SummaInstall

Overview

This node integrates with the Summa API to manage various telecommunications resources. Specifically, for the WLAN Subscription resource and the Set APN Assignations To WLAN Subscription operation, it allows users to assign Access Point Names (APNs) to a WLAN subscription identified by an IMSI (International Mobile Subscriber Identity). This is useful in scenarios where network operators or service providers need to configure or update the APN settings associated with a subscriber's WLAN profile, enabling proper routing of data traffic.

Practical examples include:

• Updating APN assignments when a subscriber changes their data plan.
• Configuring multiple APNs for different services on a single WLAN subscription.
• Automating bulk updates of APN assignments across many subscribers.

Properties

Output

The node outputs JSON data reflecting the result of the APN assignment operation on the WLAN subscription. This output typically contains confirmation of success, updated subscription details, or error information if the operation failed.

If the node supports binary data output, it would relate to any files or attachments returned by the API, but based on the provided code and properties, this operation primarily deals with JSON responses.

Dependencies

• Requires connection to the Summa API via an API key credential configured in n8n.
• Uses an HTTP client internally to communicate with the Summa backend.
• Depends on the Summa API version as indicated in the node description.
• No additional external dependencies are evident from the static code.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI value will cause the operation to fail because the target subscription cannot be identified.
  • Incorrectly formatted APN assignments string may lead to API errors or rejection.
  • Authentication failures due to invalid or expired API credentials.
  • Network connectivity issues preventing communication with the Summa API.

• Error messages and resolutions:

  • "Authentication failed": Verify that the API key credential is correctly configured and has not expired.
  • "Invalid IMSI" or "Subscription not found": Confirm the IMSI value is correct and corresponds to an existing WLAN subscription.
  • "Malformed APN assignments": Ensure the APN assignments string follows the expected format required by the Summa API.
  • Timeout or network errors: Check network connectivity and API endpoint availability.
