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).
Why use auto processing?
The "round trip" option tells the mobile file to post its changes to the host and then process those changes. So why would you want to process changes with a server-side script instead?
The reason is speed. When the mobile file does the processing, it opens your hosted solution over its WIFI or 3G connection, and that can take a bit of time. It also means the processing is done on the (relatively) wimpy processor of your iPhone or iPad.
So it can be much faster to have the mobile file just push its changes, and then have a server-side script pick up those changes and process them every X minutes. (And because GoZync is transactional, you'll never have the server processing an incomplete record – a record that hasn't finished getting posted to the server.)
How can I process the inbox automatically?
You can process your inbox automatically by a) setting "Process Automatically" to "On" from the Inbox tab of GoZyncHosted, and b) setting up a FileMaker Server Script Schedule to run the script "Auto Processing" as often as you'd like to process records.
If you haven't added any additional scripting into GoZync's workflow, then you're done.
If you have added some workflow scripts, or changed the script "Default Set Field" in GoZyncHosted, there are a few server-side considerations to keep in mind regarding our auto-processing script and any scripts you have it call:
