SummaInstall

Overview

This node, named "Summa," is designed to interact with the Summa API (version indicated in the node description). Specifically, for the HLR Subscription resource and the Get Bearer Service operation, it retrieves bearer service information associated with a given IMSI (International Mobile Subscriber Identity). This can be useful in telecommunications scenarios where you need to query subscriber bearer service details, such as checking active data or voice services linked to a mobile subscriber.

Practical examples include:

• Validating subscriber service status before provisioning new services.
• Auditing or monitoring subscriber bearer capabilities.
• Integrating subscriber data into broader telecom management workflows.

Properties

Output

The node outputs JSON data containing the bearer service details retrieved from the Summa API for the specified IMSI. The exact structure depends on the API response but typically includes fields describing the subscriber's bearer services, such as service types, statuses, and related metadata.

If the API supports binary data output (not evident from the provided code), it would represent any binary payloads returned by the Summa API, but this node primarily deals with JSON responses.

Dependencies

• Requires an API key credential for authenticating with the Summa API.
• Uses an HTTP client internally to send requests to the Summa backend.
• Relies on the Summa API being accessible and properly configured.
• The node expects the user to have configured the necessary credentials within n8n for the Summa API.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI parameter will cause the request to fail.
  • Authentication errors if the API key credential is incorrect or expired.
  • Network connectivity problems preventing access to the Summa API endpoint.
  • Unexpected API response formats or errors from the backend.

• Error messages and resolutions:

  • Authentication failed: Verify that the API key credential is correctly set up and valid.
  • Missing required parameter 'imsi': Ensure the IMSI property is provided and correctly formatted.
  • Network error or timeout: Check network connectivity and API endpoint availability.
  • Unexpected response: Confirm that the Summa API version matches the node expectations and that the API is functioning normally.
