PieSync requires your table in Airtable to be structured in a certain way to maintain stable syncing.
- an email field in email format
- a field to capture last modified time
You'll need to point to these two fields during the setup & authentication phase of your Airtable sync.
Your table needs to have an email field. PieSync will typically sync to what is called a contact in your other app, and it relies on the email to initially match pre-existing contacts.
Make sure this is an actual email field - it cannot be a text field that happens to contains emails.
Last modified timestamp
To enable syncing, your table needs to have a last modified timestamp field. PieSync relies on this information to maintain the sync - it's absolutely crucial this field remains an integral part of your table.
Keep the default settings which are that the field updates with all editable fields and that it has a time component.
It's recommended to give this a recognizable name, and to hide it.
