WhatsApp Message

Send a free-form WhatsApp session message

Sends a free-form text message inside an active WhatsApp conversation (the 24h customer-care window), without using a template. Target the recipient with "contact_id" or "phone". Only official WhatsApp API numbers are supported; WhatsApp rejects messages sent outside the 24h window.
