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

Describe one task you want your app to perform with Sendblue. Check the connection requirements, then verify the result in your app. Building and running the feature may use credits; review current pricing.
