I intend to use API to update this field but I’m not getting its value when searching for zurmo_synced: false. When running User.find(3) on Zammad console for example I get:
The reason is, because you’re forbidding your customers, agents and admins to see this field.
The API won’t show this field, because it’s accessing the data sets as the user you’re referencing.
Please note that rails console and API might differ in usuage and (even more important) on what you see.
Allow either agents or admins (depending on what role your API user does have) to view the field and you should be fine.
