ActiveDEMAND has outstanding native integration with woocommerce. One question that has been asked is 'how can i access the woocommerce features ... I do not see them in the ActiveDEMAND Wordpress plugin?'.
Things to check
The Woocommerce integration requires at least one webform in ActiveDEMAND to be defined. If you do not have a webform created in ActiveDEMAND, you will not be able to post data from Woocommerce cart changes.
Is the woocommerce plugin on the website up to date and enabled? The ActiveDEMAND WP plugin requires the Woocommerece plugin to be enabled.
