This function is used to retrieve the users' consent. It is part of the IAB Europe Transparency and Consent Framework (TCF) Specifications.

Syntax

function __tcfapi()

...

In order to retrieve user consent, the IAB specification provides two different functions: addEventListener and getTCData. Although both can retrieve user consent, addEventListener is recommended, given it can "follow" the user interaction, making sure that it will eventually return the consent data once the user has finished interacting with the CMP GUI. On the other hand, getTCData function just returns the current consent status. This means that it may return uninitialized, incomplete, or full consent data, depending on the timing it is called. This means that the responsibility to obtain the definite data for the consent falls over the publisher publisher’s lap. With addEventListener every consent status change triggers a new call to the given callback, which means that the only thing needed to process the consent data is a simple check for whether or not that consent data is final, thus usable down the line.

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