Relacio - WhatsApp

Overview

This node integrates with a platform for WhatsApp relationship management and offers many operations related to contacts, messaging, protocols, groups, marketing campaigns, and extra data lookups. Specifically, the "Extra - Transcrição - Imagem EN" operation generates an English caption (transcription) from an image URL.

A common use case for this operation is automatically generating descriptive captions for images hosted online, which can be useful in content automation, accessibility improvements, or social media workflows where image descriptions are needed in English.

Example: Given a URL of an image, the node fetches and processes it to produce a textual caption describing the image content in English.

Properties

Output

The node outputs JSON data containing the generated English caption text derived from the provided image URL. The exact structure is not detailed in the source code, but typically it would include at least a field with the caption string.

No binary data output is indicated for this operation.

Dependencies

• Requires an API key credential for the external WhatsApp relationship platform.
• The node depends on internal action implementations (not fully visible here) that handle the actual image transcription logic.
• Network access to the image URL and the external service is necessary.

Troubleshooting

• Invalid or inaccessible image URL: If the URL is incorrect or the image cannot be fetched, the operation will likely fail. Ensure the URL is publicly accessible and points directly to an image file.
• API authentication errors: Missing or invalid API credentials will cause authorization failures. Verify that the required API key or token is correctly configured in n8n credentials.
• Unsupported image formats: If the image format is unsupported by the transcription service, the caption generation may fail or return empty results.
• Network issues: Connectivity problems to either the image URL or the external API endpoint can cause timeouts or errors.

Error messages should guide checking these areas, and users should confirm all inputs and credentials are correct.
