First Zync
These are the notes for GoZync 3. Docs for the latest version of GoZync--GoZync 4--can be found here. GoZync 4 is a free upgrade and is highly recommended (hint: it's faster).
Testing your first sync
Once you've completed the integration for one table, you can test your sync. While you'll eventually want to test this from your iPhone, iPad, or laptop (offline) to your host/server, you can start testing right now, in FileMaker Pro, with all the files opened by the same copy of Pro.
(Remember, GoZync doesn't need FileMaker Server, so you can test it in Pro as you're developing.)
Turning on Testing Mode
If you have more than a hundred records to sync, you may want to set Testing Mode to "ON" n the upper right of the dashboard layout of GoZyncHosted.
Testing Mode was introduced in version 3.171
Testing Mode restricts the sync to consider just the last 5 records in your table as having changed since the last sync. This can make troubleshooting much quicker as you don't have to wait for long syncs (such as after hitting "reset" in GoZyncMobile).
Zync It!
1. In your mobile file, navigate to the layout selected for syncing in step one of Tab 1 of 4. Enter browse mode. Make a new record on this layout and fill out a few fields – or if you're pulling records only, make a new record in the corresponding table of your hosted file.
2. Still in your mobile file, open scripts and find the script "Zync It - This Table" inside the folder "GoZync".
3. Run that script. In FileMaker Pro you'll see a progress bar as the sync completes. In FileMaker Go you'll see a spinning busy icon.
4. What happens next depends on the Zync Options you set for your table.
