I am using the API to send a share email, the post returns the AliasId of the share and I store it in my database. Now I want to go back, and use the AliasId and the email of the recipient to check if the file has been downloaded. However I cannot find any way to find the email of the user via share alias id. How do I get a list of share recipients and their emails? Is their an alternate or more straight forward way to see if files were downloaded by email?
