Zalo User Interact

Overview

This node operation creates a new group by specifying a list of member IDs and optionally a group name. It is useful in scenarios where you want to programmatically manage groups of users or entities, such as creating chat groups, project teams, or user segments within an application.

Practical examples include:

• Creating a messaging group with specific users.
• Forming a team for a project management tool.
• Defining a custom audience segment for marketing campaigns.

The node expects a comma-separated string of member IDs and optionally a group name. It processes these inputs, interacts with an external service (likely via API calls), and returns the result of the group creation.

Properties

Output

The output JSON contains an array of results corresponding to the group creation process. Each item typically includes:

• A success flag indicating if the group was created successfully.
• Details about the created group, such as its ID, name, and member list.
• Error information if the creation failed.

If binary data is returned (not explicitly shown in the provided code), it would represent attachments or files related to the group creation but this node primarily outputs JSON data describing the group.

Dependencies

• Requires an API key credential or similar authentication token configured in n8n to authorize requests to the external service managing groups.
• Uses external libraries for HTTP requests and file system operations (e.g., fs module).
• The node depends on a helper class or SDK (Q7 in the code) that handles API interactions.
• Proper configuration of environment variables or credentials in n8n is necessary for successful execution.

Troubleshooting

Common Issues

• Invalid Member IDs: If the members string is malformed or contains invalid IDs, the API may reject the request.
• Missing Required Fields: Omitting the required "Members" property will cause the node to fail.
• Authentication Errors: Incorrect or missing API credentials will prevent the node from communicating with the external service.
• API Rate Limits: Excessive requests might trigger rate limiting errors from the external API.
• File Handling Errors: If attachments are involved, file path issues or permission errors could occur.

Common Error Messages

• "Members field is required": Ensure the "Members" input is provided and correctly formatted.
• "Authentication failed": Verify that the API key or authentication token is correctly set up in n8n.
• "Group creation failed": Check the error details returned by the API; it may indicate invalid parameters or server issues.
• "File not found" or "Permission denied": Confirm that any referenced files exist and are accessible by n8n.

Resolving these usually involves validating inputs, checking credentials, and reviewing API documentation for correct usage.
