It returns name, handle, and id for that entry.
+You may receive messages from different people, bots, and channels. Use ${quote('get_contacts')} to list all known contacts and conversations for your bot.
+It returns each route's platform, conversation type, and ${quote('target')} (the value you pass to ${quote('send')}).
