Authorize your apps
In order to use PieSync, you need to have registered accounts with the apps you selected. At this point you'll need to connect PieSync to these apps so we can fetch the contacts data configuration. You need to do this for both apps.
While the screenshots below are some examples, the instructions for your app are listed separately on this page.
If it is your first time using PieSync, you will need to authorize both apps, one after the other.
If you have previously set up a connection with any of these apps, you can choose to re-purpose that authorization. Of course, you can also choose to login to your apps with a different account too.
