Zalo User Interact

Overview

This node is designed to retrieve information about specific groups from a service (likely Facebook Groups, based on the context). The primary operation "Get Group Info" allows users to input one or more group IDs and fetch detailed information about those groups.

Common scenarios where this node would be beneficial include:

• Automating the retrieval of group metadata for reporting or monitoring purposes.
• Integrating group data into workflows that require group details, such as membership counts, descriptions, or other attributes.
• Synchronizing group information with external databases or CRM systems.

Practical example:

• A social media manager wants to automatically pull updated information about multiple Facebook groups they manage to track changes in group settings or membership statistics. They can use this node to input the list of group IDs and receive structured data about each group.

Properties

The property "Group IDs" is a fixed collection allowing multiple values, meaning you can specify multiple group IDs at once.

Output

The node outputs an array of JSON objects, each representing the information of a requested group. Each object contains detailed fields corresponding to the group's metadata as returned by the underlying API.

If the node supports binary data output (e.g., images or files related to groups), it would be included in the binary field; however, based on the provided code and operation, the output primarily consists of JSON data describing group information.

Dependencies

• Requires an API key credential or authentication token configured in n8n to access the external service's API.
• Depends on the external service's API endpoint(s) to fetch group information.
• Uses internal helper libraries and possibly file system modules for handling attachments or caching (as inferred from bundled dependencies).
• No explicit environment variables are mentioned, but proper API credentials must be set up in n8n.

Troubleshooting

Common Issues

• Invalid or missing Group IDs: If the input group IDs are incorrect or not provided, the node may fail to retrieve any data.
• Authentication errors: Missing or invalid API credentials will cause authorization failures.
• API rate limits: Requesting too many groups at once or too frequently might trigger rate limiting by the external service.
• Network issues: Connectivity problems can prevent successful API calls.

Error Messages and Resolutions

• Authorization failed: Check that the API key or authentication token is correctly configured and has sufficient permissions.
• Group not found: Verify that the provided Group IDs are valid and accessible by the authenticated user.
• Rate limit exceeded: Implement delays or reduce the number of group IDs per request.
• Unexpected response or timeout: Ensure network connectivity and that the external API is operational.
