Overview
The WhatsApp MB node for n8n allows you to interact with the WhatsApp Cloud API. Specifically, when using the Default resource and the Mark as Read operation, this node marks a specific received WhatsApp message as "read" using its Message ID. This is useful in automated workflows where you want to programmatically acknowledge incoming messages, such as after processing or responding to them.
Practical Example:
- After receiving and processing a customer inquiry via WhatsApp, use this node to mark the message as read, signaling that it has been handled.
