Get Device / Owner Name
View all WhatsApp Number Validation & Profile Lookup endpoints →Fetch the available owner display name (typically only for currently active accounts). Two-step flow: call Check WhatsApp Account Exists first; only call this when hasExtra lists "deviceName". Pass the returned userHash here — the number is resolved server-side. Invalid/expired userHash is rejected. When the field is absent, deviceName is null and message explains why.
API Features
Owner display name Returns the name decoded from the WhatsApp /v2/exist cert when available
