Overview

This node, named "Summa," integrates with the Summa API to perform various operations related to telecommunications data. Specifically, for the resource WLAN Subscription and operation Get APN Assignations From WLAN Subscription, it retrieves the Access Point Name (APN) assignations associated with a given WLAN subscription identified by an IMSI (International Mobile Subscriber Identity). This is useful in scenarios where you need to query or audit the APN configurations assigned to a subscriber's WLAN service.

Practical examples include:

  • Telecom operators verifying which APNs are assigned to a subscriber's WLAN subscription.
  • Network administrators auditing subscriber configurations for troubleshooting or compliance.
  • Systems that automate subscriber management workflows requiring APN details.

Properties

Name Meaning
Imsi The International Mobile Subscriber Identity (IMSI) of the WLAN subscription for which to retrieve APN assignations. This is a required string input.

Output

The node outputs JSON data containing the APN assignations linked to the specified WLAN subscription IMSI. The exact structure depends on the Summa API response but typically includes details about each APN assigned, such as APN names, identifiers, and possibly configuration parameters.

If the node supports binary data output, it would represent any non-JSON payloads returned by the API; however, based on the provided code and context, the output is primarily JSON.

Dependencies

  • Requires an active connection to the Summa API via an API key credential configured in n8n.
  • Uses internal helper classes for HTTP requests and state management.
  • No additional external services beyond the Summa API are indicated.

Troubleshooting

  • Missing or invalid IMSI: Since IMSI is required, ensure it is provided and correctly formatted. Errors may occur if IMSI is empty or malformed.
  • Authentication errors: If the API key credential is missing, invalid, or expired, the node will fail to authenticate with the Summa API.
  • API connectivity issues: Network problems or incorrect API endpoint configurations can cause request failures.
  • Unexpected API responses: Changes in the Summa API or unexpected data formats might lead to parsing errors.

To resolve these:

  • Verify the IMSI input value.
  • Check and update the API authentication credentials.
  • Ensure network connectivity to the Summa API endpoint.
  • Review API documentation for any changes affecting the response format.
