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.
Contacts messages allow you to send rich contact information directly to WhatsApp users, such as names, phone numbers, physical addresses, and email addresses.
For more information, go to the Contacts messages section.
