# Facebook Conversion API vs. Facebook Pixel

### Facebook Pixel

* **Définition** : Un script qui suit les activités des utilisateurs sur un site web via le navigateur.
* **Fonctionnement** : Suivi client via des cookies.
* **Limites** : Bloqué par les bloqueurs de pub et les restrictions sur les cookies tiers.

### Facebook Conversion API (CAPI)

* **Définition** : Suivi côté serveur pour une meilleure précision des données.
* **Avantages** : Résistant aux bloqueurs de pubs et permet d'utiliser des cookies propriétaires.

### Différences clés

* **Suivi côté client vs côté serveur**.
* **Contrôle des données** : CAPI offre plus de contrôle.
* **Résistance aux bloqueurs** : CAPI est plus robuste.

### Conclusion

## 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://server-side.docs.sirdata.net/sirdata-server-side/f.a.q-server-side/facebook-capi/facebook-conversion-api-vs.-facebook-pixel.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.
