WhatsApp defines a conversation as a 24-hour session of messaging between a person and a business. There is no limit on the number of messages that can be exchanged in the fixed 24-hour window. The 24-hour conversation session begins when:

The 24-hour conversation session is different from the 24-hour customer support window.
