# Fetch messages from a chatroom the user belongs to.

`POST /v1/get_chatroom_messages`

## Request

- Base URL: `https://partner.mindupload.app`
- URL: `https://partner.mindupload.app/v1/get_chatroom_messages`
- 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.
  - `page` integer, nullable
  - `page_size` integer: Maximum records requested for one server-capped page.
  - `sort_by` string, nullable
  - `sort_order` integer, nullable: Sort direction; supported values depend on the operation.
  - `use_cursor_pagination` boolean, nullable
  - `cursor_value` string, nullable: Opaque pagination cursor value from the previous page (`next_cursor_value`).
  - `cursor_id` string, nullable: Opaque pagination cursor id from the previous page (`next_cursor_id`).
  - `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.
