SummaInstall

Overview

This node, named "Summa," integrates with the Summa API to perform various operations on different resources. Specifically, for the LTE Subscription resource and the Add Apn operation, it allows users to add an Access Point Name (APN) configuration to a given LTE subscription identified by its IMSI (International Mobile Subscriber Identity). This is useful in telecom environments where managing subscriber data and network access configurations programmatically is required.

Practical examples include:

• Adding a new APN profile to a subscriber's LTE subscription to enable specific data routing or services.
• Automating bulk updates of APN settings across multiple subscribers.
• Integrating with backend systems to dynamically adjust subscriber network parameters based on business logic.

Properties

Output

The node outputs JSON data representing the result of the Add Apn operation. This typically includes confirmation of the APN addition, any updated subscriber information, or error details if the operation failed.

If the node supports binary data output, it would generally relate to raw response payloads or files returned by the API, but this is not indicated in the provided code snippet.

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

• Common issues:

  • Invalid or missing IMSI value causing the API to reject the request.
  • Incorrect APN strings leading to validation errors.
  • Authentication failures due to invalid or expired API credentials.
  • Network connectivity problems preventing communication with the Summa API.

• Error messages and resolutions:

  • "Authentication failed": Verify the API key credential is correctly set up and has necessary permissions.
  • "Invalid IMSI" or "Subscriber not found": Confirm the IMSI value corresponds to an existing LTE subscription.
  • "APN format error": Ensure the APN string follows expected formatting rules.
  • Timeout or network errors: Check network connectivity and API endpoint availability.
