Zalo User Interact

Overview

This node operation "Add User To Group" for the "Group" resource is designed to add a specified user to a particular group within the Zalo platform. It facilitates managing group memberships programmatically, which is useful in automating workflows involving group collaboration or communication.

Common scenarios where this node would be beneficial include:

• Automatically adding new users to project or team groups based on certain triggers.
• Managing membership of event or interest-based groups dynamically.
• Integrating with CRM or user management systems to synchronize group memberships.

Practical example:

• When a new employee joins a company (triggered by an HR system), this node can automatically add their Zalo user ID to the company's internal communication group.

Properties

Output

The node outputs an array of JSON objects representing the results of the add user to group operation for each input item. Each output object typically contains:

• A success indicator or status.
• Any relevant metadata or confirmation details returned from the Zalo API about the addition.
• Error information if the operation failed for a specific user or group.

If the node supports binary data output (not explicitly shown in the provided code), it would represent any files or media related to the operation, but this is not indicated here.

Dependencies

• Requires access to the Zalo API, specifically endpoints that manage group memberships.
• Needs an API authentication token or API key credential configured in n8n to authorize requests to Zalo.
• Uses external libraries such as fs and possibly others bundled in the source for handling file operations or HTTP requests.
• The node implementation depends on asynchronous calls to the Zalo API client library wrapped inside the execute method.

Troubleshooting

Common Issues

• Invalid User Id or Group Id: If either ID is incorrect or does not exist, the API call will fail.
• Insufficient Permissions: The API token used might lack permissions to modify group memberships.
• Network or API Errors: Connectivity issues or rate limiting by Zalo API could cause failures.

Common Error Messages

• "User not found" or "Group not found": Verify the correctness of the IDs.
• "Unauthorized" or "Authentication failed": Check API credentials and permissions.
• "API rate limit exceeded": Implement retry logic or reduce request frequency.

Resolution Steps

• Double-check input property values for accuracy.
• Ensure the API key credential has the necessary scopes.
• Monitor API usage and handle errors gracefully in workflows.
