# Performance tab (Event Match Quality)

<figure><img src="/files/Kt09IlYixWFXMmNdCc7g" alt=""><figcaption></figcaption></figure>

The Performance tab can now display Event Match Quality insights, coming from Facebook. It represents the matching quality, referring to the quality of events sent (completeness of data, like events with email, phone, fbp, fbc...). More identifiers are present on events sent, better is the score.

First, select (or login) the Facebook account to which belongs the pixel defined in the Settings step.

{% hint style="info" %}
Facebook accounts can be managed on Administration / Connector credentials
{% endhint %}

You can click on a specific event to get more details about the score.

For each event, you can get the details of matching keys and the corresponding volume (%).

This information is also available on Facebook Business Manager interface (Events Manager).

## 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://doc.commandersact.com/features/destinations/destinations-catalog/facebook/facebook-conversions-api/performance-tab-event-match-quality.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.
