# Upload Attachment

`POST /api/me/conversations/{conversation_id}/attachments`

## Request

- Base URL: `https://api.meet-align.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.meet-align.com/api/me/conversations/{conversation_id}/attachments`
- Auth: none declared

The composer's "Add files" — a real chat-native attachment, NOT
an Align Doc (see 0025_chat_attachments.sql's docstring for why this
exists instead of routers/documents.py's `/upload`). Two-step, same
shape as that endpoint's own callers: upload first (this), then
POST the message with `attachmentId` — the message doesn't exist
yet at upload time, so nothing here can attach itself to one.

## Path parameters

- `conversation_id` string, required

## Response `200`

Successful Response

- object

## Other responses

- `422`: Validation Error
