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 you want to programmatically manage groups of users or entities, such as creating chat groups, project teams, or any collection of members that need to be grouped together for collaboration or communication.

Practical examples include:

• Creating a new chat group in a messaging platform by providing the user IDs of participants.
• Forming a team in a project management tool by listing the team members.
• Organizing contacts into a group for bulk notifications or permissions.

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 any files or attachments related to the group creation process, but based on the given source, the primary output is JSON data describing the created group.

Dependencies

• The node requires access to an external API or service that manages groups and members. This involves authenticating with an API key or token (referred generically as "an API key credential").
• The node uses internal helper classes and methods (obfuscated in the source) to handle HTTP requests and responses.
• No explicit environment variables are mentioned, but proper API credentials must be configured in n8n for the node to function.

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 errors.
• Authentication Failures: Incorrect or missing API credentials will prevent the node from successfully creating groups.
• API Errors: The external service might return errors due to rate limits, invalid parameters, or server issues.

Error Messages and Resolutions

• "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 credentials.
• "Failed to create group": Check the API response for detailed error messages; ensure all required fields meet the API's expectations.
• Timeouts or Network Errors: Confirm network connectivity and API endpoint availability.
