# The importance of Conversion API

{% hint style="warning" %} <mark style="color:orange;">Meta Pixel: Since Pixel relies on cookies to collect data, it can be affected by browser restrictions (Ad Block, iOS 14, etc.) and user cookie preferences. This can limit its effectiveness in tracking user interactions, causing you to miss many user events.</mark>
{% endhint %}

{% hint style="info" %}
**Conversion API**: This tool offers a more privacy-friendly solution. Since it sends data directly from your server to Facebook, it bypasses the browser and is less affected by cookie restrictions.
{% endhint %}

### Advantages of using Facebook Conversions API

The Facebook Conversions API has several advantages over the Facebook Pixel.

#### No hassle of Cookie-blocking

One of the most significant advantages is that it’s not affected by cookies or ad blockers. This means you can track user behavior even if they’re using an ad blocker or have disabled cookies on their browser.

**Data privacy**

Another advantage of the Conversions API is that it’s more reliable than the Pixel because it sends data directly to Facebook’s servers. This means you can get more accurate data on user behavior, which can help you make more informed marketing decisions.

#### Detailed Insights

Facebook Conversions API offers a high level of flexibility, allowing you to track custom events that are most relevant to your business. For instance, if you operate an e-commerce store, you can track events such as product views, add-to-cart, and purchases. This level of customization empowers you to gather more detailed information on user behavior and make more informed marketing decisions.

## 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://zotek.gitbook.io/facebook-multiple-pixel/hot-topic-and-troubleshooting/pixel-issue/the-importance-of-conversion-api.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.
