# Get all messages in a thread

`GET /api/system-admin/inbox/threads/{thread_id}`

Fetch a conversation.

Capped at MAX_THREAD_MESSAGES. Bodies live only in S3, so every message in
the response costs a GET; `include_bodies` defaults to "all" purely for
backward compatibility with the current frontend.

## Path parameters

- `thread_id` string, required

## Query parameters

- `mailbox` string
- `include_bodies` string — Which message bodies to fetch from S3. 'latest' lets the client lazy-load the rest through GET /{id}.

## Headers

- `x-api-token` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses

- `422` — Validation Error
