What you need to know about WhatsApp Business User Engagement

• Businesses may only contact people on WhatsApp if: (a) they have given you their mobile phone number; and (b) they have agreed to be contacted by you over WhatsApp. You are solely responsible for providing appropriate notices and disclosures to, and obtaining appropriate consents from, people.
• In order to send a WhatsApp message to a person, you must receive opt-in permission in-line and contextually during the relevant user flows. For example, to receive a receipt via WhatsApp, a person must opt in during a purchase flow. Opt-in obtained without context and in any manner not related to an action the user is already taking, does not comply with this policy.
• Opt-in permissions must display a visual element (e.g. a check box) next to the WhatsApp name and logo, with adjacent language clearly stating: (a) what type of information you will send to your customer; and (b) that you will message it via WhatsApp. You must give the person control over which WhatsApp number is used for the opt in, such as by giving the person the ability to edit the phone number.
• Businesses must respect all requests (either on or off WhatsApp) by a person to block, discontinue, or otherwise opt out of communications from you via WhatsApp, including removing that person from your contacts list.
• Businesses may only contact children on WhatsApp in compliance with applicable law.

Businesses must familiarize themselves with WhatsApp Commerce policy
