# Callback

`GET /auth/callback`

## Request

- Base URL: `https://contendeo.app` (the document declares no server; this is the origin it was published from)
- URL: `https://contendeo.app/auth/callback`
- Auth: none declared

Handle Supabase's redirect back to us after user logs in.

Supabase returns the access/refresh tokens in the URL fragment, so this
route serves an HTML page that extracts them via JS and posts them to
/auth/finalize, which then redirects back to Claude with our code.

## Response `200`

Successful Response

- unknown
