The SendChatMessage function sends non-template WhatsApp messages within an active Customer Service Window.
How It Works:
- A 24-hour Customer Service Window opens when the customer sends a message to your WhatsApp number (either by replying to a template message you sent or by initiating the conversation themselves).
- Within this active window, you can use this endpoint to send non-template message types such as text, image, document, video, audio, sticker, reaction, location, contact and interactive messages.
- If you need to send utility-type templates within the Customer Service Window, use the
/transactional/whatsappendpoint.
Important: This endpoint can only be used when a Customer Service Window is active. For all template messages (including utility templates), use the /transactional/whatsapp endpoint.
