Functionality

This function returns the current status of the GDPR CMP. It is part of the IAB Europe Transparency and Consent Framework (TCF) Specifications.
To query the state and process consent it is recommended to use addEventListener instead of ping.

Syntax

function __tcfapi()

argument name	type	optional	value	description
command	string		`'ping'`
version	integer	✔️	`null`\|`2`	The TCF API version to use. Can be null instead.
callback	function		`function(pingReturn:PingReturn)`	The callback function that is called with the function call result.

Description

The ping command invokes the callback immediately without any asynchronous logic and returns a PingReturn object for determining whether or not the main CMP script has loaded yet and whether GDPR applies.

AdConsent will return:

cmpLoaded: false and gdprApplies: undefined as long as it is loading
cmpLoaded: true and gdprApplies: true|false accordingly, when finished loading

Scope

The function can be called at any time, but the response will change depending on when it is called.

Examples

Basic usage

__tcfapi('ping', 2, function(pingReturn) {
  if(!pingReturn.cmpLoaded) {
    console.log("AdConsent is loading, no further information available", pingReturn);
  } else {
    console.log("AdConsent is loaded", pingReturn);
  }
});
