Overview

This node integrates with the Summa API to perform various operations related to telecommunications data management. Specifically, for the "HLR Subscription" resource and the "get HLR Profile" operation, it retrieves the Home Location Register (HLR) profile associated with a given IMSI (International Mobile Subscriber Identity). This is useful in scenarios where you need to query subscriber information stored in the HLR database, such as verifying subscriber status, roaming information, or network details.

Practical examples include:

  • Telecom operators checking subscriber profiles before provisioning services.
  • Fraud detection systems validating subscriber identities.
  • Customer support tools retrieving subscriber network details on demand.

Properties

Name Meaning
Imsi The International Mobile Subscriber Identity string used to identify the subscriber whose HLR profile is being requested. This property is required.

Output

The node outputs JSON data representing the HLR profile corresponding to the provided IMSI. The structure of this JSON typically includes subscriber details such as subscription status, service restrictions, roaming permissions, and other relevant HLR attributes.

If the node supports binary data output, it would generally relate to raw response payloads or attachments from the API, but based on the provided code and context, the output is primarily JSON-formatted subscriber profile data.

Dependencies

  • Requires an active 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.
  • No additional external dependencies beyond the Summa API and its authentication.

Troubleshooting

  • Missing or invalid IMSI: Since IMSI is required, ensure it is provided and correctly formatted; otherwise, the node will likely throw an error indicating missing parameters.
  • Authentication errors: If the API key credential is invalid or expired, the node will fail to authenticate with the Summa API. Verify that the API key is correct and has necessary permissions.
  • Network issues: Connectivity problems to the Summa API endpoint can cause request failures. Check network access and API availability.
  • Unexpected API responses: If the Summa API returns errors or unexpected data structures, verify the IMSI value and consult the API documentation for valid inputs.
