What is WhatsApp opt-in?

Opt-in is the permission a person gives a business to contact them on WhatsApp. Meta's policies require it for business-initiated messages, and it's the best protection against reports.

Where to collect it

• A checkbox on forms and checkout pages.
• During the conversation, asking if they'd like to receive updates.
• When the customer writes to you first about a specific topic.

Good practice

• Say what kind of messages they'll receive.
• Offer an easy way to stop.
• Don't reuse permission given for one purpose for unrelated campaigns.
