Overview

This node operation, "Get Group Info" under the "Get" resource, is designed to retrieve information about one or more groups by their IDs. It is useful in scenarios where you need to fetch detailed data about specific groups from an external service or API that manages group entities.

Typical use cases include:

• Fetching metadata or details of multiple groups for reporting or monitoring.
• Integrating group information into workflows for automation or decision-making.
• Synchronizing group data between systems.

For example, if you have a list of group IDs representing teams or communities, this node can pull their current information such as names, descriptions, members count, or other attributes provided by the connected service.

Properties

The "Group IDs" property is a fixed collection allowing multiple entries, each requiring a string value representing a single Group ID.

Output

The node outputs an array of JSON objects, each corresponding to the information retrieved for a specified Group ID. The structure of each object depends on the external service's response but generally includes group details such as:

• Group ID
• Group name
• Description
• Member count
• Other relevant metadata fields

No binary data output is indicated in the source code.

Dependencies

• Requires connection to an external API or service that provides group information.
• Needs appropriate API authentication credentials configured in n8n (e.g., an API key or token).
• The node internally uses asynchronous calls to fetch data for each Group ID.

Troubleshooting

Common Issues

• Invalid or missing Group IDs: If a Group ID is incorrect or not found, the node may return an error or empty result for that ID.
• Authentication errors: Missing or invalid API credentials will cause failures when attempting to fetch group info.
• API rate limits: Requesting too many Group IDs at once might hit API rate limits, causing throttling or errors.
• Network issues: Connectivity problems can lead to timeouts or failed requests.

Error Messages and Resolutions

• "Group not found" or similar: Verify that the Group IDs are correct and exist in the external system.
• Authentication errors: Check that the API credentials are correctly set up and valid.
• Timeouts or network errors: Ensure stable internet connection and that the external API endpoint is reachable.
• Rate limit exceeded: Reduce the number of Group IDs per request or implement retry logic with delays.
