# Create a user account on your platform.

`POST /v1/register`

## Request

- Base URL: `https://partner.mindupload.app`
- URL: `https://partner.mindupload.app/v1/register`
- Auth: API key in header `X-Partner-Key`

## Request body

- object
  - `preferred_language` string, nullable: BCP-47-ish language code (e.g. 'en', 'zh-cn') for localized messages.
  - `username` string, nullable: The end-user's username.
  - `password` string, nullable: The end-user's password on first sign-in. After login/register, send the returned session token (JWT) here instead — the field accepts either, and reusing the token keeps raw passwords out of your storage.

  - `first_name` string, nullable
  - `last_name` string, nullable
  - `nickname` string, nullable

  - `phone_number` string, nullable
  - `avatar_id` string, nullable
  - `accept_chatroom_invitation_by_others` boolean
  - `visitor_id` string, nullable: Optional. The same device or app install identifier as for login; the first session of the new account is kept under it.

## Response `200`

Result envelope — check the success field.

- object
  - `success` boolean: Whether the call succeeded.
  - `error_message` string, nullable: Human-readable reason when success is false.
  - `error_code` string
