The checkout banner is a Shopify-powered consent banner that enables end-users to make consent selections for Shopify consent categories from the checkout page for your Shopify store. The Didomi integration enables your organization to easily add a checkout banner that leverages the configured map between Didomi consent notice purposes and Shopify consent categories.

### Checkout banner mapping rules

In this section, we will cover some rules to keep in mind as it pertains to selections made via the checkout banner and its relationship to the mapping configured for the Didomi consent notice.

<table data-header-hidden><thead><tr><th width="283.166748046875"></th><th></th></tr></thead><tbody><tr><td>Updates to consent notice purposes</td><td>Any selections/updates made through the checkout banner will automatically update the consent notice purposes and Shopify consent categories initially set via the Didomi consent notice.</td></tr><tr><td>Missing consent notice purpose mapping</td><td><p>If a consent notice purpose is not mapped to a Shopify consent category, your organization's checkout banner will still be displayed.</p><p>End-users can make selections on Shopify consent categories that will then update consent notice purposes and/or vendors (see below) according to your configured mapping</p></td></tr><tr><td>Updates to consent notice vendors</td><td>In order to enable a vendor in your consent notice from the checkout banner, an end-user will need to enable all of the Shopify consent categories that map to the consent notice purposes used by the vendor.</td></tr></tbody></table>
