Customer.io Core Features

Overview

Implement Customer.io's key platform features: transactional emails/push (password resets, receipts), API-triggered broadcasts (one-to-many on demand), segment-driving attributes, anonymous-to-known user merging, and person suppression/deletion.

Prerequisites

• customerio-node installed
• Track API credentials (CUSTOMERIO_SITE_ID + CUSTOMERIO_TRACK_API_KEY)
• App API credential (CUSTOMERIO_APP_API_KEY) — required for transactional + broadcasts

Instructions

Feature 1: Transactional Email

Transactional messages are opt-in-implied messages (receipts, password resets). Create the template in Customer.io dashboard first, then call the API with data.
