# TCF 1.1/2.0

{% hint style="danger" %}
**Voorlopig is deze functionaliteit nog in de experimentele fase. Elke implementatie van TCF zal niet effectief zijn**
{% endhint %}

Het [consent management platform (CMP) framework](https://github.com/InteractiveAdvertisingBureau/GDPR-Transparency-and-Consent-Framework) wordt momenteel ondersteund door de Dastra-widget. Om de opt-in voor IAB-verkopers te activeren, ga je naar het gedeelte "services" van de widgetconfiguratie en activeer je het betreffende vakje.

Zodra het vakje is aangevinkt, kun je de veranderingen zien in de interface van de widget:

Automatisch, wanneer de IAB optin wordt uitgevoerd, wordt de cookie met de gecodeerde informatie over de toestemming van de gebruiker voor IAB-verkopers automatisch aangemaakt in de browser:

{% hint style="info" %}
Deze cookie heeft een standaard levensduur van 180 dagen en heet "eupubconsent".
{% endhint %}

### De toestemmingsstring van IAB vastleggen

Wanneer de gebruiker toestemming geeft, is het mogelijk om de toestemmingsstring direct vast te leggen met de volgende event listener:

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

# Agent Instructions
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/nl/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.
