Overview
The node "Evolution API" allows interaction with the Evolution API service. Specifically, for the Group resource and the Update Group Picture operation, it updates the profile picture of a specified group within an instance. This is useful in scenarios where group images need to be programmatically changed or refreshed, such as updating branding, event-specific images, or correcting outdated pictures.
Practical examples:
- Automatically update a group’s photo when a new event banner is published.
- Change group images based on seasonal themes or campaigns.
- Synchronize group photos across multiple instances or platforms.
Properties
| Name | Meaning |
|---|---|
| Instance Name | The name of the instance that will perform the image update on the group. |
| Group ID | The unique identifier of the group whose image will be updated. |
| Image URL | The URL pointing to the new image that will be set as the group's profile picture. |
Output
The node outputs a JSON array containing the result of the update operation. Typically, this will include confirmation details such as success status, updated group information, or error messages if the update failed.
If the operation involves binary data (e.g., uploading an image file), the node would handle it accordingly, but here the input is an image URL, so no binary output is expected.
Dependencies
- Requires an active connection to the Evolution API service.
- Needs an API authentication token or API key credential configured in n8n to authorize requests.
- The base URL for the API is
https://doc.evolution-api.com/api-reference. - Proper network access to the provided image URL is necessary for the API to fetch and set the image.
Troubleshooting
- Unsupported operation error: If the node throws an error about unsupported operations, verify that the Resource is set to "Group" and Operation to "Update Group Picture".
- Invalid or inaccessible Image URL: Ensure the image URL is publicly accessible or reachable by the API service; otherwise, the update will fail.
- Authentication errors: Confirm that the API credentials are correctly configured and have sufficient permissions to update group images.
- Incorrect Group ID or Instance Name: Double-check these values to ensure they correspond to existing groups and instances in the Evolution API environment.
