Klaviyo Hello World

Overview

Minimal working example: create a profile, track an event, and query the result using the klaviyo-api Node.js SDK against a.klaviyo.com/api/*. This is the smoke test that proves your API key, SDK install, and network path all work end-to-end before you build anything real.

Prerequisites

• Completed the klaviyo-install-auth setup so credentials are in place.
• KLAVIYO_PRIVATE_KEY exported in your environment (a private API key with Profiles and Events scopes).
• klaviyo-api installed in the project (npm install klaviyo-api).
• tsx available to run the TypeScript file (npx tsx …).
