Can anyone tell me that I am getting GUID of my connections. Is there any way to get Yahoo Mail ID by this GUID? YQL or any other API
GUIDs are public part of a profile whereas the email id and other details are the private details. To prevent spamming and inadvertent leakage of this information, you can only go in one direction from a yahoo id to a guid. The other way i.e getting an email address from a GUID is not supported. In other words, given that you already know a persons email id, you can use it find the guid and thus the social.profile.
