Get Masked Backup Email
View All WhatsApp Number Validation & Profile Lookup APIs →Fetch the masked backup email from WhatsApp registration metadata (e.g. u*******6@gmail.com). This is not a business-profile contact email. Two-step flow: call Check WhatsApp Account Exists first; only call this when hasExtra lists "email". Pass the returned userHash here — the number is resolved server-side. Invalid/expired userHash is rejected without hitting upstream. When the field is absent, email is null and message explains why.
