Customer.io Hello World

Output

• A verified synthetic profile/event or message example in a non-production workspace.
• A minimal receipt showing environment, validation result, and cleanup without retaining recipient data.

Examples

Create a development-only profile using a synthetic identifier, submit one schema-valid event, and confirm its arrival in the development workspace. Remove the test profile or let its documented TTL expire. Never use a real customer email or production segment as a tutorial target.

Overview

Create a minimal working Customer.io integration: identify a user (create/update their profile), track an event, and send a transactional email. This covers the three fundamental Customer.io operations.

Prerequisites

• customerio-node installed (npm install customerio-node)
• CUSTOMERIO_SITE_ID and CUSTOMERIO_TRACK_API_KEY configured
• CUSTOMERIO_APP_API_KEY configured (for transactional email example)
