Customer messaging
WhatsApp
WhatsApp Business is WhatsApp's (Meta) offering for companies, and it comes in two versions. The WhatsApp Business app is free and built for small businesses: a business profile, a product showcase and automated replies, with limited customization and integration. The WhatsApp Business Platform is for medium and large businesses: it gives API access to message customers at scale, connect other systems and send template messages, which are billed per message.
Confirm appointments, send reminders and answer patient questions on the channel they already use.
