Overview

The 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 GMLC Numbers, it retrieves GMLC (Gateway Mobile Location Center) numbers associated with a given IMSI (International Mobile Subscriber Identity). This operation is useful in telecommunications scenarios where location services or subscriber data management are required.

Practical examples include:

  • Querying the GMLC numbers linked to a subscriber's IMSI for location-based services.
  • Integrating with telecom backend systems to fetch subscriber-related routing or location information.

Properties

Name Meaning
Imsi The International Mobile Subscriber Identity (IMSI) string identifying the subscriber whose GMLC numbers are to be retrieved. This property is required.

Output

The output of this node will be JSON data containing the GMLC numbers associated with the provided IMSI. The exact structure depends on the Summa API response but typically includes an array or list of GMLC numbers relevant to the subscriber.

If the node supports binary data output, it would represent any binary payload returned by the API, but based on the provided code and context, the primary output is JSON.

Dependencies

  • Requires an API key credential for authenticating with the Summa API.
  • Uses an HTTP client internally to make requests to the Summa backend service.
  • The node depends on the Summa API being accessible and properly configured with valid credentials in n8n.

Troubleshooting

  • Missing or invalid IMSI: Since IMSI is required, ensure it is provided and correctly formatted; otherwise, the API call may fail or return errors.
  • 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 can cause request failures.
  • Unexpected API responses: If the Summa API changes or returns unexpected data, the node might not parse the output correctly.

Common error messages likely relate to authentication failure, invalid parameters, or network timeouts. Resolving these involves checking credentials, input values, and network access.
