Returns all of the contact IDs who have an associatedcompanyid property of :companyid. Useful if you're not looking for any more information on contacts at a company other than that they exist and where to find more information on them.

This will return 100 contacts by default, which is the maximum number of records you can get in a single request. You can get fewer contacts per request using the count= parameter. You can use the "vidoffset": field returned in the results with the vidOffset= parameter to get the next set of results.
