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 LTE Subscription resource and the Get Apn Info operation, it retrieves APN (Access Point Name) information based on a provided IMSI (International Mobile Subscriber Identity). This is useful in telecom environments where you need to query subscriber data related to LTE network configurations.

Practical examples include:

  • Fetching APN details for a subscriber to troubleshoot connectivity issues.
  • Validating subscriber configuration during provisioning or auditing.
  • Integrating subscriber APN info into broader workflows for network management or billing.

Properties

Name Meaning
Imsi The IMSI (International Mobile Subscriber Identity) of the LTE subscriber whose APN information you want to retrieve. This is a required string input.

Output

The node outputs JSON data containing the APN information associated with the given IMSI. The exact structure depends on the Summa API response but typically includes fields describing APN settings such as APN name, type, QoS parameters, and other LTE subscription details.

If the node supports binary data output, it would be used to represent any non-JSON payloads returned by the API, but this is not evident from the provided code snippet.

Dependencies

  • Requires an API key credential to authenticate with the Summa API.
  • Uses an HTTP client internally to make requests to the Summa backend service.
  • The node depends on the external Summa API service being available and reachable.
  • No additional environment variables or n8n-specific configurations are explicitly required beyond the API credential.

Troubleshooting

  • Common Issues:

    • Invalid or missing IMSI parameter will cause the operation 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 responses or changes in the Summa API version might cause parsing errors.

  • Error Messages:

    • Authentication failures usually indicate invalid credentials; verify and update the API key.
    • Parameter validation errors suggest missing or malformed IMSI input; ensure the IMSI is correctly provided.
    • Timeout or connection errors imply network issues; check connectivity and API availability.
