Before Editing Entity
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).
"Before Editing Entity" runs in GoZyncHosted right before the record is pulled. This is usually used to "seed" some data into the hosted record before it comes down.
