Session messages are the replies a business sends while a customer service window is open. They can contain any content: text, images, documents, buttons, because the customer recently messaged first.
They contrast with template messages, which are required to start a conversation or to message a customer once the 24-hour window has closed.
Session messages are central to support and conversational selling, where an agent or chatbot answers in real time. Their billing follows the conversation pricing rules in effect for the customer's market.
