What is WhatsApp opt-in?
WhatsApp opt-in is a customer's explicit permission to receive messages from a business on WhatsApp. Meta requires you to collect opt-in before messaging someone, through any channel such as a website, app or checkout.
Why WhatsApp opt-in matters
Opt-in matters because messaging people who did not agree harms your quality rating and can get your number restricted. Clean, opted-in lists keep your messaging healthy.
Example
A checkout page with a ticked box reading get order updates on WhatsApp is a valid opt-in for that customer.
