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 HLR Subscription resource and the Set HLR ODB Profile operation, this node allows users to update or set the ODB (Operator Determined Barring) profile associated with a subscriber's IMSI (International Mobile Subscriber Identity). This is useful in telecom scenarios where controlling call barring or restrictions at the HLR (Home Location Register) level is required.

Practical examples include:

  • Enabling or disabling specific call barring profiles for subscribers.
  • Managing subscriber access restrictions dynamically via API calls.
  • Automating telecom subscriber profile updates as part of larger workflows.

Properties

Name Meaning
Imsi The International Mobile Subscriber Identity number identifying the subscriber whose HLR ODB profile is to be set. This is a required string input.
Odb The Operator Determined Barring profile value to assign to the subscriber's HLR record. This is a required string input representing the barring profile.

Output

The node outputs data in JSON format reflecting the result of the Set HLR ODB Profile operation. Typically, this will include confirmation of the update, status codes, or error messages returned by the Summa API. The exact structure depends on the API response but generally includes fields indicating success or failure and any relevant details about the updated subscriber profile.

No binary data output is indicated or expected from this operation.

Dependencies

  • Requires an active connection to the Summa API service.
  • Needs an API authentication credential configured in n8n (referred to generically as an API key credential).
  • Uses internal helper classes for HTTP requests, state management, and operation resolution within the node implementation.
  • No additional external dependencies beyond the Summa API and its credentials.

Troubleshooting

  • Common issues:

    • Invalid or missing IMSI or ODB values will cause the API call to fail.
    • Authentication errors if the API credential is incorrect or expired.
    • Network connectivity problems preventing communication with the Summa API endpoint.

  • Error messages:

    • Authentication failures typically indicate invalid credentials; verify and update the API key credential.
    • Validation errors from the API may specify which input parameter is incorrect; ensure IMSI and ODB are correctly formatted.
    • Timeout or network errors suggest checking internet connectivity or API service availability.

Links and References

  • Summa API official documentation (refer to your organization's API docs for detailed parameters and responses).
  • n8n documentation on creating and using API credentials.
  • Telecom standards references for IMSI and ODB profiles for deeper understanding of these concepts.
