WhatsApp Business is a service for having a dialogue with customers using the WhatsApp messaging service. It can be used to send messages to customers and for responding to customer-initiated conversations over WhatsApp. The service is provided by WhatsApp and other providers, and is accessible using an API or portal service.
Melrose Labs will be providing customers with the ability to send and receive messages with WhatsApp users later in 2020.
