Working with Legal Bases

The CMP allows you to set the legal basis per vendor and purpose. Depending on the setting, the behavior of the CMP will be different.

Please note: When using the IAB TCF v1 or v2, only default, consent and legitimate interests are supported in the signals sent to vendors.

If a purpose and a vendor are set to a legal basis other than the default legal basis, the setting of the vendor takes precedence:

The default setting is, that the CMP will always display only one toggle for each vendor and each purpose. Enabling or disabling a toggle will always enable/disable consent AND legitimate interest for this vendor or purpose. If you wish to offer two separate choices, you can do so under Menu > CMPs > Edit > Legal Settings > Legal Bases:

Once enabled, the CMP will show two toggles for each vendor/purpose when you click on the questionmark icon.

Default settings (one toggle for each purpose):
