Getting opt-in for WhatsApp

From Meta for Developers 5 min read

  • 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.
  • Opt-in can be collected by SMS, on a website, through an IVR call flow, or in person or on paper.
  • Recommended: cover the categories of message you will send, give clear opt-out instructions, and honour them.
