Overview

This node, named "Summa," is designed to interact with the Summa API (version indicated in the code). Specifically, for the resource HLR Subscription and operation Get CSE Notification Profile, it retrieves the CSE (Common Service Entity) notification profile associated with a given IMSI (International Mobile Subscriber Identity). This can be useful in telecommunications scenarios where you need to query subscriber-related notification profiles from a Home Location Register (HLR) system.

Practical examples include:

  • Fetching notification profiles for mobile subscribers to monitor service status or changes.
  • Integrating telecom backend systems with external workflows that require subscriber data validation or updates.
  • Automating telecom operations that depend on subscriber notification settings.

Properties

Name Meaning
Imsi The IMSI (International Mobile Subscriber Identity) of the subscriber whose CSE Notification Profile is to be retrieved. This is a required string input.

Output

The node outputs JSON data representing the CSE Notification Profile corresponding to the provided IMSI. The exact structure depends on the Summa API response but typically includes details about the subscriber's notification settings within the HLR system.

No binary data output is indicated by the source code.

Dependencies

  • Requires an API key credential for authenticating with the Summa API.
  • Uses an HTTP client internally to send requests to the Summa backend.
  • The node depends on the summaApi credential configured in n8n for authentication.
  • No additional environment variables are explicitly required beyond this credential.

Troubleshooting

  • Missing or invalid IMSI: Since IMSI is required, ensure it is provided and correctly formatted; otherwise, the API call will fail.
  • Authentication errors: If the API key credential is missing, invalid, or expired, the node will not authenticate successfully. Verify the credential configuration.
  • API connectivity issues: Network problems or incorrect endpoint configurations may cause request failures.
  • Unexpected API responses: If the Summa API changes or returns errors, the node might throw errors or return incomplete data. Check API documentation and logs.
