CMP API usage (TCF v2)

Introduction

As an approved IAB Consent Management Platform, Clickio Consent Tool fully supports the standardized CMP Javascript API for user consent data retrieval.

The API is already widely used by different demand sources and mediation solutions to determine user consent state, so there may be no additional steps needed from the site owner to make it work and comply with the GDPR except for Clickio CMP code install.

Non-EU visitors and CMP API

By default, the non-EU version of the Consent Tool code (automatically served by our geo-aware CDN) does not include CMP API functionality (to minimize load traffic/time and boost web vitals), but that is server-side configurable - feel free to contact support if you need it.

General information

The current version API documentation can be found here. Clickio CMP API implementation fully supports all the described functionality.

When implementing the CMP API integration, you should bear in mind that it loads asynchronously, so you can not directly call __tcfapi function to pass commands from your scripts. Avoid implementing any await cycles/timeouts, which create parasitic load or delays. Instead, you can use a simple CMP API stub, which gracefully handles all the calls for you, while the full code loads.

The code must be installed in the top of the site page head section, before any ads codes and libraries.

We recommend installing the stub code on the site if you are using non-Clickio 3rd party monetization solutions. For directly installed plain Google ads tags please refer to this article.

The code is a subject to change, please be sure to have the latest version installed on the site prior to filing support requests in case of any issues.

After installing this code on the page, you can then call the API as usual (getTCData dump example is shown below).

window.__tcfapi('getTCData', null, function (consentData, consentDataSuccess) {
    console.groupCollapsed('getTCData called ('+consentDataSuccess+')');
    console.log(consentData);
    console.groupEnd();
});

The stub stores the request and replies as soon as the full code loads. PostMessage commands are also supported.
