Meta deprecated the On-Behalf-Of (OBO) account ownership model for WhatsApp Business API, replacing it with partner-initiated WABA creation. The last day to onboard customers using OBO was September 29, 2025, and the final deadline to transfer existing OBO WABAs to business customers was October 1, 2025. The new model provides direct account ownership and access to features like Marketing Messages Lite API.
