Zalo User Interact

Overview

This node operation "Create Group" is designed to create a new group by specifying a list of member IDs and optionally a group name. It is useful in scenarios where users want to programmatically manage groups, such as creating chat groups, team collaboration groups, or any collection of users identified by their unique IDs.

Practical examples include:

• Creating a new project team group in a collaboration platform by providing the user IDs of team members.
• Automating the creation of customer segments or interest groups in marketing tools.
• Setting up discussion groups in messaging apps by listing participant IDs.

The node takes a comma-separated string of member IDs and an optional group name, then processes this information to create the group accordingly.

Properties

Output

The output of the node includes a JSON object representing the result of the group creation operation. This typically contains details about the newly created group, such as its ID, name, and the list of members added.

If the node supports binary data output (not explicitly shown in the provided code), it would represent attachments or media related to the group creation process, but based on the static analysis, the primary output is JSON data describing the created group.

Dependencies

• The node requires an API key credential or similar authentication token configured in n8n to authorize requests to the external service managing groups.
• It depends on an external API or service endpoint that handles group creation given member IDs and group name.
• The node uses internal helper libraries for HTTP requests and error handling (not detailed here due to obfuscation).

Troubleshooting

Common Issues

• Invalid Member IDs: If the member IDs string is malformed or contains invalid IDs, the group creation may fail.
• Missing Required Fields: Omitting the required "Members" property will cause the node to throw an error.
• Authentication Errors: Incorrect or missing API credentials will prevent successful communication with the external service.
• API Rate Limits: Excessive requests might lead to throttling or rate limit errors from the external API.

Error Messages and Resolutions

• "Members field is required": Ensure the "Members" input property is provided and correctly formatted.
• "Authentication failed": Verify that the API key or authentication token is correctly set up in n8n credentials.
• "Group creation failed": Check the response message from the external API for specific reasons; validate member IDs and group name.
• Unhandled exceptions: Review the node's execution logs for stack traces and ensure all required inputs are valid.
