Fetch Event API

The fetch event API allows admins to fetch an event regardless of their membership in the room it originated in.

To use it, you will need to authenticate by providing an access_token for a server admin: see Admin API.

Request:

GET /_synapse/admin/v1/fetch_event/<event_id>

The API returns a JSON body like the following:
