# Oauth Twitch Callback

`GET /api/oauth/twitch/callback`

## Request

- Base URL: `https://sleipnir.tv` (the document declares no server; this is the origin it was published from)
- URL: `https://sleipnir.tv/api/oauth/twitch/callback`
- Auth: none declared

Twitch redirects here with code+state. Exchange code for tokens,
fetch the Twitch user profile, save (replacing any existing active
connection for this Sleipnir user), redirect to account page.

Shared by the chat-connect and destination-connect flows: a dest grant
is recognised by its state matching the ISOLATED dest state store. If so,
we handle the destination and return; otherwise we fall through to the
chat logic below, unchanged.
