# Event Deduplication

### What is deduplication?

When you are sending events via both the Pixel and Conversion API, there are often 2 events sent for 1 user action.

### Should I be worried about duplicated events?

{% hint style="info" %}
**Two Owls solves duplication problem:** Just turn on Conversion API as you wish, because we have done all things necessary to ensure Facebook can deduplicate your events.
{% endhint %}

First, let's understand that deduplication works depending on:

* The event’s name
* The event’s ID

:tada:Two Owls events already contain these, and browser events and server events shared both the event ID and event name, that's how Facebook will deduplicate them.

Check this out to confirm if your events are deduplicated properly:point\_down:

## 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.twoowls.io/hot-topics/conversion-api-events/event-deduplication.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.
