If you want to stop using Supermetrics with your HubSpot account, you can request removal of the integration and deactivate your connection from the Supermetrics Hub.
Note that the instructions in this article apply to situations when you no longer want to use Supermetrics and want to disconnect your HubSpot account completely.
Instructions
On the Supermetrics Hub, go to Data sources under Connect.
Select the HubSpot data source.
Click the x icon to disconnect the data source.
Click Disconnect to confirm disabling the connection.
The connection now appears under Inactive Connections. Use the toggle under the list of logins to show the inactive connections if they aren't visible.
Click the trashcan icon to fully remove the connection.
Click Delete to complete the process. Supermetrics will uninstall the integration from your HubSpot account in the background.
You can verify the uninstallation in the Connected Apps page in HubSpot and see that the Supermetrics integration is no longer listed.
You can also uninstall the app directly in HubSpot following these instructions.
Note that if any other users have been using the integration on that account, those connections will now fail for lack of authorization. Follow the connection guide steps to reinstall the integration.
