# TCF 1.1/2.0

{% hint style="danger" %}
**Pour l'instant, cette fonctionnalité est encore en phase expérimentale. Toute implémentation du TCF ne sera pas effective**
{% endhint %}

Le [consent management platform (CMP) framework](https://github.com/InteractiveAdvertisingBureau/GDPR-Transparency-and-Consent-Framework) est actuellement supporté par le widget Dastra. Pour activer l'optin des vendors de l'IAB, il vous suffit de vous rendre dans la partie "services" de la configuration du widget et d'activer la case correspondante.

Une fois la case cochée, vous pouvez observer les modifications dans l'interface du widget :

Automatiquement, lors de l'optin de l'IAB, le cookie contenant les informations encodés sur le consentement de l'utilisateur aux vendeurs de l'IAB sont automatiquement créées dans le navigateur :

{% hint style="info" %}
Ce cookie a une durée de vie par défaut de 180 jours et est nommé "eupubconsent"
{% endhint %}

### Capturer la chaîne du consentement de l'IAB

Lorsque l'utilisateur applique son consentement, il est possible de capter la chaîne du consentement directement en utilisant l'écouteur d’événement suivant :

```javascript
document.addEventListener('dastra:consentstring',function(consentString){
    console.log(consentString); // BOybBVKOybbNhABABBENCoAAAAAq6AAA
});
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.dastra.eu/features/gerer-le-consentement-aux-cookies/integration-technique/iab-et-cmp.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
