Returns the contacts the token's user can see, 25 per page (use page to move through them),
sorted by last name and then first name unless you choose another sort. Users who can see all
records get every contact in the company. Sales users get contacts assigned to them or on their
own leads and jobs, and production managers get contacts on the jobs they manage.

Besides the parameters below, you can filter with lifecycle_stage (prospect or contact),
email_opt_in=true, sms_opt_in=true, or letter (the first letter of the last name, falling
back to first name or company name).
