Description of how to interact with IAB consent API
If you are using IAB TCF option (see this page to setup IAB TCF on your account), you will be able to use IAB TCF's __tcfapi where your privacy banner is deployed.
That function is defined in your container and in your privacy banner so that you can use it before your privacy banner has finished loading. It is sometimes referred by IAB as the TCF API stub.
IAB TCF consent is encoded in a format called the Consent-String.
How to use the TCF API
The recommended way of getting the value of TCF's consent-string (tcData.tcString in the example below) is by using the addEventListener command.
This an optional extension to IAB TCF.
Once setup in TrustCommander Options, an additional addtlConsent property will be available on the tcData object.
