What are the requirements for the Sugar Market integrations 'User', does it require full system admin or regular user with a Role with some admin permissions ?
In general, we do recommend the syncing user have admin privileges. If you wanted to use the syncing user permissions to gate what information the sync has access to, then limiting those permissions is an option. Essentially the system will only be able to sync what that the syncing user is able to access (within the normal sync options of accounts, contacts, leads, opportunities).
