# The default Client IDs above ONLY work when OmniRoute runs on localhost.

#   1. By default, the browser will attempt OAuth redirects back to localhost, which will fail.
#   2. Set NEXT_PUBLIC_BASE_URL=https://your-domain.com to fix the redirect URI.
#   3. You MUST create your own OAuth App in each provider's developer console (Google Cloud, etc.)
#      and set the Authorized redirect URI to your domain (e.g., https://your-domain.com/callback).
#   4. Replace the _OAUTH_CLIENT_ID and _SECRET values above with your own credentials.
