Customer.io receives Zippendo shipping and order events so you can trigger campaigns. The catalog card copy is: Trigger Customer.io campaigns from shipping events. This page is the Customer.io connect form. Shared chrome: Connect an integration. Inventory: Connect a carrier or integration. Conditional logic: Automations. Provider essay: Customer.io. Creating a connection uses the same plan gate as outbound webhooks (Growth and above). Nordlys on this page is Pro, so Connect is unlocked.

​
Prerequisites

  • Customer.io Site ID and API Key.
  • Whether the workspace uses the US or EU data region.

​
Where to get Site ID and API Key

Zippendo uses Customer.io Track API credentials (Site ID + API Key). Creating them is Workspace Settings → API and webhook credentials in your account (login required). The public docs page below explains the Track API and those two values.
Customer.io Track API integrations docs explaining Site ID and API Key

Connect from Catalog

1

Open Catalog

Sidebar Integrations. Page title Integrations. Description: Connect downstream tools to receive shipping and order events from Zippendo. Tabs: Connected (?tab=connected) and Catalog (?tab=catalog).

3

Click Connect

5

Connect

Connect stays disabled until Connection Name, Site ID, API Key, and Data Region are stored. The region select shows US (track.customer.io) before you touch it, but you still have to open the select and pick US (track.customer.io) or EU (track-eu.customer.io) so the value is saved. Success toast: Integration connected successfully. Failure: Failed to create connection (or This feature is not available on your current plan.).

Shared fields

These appear on every integration connect dialog, including Customer.io.

​
Customer.io credentials

Footer: Cancel / Connect.
The wrong Data Region causes authentication failures on delivery. EU workspaces must use EU (track-eu.customer.io).
Event Name Override exists on the API (eventConfig) only. It is not a field on Connect or Edit. Override the name from an automation inspector instead — Automations.

​
Auto-send events Customer.io supports

Groups shown: Shipments, Orders, Tracking. Not on this modal: Shipment Updated, Shipment Error, Order Cancelled.
