Customer.io Connector

Last updated: Nov 07, 2022

What does the Customer.io Connector app do?

The Customer.io Connector sends event data from PostHog into Customer.io. User emails will also be sent if available and customers will be created in Customer.io.

What are the requirements for this app?

The Customer.io Connector requires either PostHog Cloud, or a self-hosted PostHog instance running version 1.30.0 or later.

Not running 1.30.0? Find out how to update your self-hosted PostHog deployment!

You'll also need access to the relevant Customer.io account.

How do I install the Customer.io Connector app?

Visit the 'Apps' page in your instance of PostHog.
Search for 'Customer.io' and select the app, press Install.
Add your Customer.io site ID and token at the configuration step.
Enable the app and watch your 'People' list get populated in Customer.io!

Configuration

Option	Description
`Customer.io Site ID` Type: string Required: True	Provided during Customer.io setup.
`Customer.io API Key` Type: string Required: True	Provided during Customer.io setup.
`Tracking Endpoint` Type: choice Required: False	Use the EU variant if your Customer.io account is based in the EU region.
`Filtering of Anonymous Users` Type: choice Required: False	Customer.io pricing is based on the number of customers. This is an option to only send events from users that have been identified. Take into consideration that merging after identification won't work (as those previously anonymous events won't be there).
`PostHog Event Allowlist` Type: string Required: False	If this is set, only the specified events (comma-separated) will be sent to Customer.io.

How do I match persons in PostHog with customers in Customer.io?

We assume that you use the same ID to identify users in Customer.io as you use as distinct_id or in posthog.identify().

How do I set properties on a Customer.io customer via PostHog?

PostHog will send any property inside the $set: {} property to customer.io. In the example below, email and userProperty will be set on the customer

JavaScript

posthog.capture(
  'some event',
  {
    event_property: 'this will not get sent',
    $set: {
      email: 'test@example.com',
      userProperty: 'value'
    }
  }
)
