Send Text Message
Sends a WhatsApp text message to any mobile number from one of your connected WhatsApp numbers.
This sends a session message — only deliverable if the recipient messaged your business within the last 24 hours (a customer-initiated conversation). To message someone outside that window, use an approved Template Message instead — see Why Templates Exist.
