Working with Consent Scopes / Cross Domain Consent
Consent Scopes allow you to define in which "area" a consent or rejection is valid. You can set this setting in menu under Legal settings > Consent Scope. The most common use of consent scopes is the so called "Cross Domain Consent".
Note: Modern browsers will partition the cookies based on the top window domain. In this case Cross domain consent is NOT possible.
The following scopes can be used:
| Consent Scope | Cookie Names | Description | 1st Party Cookies | 3rd Party Cookies |

Custom Consent Scopes (Enterprise Package only)
A custom consent scope allows you to share consent information across multile CMPs in your account. In order to use it, go to CMPs > Edit > Show advanced settings > Consent Scope and click on Add new scope. Give the new scope a name and press save. Once done, you will find the new consent scope in the select box in your CMP settings. You can now use the same consent scope in multiple CMPs. All CMPs that use this same consent scope will automatically share the consent information with the other CMPs.
Further cross domain strategies
In addition to the above consent scope setting, websites can use other features to share consent across websites or apps:
Cross-Domain Consent via Cookie Wall
Cross-Domain Consent via Consent Sync on click-out
Cross-Domain Consent via manual sharing of consent
Further cross domain consent sharing can be done by manually sharing the consent data. This makes sense in situations when the user is logged into the website and switches to another website where the user is also logged in. More information can be found here.
