Passing the Consent String to a vendor
The IAB TCF specification is designed in a way so that vendors can automatically fetch the consent information from the CMP using the IAB TCF JS API. In case a vendor can not fetch the string (e.g. because only an <img> is implemented and not a <script> or <iframe>) you can use the following example script to fetch the relevant data:
<script>
var tcstring = "";
__tcfapi('getTCData',2, function (x,s){
if("tcString" in x)
{
tcstring = x.tcString;
}
});
document.write('<scr'+'ipt src="https://www.adserver.de/banner?gdpr_consent=' + tcstring +'&gdpr=1"></sc'+'ript>');
</script>
