Communication
Setup
User-supplied API key

Setup

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

Build with Sendblue

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