# Customer.io

Customer.io integration enables you to send user data and events directly from your server to your Customer.io workspace. This server-side connection allows you to track customer actions, update user profiles, and trigger automated campaigns reliably without depending on the user’s browser. Once configured with your Customer.io credentials, events and user attributes can be sent seamlessly to power personalized messaging and workflows.

### Details

Channel name: [customer.io](http://customer.io)

Server API version: v2

### Event Flow

Our Customer.io integration sends the events from your website to Customer.io via server API;  we do not load the Customer.io browser script.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.edgetag.io/channels/customer.io.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
