Overview

This node operation "Lists Permissions of a Given User" under the "Permission" resource retrieves all permissions assigned to a specific user identified by their unique user ID. It is useful in scenarios where you need to audit or verify what access rights a particular user has within a system, such as checking roles, document access, or other permission scopes.

Practical examples include:

  • Auditing user permissions before granting additional access.
  • Displaying user permissions in an admin dashboard.
  • Automating compliance checks by listing permissions programmatically.

Properties

Name Meaning
User ID The unique identifier of a user whose permissions you want to list. This is a required string input.

Output

The output will be a JSON object containing the list of permissions associated with the specified user. Each permission entry typically includes details such as permission name, scope, and possibly metadata about the permission assignment.

If the node supports binary data output (not indicated here), it would represent related files or tokens, but for this operation, the output is purely JSON-based permission data.

Dependencies

  • Requires an API key credential configured in n8n to authenticate requests against the external service's API.
  • The node sends an HTTP GET request to the endpoint /users/{user_id}/permissions to fetch the permissions.
  • Proper network connectivity and valid credentials are necessary for successful execution.

Troubleshooting

  • Missing or invalid User ID: Ensure the User ID property is provided and correctly formatted; otherwise, the API call will fail.
  • Authentication errors: Verify that the API key credential is correctly set up and has sufficient permissions to query user permissions.
  • User not found: If the user ID does not exist, the API may return a 404 error; confirm the user ID is valid.
  • API rate limits or timeouts: Large permission sets or network issues might cause timeouts; consider adding retries or increasing timeout settings.

Links and References

  • Refer to the external API documentation for user permissions endpoint for detailed response schema and permission types.
  • n8n documentation on setting up API key credentials and HTTP request nodes for further customization.
