Save Contact (In-App)​

WhatsApp now supports storing contacts directly inside the WhatsApp cloud rather than sync'ing to your phone's native address book. This allows for cross-device synchronization and prevents cluttering your device's contacts.

To save a contact inside WhatsApp, use saveContact:

// Save a contact with full name and mobile number (with or without @s.whatsapp.net)
await sock.saveContact("John Doe", "1234567890")
