In the Confirmation step of the setup process, you will be able to review your configuration for each step of the setup process. Double check each aspect here: if you see something that isn't quite right yet, you can return to that part of the setup process.
If you are happy with your pull mapping, your pull criteria and your push mapping, you can go ahead an Save your setup. If you have chosen manual pulling only, you can go ahead and pull your first data using 'Save and upload'. If you have enabled automatic pulling, CustomerGauge will start checking your system and pulling data from your chosen start date, with the frequency you indicated. Either way, all uploads will appear under the API tab of the Upload List, which you can find in the In-App Upload menu item.
