Overview
This node enables sending various types of WhatsApp messages through the Wuzapi service, optimized for AI workflows. It supports sending text, images, documents, audio, video, location, and contact messages to specified phone numbers in international format.
Common scenarios include:
- Automating customer support by sending text or media responses.
- Broadcasting multimedia content like promotional images or audio clips.
- Sharing location or contact information dynamically within conversations.
For example, you can send an audio message to a client with a voice note or share a document such as a PDF invoice directly via WhatsApp.

Dependencies

Troubleshooting
