SummaInstall

Overview

The node named "Summa" integrates with the Summa API (version indicated in the code) to perform various operations on different resources. Specifically, for the LTE Subscription resource and the Set Scef Permissions operation, this node allows users to update or configure SCEF (Service Capability Exposure Function) permissions associated with a particular LTE subscription identified by an IMSI (International Mobile Subscriber Identity).

This node is beneficial in telecom environments where managing subscriber permissions and capabilities programmatically is required. For example, a network operator might use this node to enable or restrict certain service capabilities for a subscriber dynamically based on business rules or regulatory requirements.

Practical examples:

• Updating SCEF permissions for a subscriber after a policy change.
• Automating permission adjustments during subscriber lifecycle events.
• Integrating with other systems that trigger permission changes based on external inputs.

Properties

Output

The node outputs JSON data representing the result of the Set Scef Permissions operation. This typically includes confirmation of the updated permissions, status messages, or any relevant metadata returned by the Summa API regarding the operation's success or failure.

If the node supports binary data output, it would relate to any binary payloads returned by the API, but based on the provided code and context, the primary output is structured JSON reflecting the operation outcome.

Dependencies

• Requires an active connection to the Summa API via an API key credential configured in n8n.
• The node depends on internal helper classes for HTTP requests, state management, and operation resolution/execution.
• No additional external services beyond the Summa API are explicitly required.

Troubleshooting

• Common Issues:

  • Invalid or missing IMSI value: Ensure the IMSI is correctly formatted and provided.
  • Incorrect SCEF permissions format: Validate the permissions string matches expected API schema.
  • Authentication failures: Verify the API key credential is valid and has necessary permissions.
  • Network connectivity issues: Confirm that the n8n instance can reach the Summa API endpoint.

• Error Messages:

  • Authentication errors typically indicate invalid credentials; reconfigure the API key.
  • Validation errors from the API may point to malformed input properties; review IMSI and permissions values.
  • Timeout or network errors suggest connectivity problems; check firewall and network settings.
