Frequently asked questions
Is it really two-way sync?
Yes! Whalesync offers true two-way sync. Unlike most apps that offer one-way syncs in two directions, Whalesync actually keeps your data in sync bi-directionally. Update data in one app and see it instantly to sync to the other (or vice-versa).
What does "live" update frequency mean?
Live means changes sync as soon as Whalesync hears about them. Where an app supports webhooks, that is moments after the change; where it does not, Whalesync scans on a schedule and picks changes up on the next pass. Every plan syncs at the same speed. Each connection defaults to the fastest frequency its app supports, and you can slow a connection down to save API quota but not push it past its default. The sync frequency docs cover each app.
What happens if my data has an error and can't be synced?
If data can't be synced (e.g. a required field is missing), Whalesync will alert you on the Issues page. This alert provides the exact error from your destination app and any other info that will help you fix the issue. In the meantime, Whalesync will continue to sync all data that doesn't have errors.
