I would like to be able to recommend potential friends based on information that the user might have in their contacts, such as an email address or phone number.
I don’t see any API calls for this, but is it possible for server-side extensions to query the table of accounts based on this information, please?
In order to implement such feature, you need to store that information somewhere and this is PII(Personal Identifiable Information). Have you taken GDPR and Privacy Shield into consideration?
