Configuration

When connector is authorized against Customer.io API, it’s time to define what data exactly will be send and received from Customer.io.

Sending Users

Start with Outgoing Mapping section in the settings.

The most important decision you have to make here is which user attribute to send as the **customerId** to Customer.io which is the unique identifier within Customer.io. Our recommendation is to either use the external_id if you assign your own identifier to users in Hull or use the Hull id.

To send users to Customer.io, first define which whitelisted segments users will need to belong to. If the segments are not specified, users will not be sent to Customer.io. Second, specify which attributes will be sent from Hull to Customer.io. By default, the attributes email, customerId and hull_segments (all the segments the user belongs to) will be sent to Customer.io.

IMPORTANT: Please keep in mind that Customer.io API allows to send maximum 30 attributes per API call so bigger number of selected attributes will double the number of API calls and can make the connector slower.

When users leave all whitelisted segments, you have to ability to remove that user from Customer.io. To enable this feature, toggle on enable user deletion and the connector will automatically remove users from Customer.io if they no longer belong to any of the whitelisted segments. Otherwise, if a user leaves all whitelisted segment it will be kept in Customer.io, but will no longer receive updates.

Furthermore, you can specify which events will be sent to Customer.io by selecting the events from the dropdown list. By default no events are sent. Each outgoing event will create a new activity in Customer.io. For all events except Page View Events (see below), the activity type will be set to “Event” and the activity name will have the same name as the Hull event, which allows basic segmentation in Customer.io.

Sending Page View Events

Customer.io allows you the option to handle Page View Events differently than generic events. To begin sending these events to Customer.io, in the connector settings, add the page event to whitelisted events list. The connector will then send all future Page View Events to Customer.io as activities. Unlike generic events, the type of the activity will be set to “Page” and the name of the activity will be the url of the Page View. This is aligned with Customer.io documentation on tracking page views and allows you to build more fine grained segments in Customer.io. The url of the Page View activity will be picked from Hull Event url property, or, if not available, will fall back to the page_url context property. Additionally, a referrer will be added to the Customer.io activity.

Sending Anonymous Events

You can also activate Anonymous Events, which is an advanced feature in Customer.io. If you are not familiar with this feature, please refer to Customer.io’s documentation.

Optional - receiving subset of Customer.io events

You are able to limit the events Hull will receive from Customer.io. The list of all events is available in the Customer.io docs under https://Customer.io/docs/webhooks#events.

To customize this list, navigate to your Customer.io dashboard, select Integrations from the menu on the left, and navigate to Email Activity Webhook card:
