Starting October 1, 2026, Meta has officially rolled out its strict new monetization structure for the **WhatsApp Business API**, altering global customer service workflows. Under the updated guidelines, the tech giant will stop delivering non-template service messages within open 24-hour windows for any corporate accounts or solution providers that fail to put a valid payment method on file. The implementation marks the end of free corporate customer service windows on the platform, establishing a standard per-message charging system intended to streamline commercial data flows and boost ad-platform revenues.
