Overview
This node integrates with the Evolution API to send image messages. Specifically, for the "Mensagem" resource and the "Enviar Imagem" operation, it allows users to send an image (via URL or base64) to a specified recipient number through a chosen instance. This is useful in scenarios where automated image sharing is needed, such as sending product photos, event flyers, or visual notifications directly via messaging platforms.
Practical examples:
- Sending promotional images to customers automatically.
- Sharing screenshots or diagrams in support workflows.
- Broadcasting event invitations with images to group chats.
Properties
| Name | Meaning |
|---|---|
| Nome Da Instancia | The name of the instance that will send the message. |
| Número Do Destinatário | The recipient's phone number or identifier to which the image will be sent. |
| Imagem | The image to send, provided as a URL or base64 string. |
| Caption | Optional text caption to accompany the image. |
| Opções | Additional options for the message: |
| - Delay | Time in milliseconds to wait before sending the message (default 1200 ms). |
| - Responder Mensagem | Option to reply to a specific message by providing its ID. |
| - Menções | Settings to mention participants: either mention everyone in a group or specify numbers to mention (comma-separated). |
Output
The node outputs a JSON array containing the response from the Evolution API after attempting to send the image message. The exact structure depends on the API response but typically includes confirmation details such as message ID, status, timestamps, or error information if the send failed.
No binary data output is indicated.
Dependencies
- Requires an API key credential for authenticating with the Evolution API.
- The node expects proper configuration of this credential within n8n.
- Network access to the Evolution API endpoint is necessary.
- The image can be provided as a URL accessible by the API or as a base64 encoded string.
Troubleshooting
Common issues:
- Invalid or missing instance name or recipient number will cause failures.
- Providing an invalid image URL or malformed base64 string may result in errors.
- Insufficient permissions or incorrect API credentials will prevent message sending.
- Delay values too low might cause rate limiting or unexpected behavior.
Error messages:
- "Operação não suportada." indicates the requested operation is not implemented; verify correct resource and operation names.
- API errors returned in the response should be checked for authentication issues, invalid parameters, or quota limits.
Resolutions:
- Double-check all required fields are filled correctly.
- Validate image URLs or base64 strings before use.
- Ensure API credentials are valid and have necessary permissions.
- Adjust delay settings if encountering rate limits.
