Connect your own keys.
Everything you enter here stays in this browser's local storage — Dispatch never sees or stores your keys on a server.

Calling backend
This should point at a backend you run yourself that exposes /voice-token and /appointments — see the Guide for what those endpoints need to return.
Dialer
Your Twilio Account SID, API Key/Secret, and TwiML App SID stay on your backend — they're never entered here, since a secret key in the browser can be read by anyone. Your backend uses those to sign the voice token that /voice-token returns.
Calendar (Google Meet)
This is a public OAuth Client ID, not a secret — created free in Google Cloud Console → Credentials (OAuth client ID → Web application, with this site's URL added under Authorized JavaScript origins) with the Google Calendar API enabled on that project. Connecting signs you in with Google and asks permission to create events with a Meet link on your calendar — that permission lasts about an hour per session, then you'll reconnect.
