__tcfapi function - getTCData command

In this article we will cover the IAB __tcfapi() function with the getTCData command. Your organization can use this command to retrieve end-user consent data for IAB purposes, vendors, legitimate interest, publisher restrictions and more. The IAB has more information about the getTCData API command.

the getTCData command

The getTCData command can be called with the following example:

getTCData command

__tcfapi('getTCData', 2, function(tcdata, success) { console.log(tcdata); });

Example implementation

Your organization can call the getTCData command through the browser console or Javascript code on a webpage. The command returns the end-user's consent as a data object.

With browser console Javascript code

Once your organization's website has loaded enter this command directly into the browser tools console window and press enter:

__tcfapi('getTCData', 2, (tcdata, success) => {
   console.log("show tcdata: ", tcdata)
});

API response

The response is an end-user's consent data object with the following information:
