Get Device / Owner Name
View All WhatsApp Number Validation & Profile Lookup APIs →Fetch the owner display name decoded from the WhatsApp registration cert (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 without hitting upstream. 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
Gateway-validated userHash Invalid or expired tokens are rejected before any upstream call
Cache-aware Upstream is cache-first; response includes cached flag and age when served from cache
