using either the Neon Console or the API. This is useful for development, testing, or manual onboarding, as it lets you quickly add users and see their profiles appear in your neon_auth.users_sync table.

  1. Creating users in the Console

    You can create users directly from the Neon Console — no app integration or API required.

    1. Go to your project's Auth page in the Neon Console.
    2. Click Create user and fill in the required details.
    3. The new user will appear in your user list and be available in your database.

  2. Creating users via the API

    You can also create users programmatically using the Neon API:

    curl --request POST \
     --url 'https://console.neon.tech/api/v2/projects/auth/user' \
     --header 'authorization: Bearer $NEON_API_KEY' \
     --header 'content-type: application/json' \
     --data '{
       "project_id": "project-id",
       "auth_provider": "stack",
       "email": "user@example.com",
       "name": "Example User"
     }'

    The new user will be created and automatically available in your neon_auth.users_sync table.
