SummaInstall

Overview

This node, named "Summa," interacts with the Summa API to perform various operations related to telecommunications data management. Specifically, for the resource IMS Subscription and operation Delete IMS Subscription For IMSI, it deletes an IMS subscription record identified by a given IMSI (International Mobile Subscriber Identity). This is useful in scenarios where a subscriber's IMS subscription needs to be removed from the system, such as when deactivating a service or cleaning up outdated subscriber data.

Practical examples include:

• Removing IMS subscriptions of users who have terminated their contracts.
• Automating cleanup of IMS subscriptions during SIM swaps or subscriber profile updates.
• Managing subscriber lifecycle events in telecom backend systems.

Properties

Output

The node outputs JSON data representing the result of the delete operation. Typically, this will include confirmation of deletion or any relevant status messages returned by the Summa API. The exact structure depends on the API response but generally indicates success or failure of the deletion request.

If the node supports binary data output, it would relate to any files or attachments returned by the API, but based on the provided code and context, no binary output is expected for this operation.

Dependencies

• Requires connection to the Summa API via an API key credential configured in n8n.
• Uses internal helper classes for HTTP requests, state management, and operation resolution.
• The node depends on the summaApi credential which must be properly set up and tested before execution.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI value: Ensure the IMSI input is correctly provided and formatted.
  • Authentication errors: Verify that the API key credential is valid and has necessary permissions.
  • Network or connectivity problems: Check network access to the Summa API endpoint.
  • API errors due to non-existent IMSI: The API may return an error if the IMSI does not exist; handle such cases gracefully.

• Error messages:

  • Authentication failures typically indicate invalid credentials; reconfigure the API key.
  • Validation errors on IMSI input suggest missing or malformed IMSI values.
  • HTTP errors (e.g., 404, 500) indicate server-side issues or incorrect API usage; consult API documentation or logs.
