Setup
User-supplied API key

Setup

You supply your own Twilio credentials as environment variables on your app — TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, TWILIO_PHONE_NUMBER. Add them under Settings → Environment Variables, mark them secret, and call Twilio from a server-side endpoint so the keys never reach the browser.

Build with Twilio

Open OverSkill, describe what you want to build, and reference Twilio in your prompt — the AI will wire up the integration automatically.
