get https://api.shift.io/v4/sync/links//history
Returns a list of link recipients
This call requires a link id as a path parameter, and it returns the names and emails of anyone listed as a link recipient or anyone who has viewed the link. If the link was sent to a specific recipient, then the recipient is included in the response, whether or not they have viewed the link yet.
Anonymous viewers (viewers who are not logged into MediaSilo) are not returned. A link without recipients and without any views by named users results in a 200 code with an empty recipients object.
The response includes the created property, which indicates the time (in Unix time) when the link was created. If a recipient has uploaded a profile image, the avatar property provides a link to it.
