# get message by ID

`POST /instances/{id}/client/action/get-message-by-id`

## Request

- Base URL: `https://waapi.app/api/v1`
- URL: `https://waapi.app/api/v1/instances/{id}/client/action/get-message-by-id`
- Auth: HTTP bearer

Retrieve a specific message using its unique identifier. Optionally includes the media content if requested.

## Path parameters

- `id` integer, required

## Request body

- object
  - `messageId` string, required: Serialized message ID in format: <fromMe>_<chatId>_<messageHash>
  - `includeMedia` boolean: When true, includes base64 encoded media content in the response

## Response `200`

Request reached the instance. `data.status` reports whether the action was carried out; on error `data` carries `message` and `explanation`. Payload: Message details retrieved successfully.

- object
  - `status` 'success' | 'error': Whether the request reached the instance. `success` here does **not** mean the action was carried out — that is reported by `data.status`, which is the authoritative one. A malformed input arrives as `status: success` with `data.status: error`.
  - `data` union: The action's outcome. `status: success` carries the payload; `status: error` is an `actionError`.
    - object
      - `status` 'success', required: Whether the instance carried the action out — the authoritative field. In this branch it is always `success`; when the instance refused the action the whole `data` object is an `actionError` with `status: error`, `message` and `explanation`.
