SummaInstall

Overview

The node integrates with the Summa API to perform various operations related to telecommunications subscriptions and services. Specifically, for the HLR Subscription resource and the Remove PDP Address Assignation operation, it removes a previously assigned Packet Data Protocol (PDP) address template from a subscriber identified by their IMSI (International Mobile Subscriber Identity). This is useful in scenarios where a mobile subscriber's data session configuration needs to be updated or cleared, such as deactivating certain data services or correcting subscription details.

Practical examples include:

• Removing an outdated or incorrect PDP context assignment from a subscriber.
• Managing subscriber profiles dynamically in telecom systems to control data access.

Properties

Output

The node outputs JSON data representing the result of the remove operation. This typically includes confirmation of success or failure, status messages, and any relevant metadata returned by the Summa API about the removal of the PDP address assignation.

If the operation supports binary data output (not indicated here), it would represent associated files or raw data responses, but this node primarily deals with JSON responses.

Dependencies

• Requires an API key credential for authenticating with the Summa API.
• Depends on the Summa API service being accessible and properly configured.
• Uses internal helper classes for HTTP requests, state management, and operation resolution/execution.
• No additional environment variables are explicitly required beyond the API credential.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI or PDP Template values will cause the operation to fail.
  • Authentication errors if the API key credential is invalid or expired.
  • Network connectivity problems preventing access to the Summa API endpoint.
  • API-side errors if the specified PDP template does not exist or is not assigned to the given IMSI.

• Error messages and resolutions:

  • "Authentication failed": Verify the API key credential and renew if necessary.
  • "Invalid IMSI or PDP Template": Check input values for correctness and completeness.
  • "Resource not found" or "Operation failed": Confirm that the PDP template is currently assigned to the IMSI before attempting removal.
  • Timeouts or network errors: Ensure stable internet connection and correct API endpoint configuration.
