To setup the data sync please visit your account settings page and click the 'Check Now' button next to the 'AutoReach Field Added to Activites' label. AutoReach will look for a field on the Activity object with 'autoreach' in the name and show a checkmark after a successful link is made. After successfully linking you'll be presented with a checkbox for enabling a daily auto sync of your AutoReach data (optional). If you'd prefer not to setup auto syncing you can sync at any time from the reports section of AutoReach.
