Overview

This node integrates with a WhatsApp-based customer relationship platform, enabling various contact and messaging operations. Specifically, the "Contato - Mensagem - Enviar Imagem + Legenda" operation allows sending an image along with a caption (legend) to a specified WhatsApp contact. This is useful for personalized communication where visual content enhances the message, such as sending product images, promotional materials, or informational graphics directly to customers.

Practical examples include:

Sending a product photo with a description to a client.
Sharing event invitations with an image and accompanying text.
Delivering support-related images with explanatory captions.

Properties

Name	Meaning
Número De Contato	Phone number of the contact including country code (e.g., 5527998282828).
Nome Do Contato	Name of the contact used to personalize the message.
Texto Da Mensagem	Text message that will be sent together with the image.
URL Da Imagem	URL of the image to be sent (maximum size: 1MB).

Output

The node outputs JSON data representing the result of the send image + caption operation. This typically includes confirmation details such as message status, IDs, timestamps, or error information if the sending failed.

If binary data output is supported by other operations in this node, it is not applicable here; this operation focuses on sending media via URL and returns JSON response data only.

Dependencies

Requires connection to the external WhatsApp-based customer relationship platform via an API.
Needs an API authentication token or key configured in n8n credentials to authorize requests.
The image must be accessible via a public URL and comply with size restrictions (max 1MB).

Troubleshooting

Common issues:
- Invalid or incorrectly formatted phone number may cause message delivery failure.
- Image URL inaccessible or exceeding size limit can prevent sending the image.
- Missing or invalid API credentials will block communication with the platform.
- Network connectivity problems may cause timeouts or errors.
Error messages and resolutions:
- "Invalid phone number format": Verify the number includes the correct country code and no extra characters.
- "Image size exceeds limit": Ensure the image URL points to a file smaller than 1MB.
- "Authentication failed": Check that the API key or token is correctly set up in n8n credentials.
- "Unable to reach image URL": Confirm the URL is publicly accessible without authentication.
