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:

  • A business’ reply to a user message is delivered

The 24-hour conversation session is different from the 24-hour customer support window. The customer support window is a rolling window that is refreshed when a user-initiated message is delivered to a business. Within the customer support window businesses can send free-form messages. Any business-initiated message sent more than 24 hours after the last customer message must be a template message.
