OTP & authentication
Deliver one-time passwords as Meta authentication conversations — cheaper than SMS in most markets, with read receipts.
On Cloud API lets banks and fintechs deliver one-time passwords, transaction alerts and payment reminders over WhatsApp, using the official Meta Cloud API with 0% markup on Meta’s rates. OTPs are billed as Meta authentication conversations, which are typically far cheaper than SMS and deliver with read receipts. Every message is opt-in and sent from a Meta-verified business number, so it cannot be spoofed the way an SMS sender ID can.

It is not a certification — your own compliance team should review your use case.
