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.
Location messages allow you to send a location's latitude and longitude coordinates to a WhatsApp user.
For more information, go to the Location messages section.
