Evolution API

Interact with Evolution API

Actions64

Overview

This node, named "Evolution API," is designed to interact with the Evolution API service. Specifically, for the Chat resource and the Fetch Profile Picture operation, it retrieves the profile picture of a specified contact from a chat instance. This can be useful in automation workflows where you want to display or process user profile images dynamically, such as in customer support dashboards, contact management systems, or social media integrations.

Properties

Name Meaning
Name Da Instância The name of the chat instance from which to fetch the profile picture.
Contato The phone number of the contact whose profile picture you want to retrieve (e.g., 5511999999999).

Output

The node outputs a JSON array containing the result of the fetch profile picture operation. The exact structure depends on the Evolution API response but typically includes:

  • The profile picture data or URL associated with the specified contact.
  • Metadata related to the contact or image.

If the profile picture is returned as binary data, it would be included accordingly, but based on the code and typical API behavior, the output is most likely JSON with image URLs or base64 encoded strings.

Dependencies

  • Requires an active connection to the Evolution API service.
  • Needs an API authentication credential configured in n8n to authorize requests.
  • The node uses the base URL https://doc.evolution-api.com/api-reference for API calls.

Troubleshooting

  • Operation not supported error: If you select an unsupported operation or resource, the node throws an error indicating the function is not supported. Ensure that the resource is set to "chat" and the operation to "fetch-profile-picture."
  • Missing or invalid credentials: The node requires valid API credentials; ensure these are correctly configured.
  • Invalid contact number format: The contact number must be in the correct international format (e.g., 5511999999999). Incorrect formatting may cause the API call to fail.
  • Instance name required: The instance name property is mandatory; leaving it empty will cause errors.
  • Network or API errors: Check network connectivity and API availability if requests fail unexpectedly.
