To uninstall the BigCommerce <> Drip integration, there is just one step you need to take. Uninstall the integration:
Log in to your BigCommerce account and go to Apps > My Apps > Drip: Email Marketing
Click Manage the integration
You’ll be taken to the BigCommerce integration page in Drip
The integration will be disconnected. New customers, orders, and revenue will not be shown in Drip, and your product catalog will be removed from Drip so you will not see them in segments or emails.
