Meta for Developers Free Beginner

Meta's policy page on the permission a business needs before it messages someone on WhatsApp, and the ways that permission can be collected.

  • A business must get opt-in before messaging people on WhatsApp and must have their mobile number.
  • The opt-in must say clearly that the person is opting in to messages from the business, and name the business.
