WhatsApp usernames and business-scoped user IDs
WhatsApp is launching usernames in 2026, allowing users to display a username instead of their phone number. To support this change, Meta introduces a new identifier called the business-scoped user ID (BSUID). BSUIDs begin appearing in webhook payloads and will be supported as recipient identifiers in send requests starting in June 2026.
Warning
Breaking change: The from and to fields in Advanced Messaging events may now be empty when a user hides their phone number. Update your event handlers to use the new fromBSUID and toBSUID fields. For more information, see WhatsApp usernames and BSUIDs.
