Overview
This node integrates with the Uzapi API, a service for interacting with WhatsApp. It enables sending various types of messages such as text, links, images, files, audio, and video to specified phone numbers via WhatsApp.
The "Enviar Imagem" (Send Image) operation specifically allows users to send an image message to a WhatsApp number by providing the recipient's phone number, a link to the image, and an optional caption describing the image.
Common scenarios:
- Sending promotional images or product photos to customers.
- Sharing event flyers or invitations via WhatsApp.
- Automating image-based notifications or alerts.
Example:
A marketing automation workflow sends a product catalog image to a list of customers by specifying their phone numbers and the image URL, optionally including a caption describing the product.
