Send a whatsapp message
If a WhatsApp user has sent your application a message — whether it’s a reply to one of your outbound messages templates, or they have initiated communication themselves — your application has a 24-hour window to send that user any messages, without using a template. These are known as Session Messages.
Text messages are messages containing only a text body.
For more information, go to the Text messages section.
